摘　　要：以纳米钛硅分子筛(TS-1)晶体作为复合相与镍磷合金在泡沫镍(NF)表面共沉积,制备了镍基非晶合金/钛硅分子筛复合材料(Ni-P-TS-1/NF),并采用原位处理工艺对其催化性能进行优化。催化性能测试结果表明:原位处理过的复合材料具有优异的电催化析氧性能。这是由于纳米钛硅分子筛的共沉积提升了复合材料表面的电子转移速率及电催化活性表面积,原位处理工艺改变了复合材料的表面形貌及电子状态,暴露出更多的催化活性中心,并形成了能为电催化析氧反应提供活性中心的镍的磷化物及氢氧化物,从而有效提升了复合材料的电催化析氧性能。Nickel based amorphous alloy/titanium silicalite zeolite composite(Ni-P-TS-1/NF)was prepared on the surface of nickel foam(NF)by co deposition of nano titanium silicate(TS-1)zeolite with Ni-P alloy,and its catalytic performance was optimized by in-situ treatment process.The results of catalytic performance test show that the treated composite exhibits excellent electrocatalytic oxygen evolution performance.This is due to the doping of nano TS-1 zeolite improves the electron transfer rate and electrocatalytic active surface area of the composite;the in-situ treatment process changes the morphology and electronic state of the composite surface,exposes more catalytic active centers,and forms nickel phosphide and hydroxide which can provide active centers for electrocatalytic oxygen evolution reaction(OER),therefore effectively improving the OER performance of the composite.
