Comprehensive Experiment of Synthesis of NiSx/Nitrogen-doped g-C3N4 and the Photocatalytic Properties towards Photocatalytic Hydrogen Production
Energy is closely related to the development of society,and hydrogen energy is a clean and pollution-free energy source,and the use of photocatalytic hydrogen production technology has become an effective way to solve the energy problem.To enrich the experimental teaching contents,scientific research was introduced into the experimental course.A comprehensive experiment was designed to prepare nitrogen-doped carbon nitride by a simple high-temperature thermal polymerization method,on which nickel sulfide was loaded photochemically to form a composite material for photocatalytic water splitting to produce hydrogen.X-ray diffraction and X-ray photoelectron spectroscopy were used to characterize the phase structure and elemental valence of the materials on the surface.The light absorption ability and photogenerated carrier recombination were analyzed by UV-Vis diffuse reflectance spectroscopy and photoluminescence spectroscopy.In addition,the performance of hydrogen production under visible light was also investigated.The experiment has improved the comprehensive ability of the students on doing experiment was improved and their innovative thinking was stimulated.
