1. Pt/TiO₂ catalyst for ambient HCHO oxidation

For the first time in the world, we developed a highly efficient and stable Pt/TiO₂ catalyst for the catalytic oxidation of formaldehyde (HCHO), achieving complete catalytic decomposition of formaldehyde into H₂O and CO₂ at room temperature without any external energy input. It was clarified that highly dispersed Pt species on TiO₂ play the key role in determining the activity of the Pt/TiO₂ catalyst for ambient HCHO destruction, and the reaction mechanism of HCHO oxidation over the noble metal catalyst was elucidated. (Catal. Commun., 2005, 6, 211; Appl. Catal. B, 2006, 65, 37; Catal. Today, 2007, 126, 345)

2. Promotion effect of alkali metal ions and oxygen vacancies

It is observed that alkali metal ions have a significant promotion effect on the activity of Pt/TiO₂ for ambient HCHO oxidation. The Na-free catalyst had low activity for HCHO oxidation, with HCHO conversion being only ca. 19% at room temperature. With 2% Na addition, 100% HCHO conversion to CO₂ and H₂O was measured. It was revealed that the alkali metal ions significantly promote the activity of Pt/TiO₂ by inducing atomically dispersed Pt species, thereby opening a new low-temperature reaction pathway. (Angew. Chem. Int. Ed., 2012, 51, 9628）

We observed that Na doping also has a dramatic and common promotion effect on the Pd/TiO₂ and Ir/TiO₂ catalyst systems. It was revealed that Na species addition can facilitate the activation of H₂O and chemisorbed oxygen, therefore resulting in high performance for the Na doped Pd- and Ir-based catalysts for ambient HCHO destruction. In addition, the synergistic effect of H₂O and chemisorbed oxygen on HCHO oxidation was also illuminated. (Environ. Sci. Technol., 2014, 48, 5816; Catal. Sci. Technol., 2016, 6, 2289; Catal. Today, 2017, 281, 412; ACS Catal., 2018, 8, 11377)

We discovered the promotion effect of high temperature reduction on Pd/TiO₂ catalysts for HCHO oxidation. It was found that oxygen vacancies played vital roles in the abnormal phenomenon that high temperature reduction did not induce Pd aggregation, but rather enhanced Pd dispersion. The oxygen vacancies could not only trap the diffusing Pd particles but also facilitate the activation of H₂O and chemisorbed oxygen. The work applied a new concept to design catalysts with high dispersion of supported noble metals. (Appl. Catal. B, 2017, 217, 560)

3. Practical applications of Pt-based catalyst

We have successfully implemented this basic research achievement into practical applications. New Air Cleaners equipped with the novel Pt-based catalyst have been developed and put into the Chinese market, and have already become the best-selling Air Cleaner in China, greatly improving indoor air quality and benefitting the Chinese people.

We have developed a series of Pd-based catalysts with both adsorption capacity and catalytic activity for removal of BTX. By using a Pd/AC catalyst, we established an adsorption in situ catalytic oxidation method for indoor air BTX removal, which simplifies the traditional method “adsorption – desorption – oxidation” to an “adsorption – in situ oxidation” process. The ordered mesoporous Pd/Co₃O₄ (3D) catalyst with more-ordered mesostructure and more well-dispersed PdO species shows excellent activity for o-xylene oxidation. Nanosized CeO₂ particles, cubes, and rods are highly active for catalytic oxidation of o-xylene, and are comparable with traditional noble-metal catalysts, in which oxygen vacancy clusters play key role in the oxidation process. These catalysts are potential materials for removal of VOCs at low temperature. (Appl. Catal. B, 2013, 142-143, 72; Catal. Sci. Technol., 2016, 6, 4840; Sci. Rep., 2017, 7, 12845）

2. Removal of BTX by the combination of non-thermal plasma and catalysis

The effects of different precursors and loading amounts of Mn in the preparation of Mn/Al₂O₃ catalysts for use in plasma-catalytic removal of o-xylene were systematically investigated. Results showed that Mn/Al₂O₃ catalysts could efficiently improve o-xylene conversion with low specific energy density. _.A Mn/Al₂O₃ catalyst prepared with a manganese acetate precursor was found to have excellent catalytic activity for o-xylene removal, with reduced formation of O₃ and NO_x byproducts. More Mn⁴⁺ species, richer lattice oxygen and the presence of the MnO₂ microcrystal phase on the surface of the catalyst were responsible for the high catalytic activity in the oxidation of o-xylene.  (Chem. Eng. J., 2016, 288, 406; J. Phys. Chem. C, 2016, 120, 6136)

