碳铁催化剂的研究进展

Fe_xO_y/C复合材料作为催化剂,在有机化合物的催化氧化方面表现出非常高的活性,如对苯甲醇催化氧化苯甲醛,苯乙烯催化氧化苯甲醛,苯甲醛催化氧化苯甲酸,苯催化氧化苯酚,是最高效的催化剂之一。近年来的研究报道中,Fe_xO_y/C复合材料的制备方法主要有水热合成法,浸渍法和超声喷雾热解法。比较了三种方法各有利弊,以期寻找一种更加高效,方便,省时的制备Fe_xO_y/C复合材料的方法。其中溶液燃烧法尤为重要,溶液燃烧法给Fe_xO_y/C复合材料的制备带来了新的机遇。

Research Progress of Carbon-Iron Catalysts

FexOy/C composite materials as catalysts showed very high activity for catalytic oxidation of benzyl alcohol to benzaldehyde, catalytic oxidation of styrene to benzaldehyde, catalytic oxidation of benzaldehyde to benzoic acid, catalytic oxidation of benzene to phenol, and was one of the most efficient catalyst. In recent years, the preparation methods of FexOy/C composites were described, mainly in hydrothermal method, impregnation method, ultrasonic spray pyrolysis method. Each method had advantages and disadvantages. We wanted to find a more efficient, convenient and time saving method for the preparation of FexOy/C composites. The solution combustion method was particularly important. Solution combustion synthesis had brought new opportunities for the preparation of FexOy/C composites.
