摘　　要：采用微波辅助均相沉淀法成功制备了粒径约为 1 4nm ,比表面积高达 1 50m2 g的纳米Fe -P -O催化剂 ,并用TG -DTA、XRD、TEM等技术对其制备过程进行了考察。初步的催化研究表明 ,其对乳酸选择氧化生成丙酮酸的催化活性明显优于通常方法制备的大颗粒Fe-P -O催化剂。Nanosized Fe-P-O catalyst with average size of 14 nm and surface area of 150 m^2/g was prepared for the first time by homogenous precipitation under microwave heating.The formation process and structure were studied by TG-DTA, XRD, TEM and BET techniques.The primary studies showed that the nanosized Fe-P-O paticles possess much better catalytic activities for the selective oxidative dehydrogenation of lactic acid to pyruvic acid than the common catalyst prepared via general method.
