研究方向

(1) 半导体氧化物表面小分子光化学研究
随着矿石能源的日益枯竭,和环境污染的日益严重,太阳能的合理高效利用是有效解决能源和环境问题的重要手段。其中,利用太阳能驱动催化反应将其转换成化学能是太阳能利用的一项重要技术。围绕此技术,人们开发出了不同种类的光催化剂,来进行相应的催化反应,比如光催化水分解,光催化生物质合成,以及光催化有害物质降解等。而在这些光催化反应进行研究的过程中,反应机理的研究却往往被忽略掉了。通过研究光催化反应中的基元反应过程,和反应过程中的涉及到的电子和能量转移,不仅能知道反应过程中的反应决速步,也能知道反应过程中电子和能量有效传递被用来驱动反应的通道。这些机理的研究为催化剂的改进和新型催化剂的合成能提供可靠的指导。
(2) CO、NO等小分子低温氧化
在一些燃料的燃烧过程中,不完全燃烧往往会产生一些有害气体,比如CO、NO等小分子,这些气体的产生会引起环境污染。因此,如何低温有效地将这些小分子完全氧化,或者是降解对燃烧,工业气体中的杂质去除,以及机车尾气的处理极为重要。所以,研究CO、NO等在氧化物表面小分子低温氧化机理为催化剂的改进和新型催化剂的合成能提供可靠的指导。
(3) 分子束表面散射
在实际催化过程中,反应往往是在高温高压下发生的。而在高温高压下,在1秒内,分子和催化剂碰撞次数大约在1023次。因此,即使分子与催化剂相互作用发生反应的概率,或者是反应截面很小。这个时候也能有效地发生反应。而对于反应机理的研究,往往都是单次碰撞反应。要有效地提高反应效率,只能去改变分子的能量,以增大反应概率。因此,可以利用分子束散射的方法去研究分子与表面之间的相互作用,以此研究其中的传能和成断键过程。进而去理解高温高压下反应过程中的基元反应。
