Nanoparticles have been used in heterogeneous catalysis in the petrochemical industry for selective hydrogenation and oxidation reactions for many years, and it has long been realized that metallic nanoparticles can used to improve the sensitivity and selectivity of solid-state gas sensors. My long-term research objective is to develop highly selective and ultra-sensitive nanoparticle catalysts and sensors through the control of the size, shape, structure, and composition of nanoparticles, and precisely controlling the nanostructural and microstructural ordering of the nanoparticles within high-surface area solid-state supports. This work will be important for the development of highly efficient industrial catalysts which give minimal undesired products, as well as solid-state sensors which can detect trace amounts of toxic gases in the atmosphere.

纳米颗粒在石化工业中用于选择性加氢和氧化反应的多相催化已有多年，并且很早就认识到金属纳米颗粒可以用来提高固态气体传感器的灵敏度和选择性。我的长期研究目标是通过控制纳米颗粒的尺寸、形状、结构和组成，并精确控制高表面纳米颗粒的纳米结构和微观结构有序性，开发高选择性和超灵敏的纳米颗粒催化剂和传感器。区域固态支持。这项工作对于开发能够产生最少不良产物的高效工业催化剂以及能够检测大气中微量有毒气体的固态传感器非常重要。
