摘要
以氯化铁、氯化钠和碳酸钠为原料通过共沉淀法合成羟基氧化铁(FeOOH)纳米棒,采用管式加热炉焙烧并通入H_(2)/Ar混合气进行还原反应,再通过浸渍法将钯单原子负载在FeOOH纳米棒上,合成了钯单原子负载FeOOH纳米棒(Pd_(1)/FeOOH),并对其结构进行了表征。以甲基二苯基硅烷为模型化合物,研究其有机氧化催化反应活性,结果表明该催化剂对甲基二苯基硅烷的氧化反应具有较好的催化性能,t=15 min,甲基二苯基硅烷氧化反应转化率为99%,产物甲基二苯基硅醇的选择性为99%,转化频率(TOF)为6820 h^(-1)。
FeOOH nanorod was synthesized by FeCl 3,NaCl,and NaCO 3 through precipitation method.The FeOOH nanorod was treated in a tube furnace with H_(2)/Ar for reduction reaction,single palladium atom stabilized by FeOOH nanorod(Pd_(1)/FeOOH)was prepared by impregnation route.The structure was characterized.Methyldiphenylsilane was chosen as a model compound to investigate the oxidation performance of the Pd_(1)/FeOOH.This single palladium atom catalyst manifests outstanding catalytic efficiency in the oxidation of silane to silanol in 15 min,the methydiphenylsilane conversion is 99%,the methydiphenylsilanol selectivity is 99%,and the turnover frequency is 6820 h^(-1).
