研制出了可室温催化氧化甲醛的Pt/TiO₂催化剂，该催化剂不需要任何外加能量，常温常压下就能将甲醛完全催化分解为H₂O和CO₂，无副产物产生，且具有良好的耐久性。与传统甲醛氧化催化剂和甲醛氧化剂相比，这种Pt/TiO₂催化剂在国际上首次实现了甲醛气体的室温催化氧化。阐明了Pt的高度分散是Pt/TiO₂催化剂具有室温高效催化氧化甲醛特性的关键因素，并明确了贵金属催化剂室温催化氧化甲醛的反应机理。(Catal. Commun., 2005, 6, 211; Appl. Catal. B, 2006, 65, 37; Catal. Today, 2007, 126, 345)

2. 碱金属添加和高温还原处理显著提高催化剂性能

发现碱金属对Pt/TiO2室温催化氧化甲醛活性显著的助催化作用，在苛刻的反应条件下，Pt/TiO2室温下甲醛的转化率仅为20%，而含碱金属的Pt/TiO2催化剂室温对甲醛的转化率为100%。同时揭示该助促进作用是碱金属添加促进了Pt在载体表面的原子级分散，开启了室温催化氧化甲醛的新途径。(Angew. Chem. Int. Ed., 2012, 51, 9628）

进一步研究发现碱金属的促进作用普适于Pd/TiO2和Ir/TiO2催化剂体系。碱金属添加能显著促进催化剂对氧气和水的活化，因此显著提高了Pd基和Ir基催化剂室温催化氧化甲醛性能；同时，进一步阐明了氧气和水在催化剂室温氧化甲醛反应过程中具有协同作用。(Environ. Sci. Technol., 2014, 48, 5816; Catal. Sci. Technol., 2016, 6, 2289; Catal. Today, 2017, 281, 412; ACS Catal., 2018, 8, 11377)

发现高温还原处理对Pd/TiO2催化剂室温氧化甲醛具有促进作用。揭示了高温还原处理促进Pd分散的反常现象，阐明了高温处理过程中载体产生的氧空位在氧化甲醛反应过程中活化水和氧的重要作用，为制备高分散的负载贵金属催化剂提供了新思路。(Appl. Catal. B, 2017, 217, 560)

3. 常温催化净化甲醛技术产业化

实现了常温催化净化甲醛技术的产业化应用，设计组建了室内甲醛净化功能组件和空气净化器。该新型甲醛空气净化器具有高效、耗能低、安全、使用寿命长以及没有二次污染等优势，各项指标均优于传统净化技术的空气净化器，新技术空气净化器已经取得了较好的经济和社会效益。该技术早在2008年就已应用和服务于第29届奥林匹克运动会，贺泓研究员为此获得“科技奥运先进个人”称号。该成果获中国专利优秀奖和2011年国家发明二等奖。

研发了一系列低温性能优异的Pd基（Pd/AC、Pd/Al₂O₃、Pd/Co₃O₄等）催化剂，实现了苯系物的高效净化。其中，Pd/AC催化剂具备优异的吸附和催化苯系物性能，建立了常温吸附-高温原位催化氧化协同去除苯系物的新方法，该方法将传统去除低浓度VOCs的“吸附-脱附-氧化”简化为“吸附-原位氧化”过程。Pd基催化剂中金属态Pd⁰催化氧化苯系物的活性往往高于氧化态的Pd；经H₂或者NaBH₄还原处理后，Pd均被还原为金属态Pd⁰，从而提高了对苯系物的催化氧化性能。以三维介孔结构的Co₃O₄为载体合成Pd/Co₃O₄催化剂，有利于活性中心Pd的分散，提高了低温催化氧化苯系物活性。为了降低成本，我们也开展了不同形貌CeO₂催化氧化苯系物的研究，发现CeO₂纳米材料具有与贵金属相媲美的高活性，并揭示了CeO₂氧空位在苯系物催化氧化中的关键作用。以上成果为低温高效、低成本的苯系物净化催化剂研发提供了新思路。(Appl. Catal. B, 2013, 142-143, 72; Catal. Sci. Technol., 2016, 6, 4840; Sci. Rep., 2017, 7, 12845）

2. 非热等离子体–催化协同去除苯系物

开展了非热等离子体-催化协同去除苯系物的研究，发现不同锰前躯体制备的系列Mn/Al催化剂的存在大大提高了苯系物的转化率和CO₂的选择性，有效抑制了等离子体放电过程中O₃和NOx副产物的产生。其中，以醋酸锰为前驱体制备的催化剂促进作用最为显著。(Chem. Eng. J., 2016, 288, 406; J. Phys. Chem. C, 2016, 120, 6136)

3. 苯系物电催化氧化

首次将气固相电化学氧化法用于室内空气苯系物室温净化。采用膜电极组装的全固体电解池，外加2V的电压条件下即可将气态苯系物氧化为COx (CO₂、CO) 和水，CO₂选择性超过85%。通过检测发现，水蒸气在电极表面放电产生的羟基自由基(·OH )是诱导苯系物氧化的活性物种。该方法可以氧化消除多种苯系物，因此具有广谱性和应用前景。该方法的提出为室内气体苯系物的消除提供新思路。(Chem. Eng. J., 2018, 354, 93; Chemosphere, 2019, 217, 780)