3. Oxidation of BTX by electro-catalysis technology

We report, for the first time, a facile gas-solid interface electrochemical oxidation method for the mineralization of benzene compounds at ambient temperature. A membrane electrode assembly (MEA) was used in an all-solid cell. The activity test results showed that 100% benzene compound conversion to CO₂ (85–99%) and CO (15–1%) was achieved at the optimal cell voltage of 2.0 V at relative humidity 60%. Proton-transfer-reaction time-of-flight mass spectrometry and Fourier transform infrared spectroscopy results showed that no organic byproducts could be detected in the anodic reservoir. The electrochemical behavior of the working electrode in benzene solutions with different concentrations revealed that the benzene oxidation process was mainly an indirect oxidation process at the onset potential of OER (2.0 V vs Ag/AgCl, saturated KCl). Our findings provide evidence that the gas-solid interface electrochemical oxidation method has potential as a method for ambient VOC destruction in indoor air environments.  (Chem. Eng.

A series of C-doped TiO₂ catalysts with excellent performance for photocatalytic oxidation of ammonia were prepared, and the catalyst calcined at 400 ^oC had the best activity. The surface acidity is an important factor affecting the performance of a catalyst. The effects of exposed TiO₂ facets and surface F on the activity for photocatalytic oxidation of NH₃ were studied. It was found that TiO₂ with predominant {001} facets exposed had superior activity compared to TiO₂ with {101} or {010} facets exposed, and{001} facets of TiO₂ and surface F ions had a remarkable synergistic effect on PCO of NH₃. The DRIFTS results suggested that the separation efficiency of photogenerated electrons and holes is the crucial factor affecting the performance of NH₃ oxidation, and the main active species for NH₃ oxidation is the hole.  (Appl. Catal. B,2014, 152-153, 82; Appl. Catal. B,2017, 207, 3973; Appl. Catal. B, 2018, 223, 209)

2. Non-photocatalytic oxidation of indoor air ammonia

The Ag species state and Ag particle size have a significant influence on Ag/Al₂O₃ activity and N₂ selectivity in the SCO of NH₃ at low temperature. The SCO of NH₃ over Ag/Al₂O₃ follows different routes in different temperature regions. Ag⁰ is proposed to be an active species at low temperature (< 140 ^oC)，where NH₃ oxidation follows the –NH mechanism. However, at temperatures above 140 ^oC, Ag⁺ could also be an active species, and NH₃ oxidation follows an in situ selective catalytic reduction of NOx (iSCR) mechanism. (J. Catal., 2009, 268, 18; J. Catal., 2009, 261, 101)

Ag/nano-Al₂O₃ is an efficient catalyst for NH₃-SCO in the low temperature range. A remarkable nanosize effect for Al₂O₃ was observed in Ag/Al₂O₃ catalysts for the selective catalytic oxidation of ammonia. Small metallic Ag particles (Ag_NPs) in Ag/nano-Al₂O₃ facilitate the NH₃-SCO reaction following the new reaction pathway, which was named the N₂^– mechanism.

Dispersed Ag species on γ-Al₂O₃ are widely used for catalyzing a variety of reactions, including soot oxidation, ethylene epoxidation, NO_x reduction, and selective catalytic oxidation of ammonia (NH₃-SCO). The valence state, morphology and dispersion of Ag species can significantly affect the catalytic performance of Ag/γ-Al₂O₃. Herein, by using a number of surface-science measurements and density-functional theory (DFT) computation, we revealed that the terminal hydroxyl groups on the γ-Al₂O₃ surface are responsible for anchoring the Ag species. Hence, the presence of abundant terminal hydroxyl groups on nano-sized γ-Al₂O₃ surface can lead to remarkable single-silver-atom dispersion, thereby resulting in markedly higher performance than found with Ag clusters on micro-sized γ-Al₂O₃.  (ACS Catalysis, 2018, 8, 2670; ACS Catalysis, 2019, 9, 1437; Nat. Commun., 2020)
