摘要:
在水溶液体系中,以化学还原法制得Ni-B非晶态合金纳米颗粒.应用循环伏安法,研究碱性介质中Ni-B非晶态合金纳米粉末微电极上丙醇的电催化氧化,并运用稳态极化曲线测定Ni-B非晶态合金纳米粉末微电极上丙醇的电催化氧化动力学参数.结果表明,Ni-B非晶态合金纳米粉末微电极对碱性溶液中丙醇的氧化具有很高的电催化作用.碱性介质中的Ni-B非晶态合金纳米粉末微电极上,丙醇的电催化氧化速率明显高于高择优取向(220)的镍电极.
Abstract:
Ni-B amorphous alloy nanoparticles were prepared by chemical reduction with KBH4 in aqueous solution.Electrocatalytic oxidation of propanol at the nano Ni-B amorphous alloy powdermicroelectrodes in alkaline media was studied by using cyclic voltammetry.The kinetic parameters of electrocatalytic oxidation of propanol at the nano Ni-B amorphous alloy microelectrode in alkaline media were determined with the steady polarization curves.It is found that the nano Ni-B amorphous alloy microelectrode has very strong electrocatalytic activity for the oxidation of propanol.The rates of electrocatalytic oxidation of propanol at the nano Ni-B amorphous alloy microelectrode in alkaline media are much higher than those at the highly preferred orientation(220) nickel electrode
