疏水催化剂应用进展

疏水催化剂主要用于反应物、产物或反应介质中有水的一些反应，包括氢-水液相催化交换、氢氧复合、有机物的低温氧化、NO_x选择催化还原和含NH₃废水的处理等。文章对疏水催化剂在各领域的应用进展进行综述，并对其催化特点及存在问题进行讨论。反应在室温或略高于室温的条件下进行，能耗低；对一些反应，疏水催化比亲水催化有更高选择性。针对具体的反应，研究疏水催化剂制备工艺，提高疏水催化剂对具体反应的催化性能有利于其工业上广泛应用。

Application Progress of Hydrophobic Catalyst

Hydrophobic catalysts are used in some reactions in which one of reagents, products,or reaction medium is water,including hydrogen-water liquid catalytic ex- change,recombination of H_2-O_2,oxidation of organic compounds at low temperature, selective catalytic reduction of NO_x,removal of NH_3 in wastewater,and so on.Applica- tion progress of hydrophobic catalyst was reviewed in above fields,then its catalytic characters and some questions of applications were discussed.The reactions are carried at room temperature or slightly above room temperature and have low energy consump- tion.Hydrophobic catalysis has higher selectivity than hydrophilic catalysis for some re- actions.The fabrication methods of hydrophobic catalysts are similar to those of hydro- gen-water liquid catalytic exchange reaction in all reactions.They are favorable for wide applications of hydrophobic catalyst in industry,to study fabrication methods of hydro- phobic catalyst and enhance catalytic activity for specific reaction.
