Abstract
Introduce a comprehensive chemical experiment-graphite-phase carbon nitride(g-C3N4),as a new non-noble metal visible light catalyst,can photolysis hydrogen in aquatic products by solar energy,and has been widely used in hydrogen energy development.However,due to its limited light absorption capacity,photogenerated electron-hole recombination and other shortcomings,the photocatalytic performance is low.In this paper,the NiFe/g-C3N4 composite was synthesized by hydrothermal method using urea as precursor,and then NiFe alloy was pre-pared by hydrothermal method,it was characterized by x-ray diffraction(XRD)and energy dispersive spectrometer(EDS),and its hydrogen production was tested by water and triethanolamine.The results show that the hydrogen production efficiency of g-C3N4 compound with a certain amount of alloy is improved,and the efficiency of NiFe/g-C3N4 compound with a mass fraction of 25％is 84 times higher than that of pure g-C3N4.The combination of NiFe alloy with g-C3N4 weakens the photoelectron hole recombination and enhances the photocatalytic activity.关键词
