| 摘 要： | 采用溶剂热法制备了金属有机框架材料MOF(Ni)-74及其与氧化石墨烯(GO)的复合材料MOF(Ni)-GO,并利用线性伏安扫描(LSV)等电化学方法在N_2饱和的0.5mol/L H_2SO_4溶液中对材料的电催化性能进行了检测。实验结果表明,GO的掺杂能显著提升金属有机框架材料MOF(Ni)-74的电催化活性。其中GO含量为8%时,所得复合材料表现出最好的电催化析氢活性,起始电势仅为-0.462V,塔菲尔斜率为110mV/dec,同时该材料也表现出很好的电化学稳定性。

| Abstract: | Using a solvothermal method, the metal-organic framework MOF(Ni)-74 and a series of its derivatives MOF(Ni)-GO(w%) differing in graphene oxide (GO) content (w%) were synthesized, and subsequently the linear sweep voltammetry (LSV) test was conducted in a N2-saturated 0.5 mol/L H2SO4 solution in order to determine the electrocatalytic performance of the products to hydrogen evolution reaction (HER). Our experiment confirmed the significantly improved electrocatalytic activity of the GO-decorated MOF(Ni)-74 catalysts, among which the MOF(Ni)-GO(8%) exhibited the best electrochemical catalytic performance towards HER with the lowest onset potential (-0.462 V), the smallest Tafel slope (110 mV/dec), as well as an excellent electrochemical stability. |
