Abstract

The invention relates to a photocatalyst, in particular to a conjugated polymer photocatalyst for decomposing aquatic hydrogen under visible light. Firstly, urea is heated and melted at 120-160 DEG C,then melamine formaldehyde resin is added, and stirred to form a uniform mixed solution, the uniform mixed solution is cooled to room temperature, ground, heated to 550-750 DEG C at a heating rate of3-5 DEG C / min, and calcined at 550-750 DEG C for 2-4 hours to obtain the porous nitrided carbon-based conjugated polymer photocatalyst; and the prepared porous nitrided carbon-based conjugated polymer photocatalyst is applied to study the decomposition of water to produce hydrogen under visible light.

Description

technical field [0001] The invention relates to a photocatalyst, in particular to a conjugated polymer photocatalyst that decomposes water to produce hydrogen under visible light, and uses a simple one-step calcination method to synthesize porous carbon nitride (g-C 3 N 4 )-based conjugated polymer, and the prepared porous carbon nitride-based conjugated polymer was applied to the research on the hydrogen production performance of water splitting under visible light. Background technique [0002] Hydrogen energy, as one of the "zero pollution, zero carbon, high energy, environment-friendly, and omnipotent (can be used for power generation, heating, and transportation fuel, etc.)" sustainable and clean energy, plays an important role in global energy distribution. important role. The World Hydrogen Energy Council believes that the development of hydrogen energy is crucial to realizing energy transformation and curbing global warming. At the same time, hydrogen energy can be...
