采用了热分解法合成Ni-Cr-Co氧化物纳米粒子,并用作直接甲醇燃料电池(DMFC)的阳极电催化剂。通过X射线衍射(XRD)、透射电子显微镜(TEM)和扫描电子显微镜(SEM)对催化剂进行表征,制得的纳米催化剂均匀分散,且粒径为25~50 nm。利用循环伏安法(CV)对不同金属摩尔比和焙烧温度下的催化剂在甲醇氧化反应中的活性进行了研究。结果表明,Ni-Cr-Co(摩尔比为1∶1∶1.5)的纳米氧化物对甲醇氧化反应的起始电位、峰值氧化电流密度和If/Ib分别为0.38 V,19.3 mA/cm2和1.72,表现了很好的电催化性能。 The thermal decomposition method was used to synthesize Ni-Cr-Co oxide nanoparticles and used as the anode electrocatalyst in direct methanol fuel cell (DMFC). The catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The prepared nanocatalysts were uniformly dispersed with particle size of 25-50 nm. Cyclic voltammetry (CV) was used to study the activity of the catalysts in methanol oxidation at different molar ratios of metals and calcination temperatures. The results showed that the initial potentials, peak oxidation current density and If / Ib of the nano-oxides with Ni-Cr-Co molar ratio of 1: 1: 1.5 were 0.38 V, 19.3 mA / cm2 and 1.72 , Showing good electrocatalytic performance.
