多相催化




一種空氣過濾器，它利用低溫氧化催化劑，在室溫下將一氧化碳轉化成毒性較小的二氧化碳下，它也可以從空氣中除去甲醛。





乙烯在固相气相界面上的加成反应


多相催化(英语：Heterogeneous catalysis)指在两相（固-液、固-气、液-气）界面上发生的催化反应，目前工业中使用的催化反应大多属于多相催化。


在化学中，多相催化是指催化剂的形式，其中催化剂的相不同于反应物的相。这里的相不仅指固体，液体，气体，而且也指不混溶的液体，例如， 油和水。绝大多数实际的多相催化剂是固体，而绝大多数反应物是气体或液体[1]。在化学和能源行业的许多领域，多相催化是至关重要的。多相催化吸引了1936年的弗里茨·哈伯(Fritz Haber)和卡爾·博施](Carl Bosch)，1932年的歐文·朗繆爾(Irving Langmuir)，和2007年的格哈德·埃特尔(Gerhard Ertl)荣获诺贝尔奖[2][3][4][5][6]。
