能源与社会发展密切相关,氢能是一种清洁无污染的能源,利用光催化制氢技术成为解决能源问题的一种有效途径.为了丰富实验教学内容,本文将科研引入到实验课程,设计了利用简单的高温热聚合法制备氮掺杂氮化碳并使用光化学合成方法将镍硫化物负载其表面来制备光催化复合材料并对其进行光催化分解水产氢性能研究的综合实验.采用X射线衍射、X射线光电子能谱等对材料的物相结构和表面元素价态进行表征,并且通过紫外-可见漫反射光谱和光致发光光谱分析了材料的光吸收能力和光生载流子的复合情况.另外,也研究了可见光下该材料光催化分解水产氢性能.通过该实验提高了学生的综合实验素质,也激发了学生的创新思维.
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.
