Preparation method of titanium carbide composite indium-zinc sulfide photo-anode

Abstract

The invention discloses a preparation method of a titanium carbide composite indium-zinc sulfide photo-anode, wherein the preparation method comprises the following steps: a, dispersing titanium aluminum carbide in hydrofluoric acid, and repeatedly centrifuging, washing with water and drying to obtain titanium carbide microspheres; b, taking indium chloride, zinc chloride and thioacetamide as rawmaterials to prepare a hydrothermal reaction solution, adding the reaction solution and fluorine-doped stannic oxide conductive glass (FTO) into a reaction kettle, carrying out a hydrothermal reaction, and cleaning and drying after the hydrothermal reaction is finished to obtain an indium-zinc sulfide photo-anode; and c, placing the indium-zinc sulfide photo-anode in a titanium carbide solution, soaking, cleaning and drying, and thus obtaining the titanium carbide composite indium-zinc sulfide photo-anode. The obtained photo-anode is used for photoelectrocatalytic decomposition of water to produce hydrogen, and titanium carbide can increase the charge carrier density of the photo-anode and effectively enhance the photoelectric property of indium-zinc sulfide, so that the solar photo-hydrogen conversion efficiency of the semiconductor photo-anode is improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials, and in particular relates to a preparation method of a titanium carbide composite indium zinc sulfide photoanode and its application in photoelectric catalytic water decomposition. Background technique [0002] In order to realize the strategy of sustainable development, the development and utilization of renewable energy industry has become an important strategic goal of all countries in the world. Among them, solar energy, as a clean renewable energy source, has tens of thousands of times the reserves of other renewable energy sources; at the same time, solar energy hardly releases greenhouse gases during use, which helps to alleviate environmental pollution caused by extensive use of petroleum and fuel combustion. Environmental issues such as the greenhouse effect promoted by the solar energy have occupied an important position in the renewable energy industry. [0003] Due to...
