Description

technical field [0001] The invention belongs to the field of photocatalysts, in particular to a transition metal-modified pyridine nitrogen-based conjugated microporous polymer composite photocatalyst. Background technique [0002] Energy and the environment are two core issues facing the world today. Human life and technological development are closely related to energy. The burning of traditional fossil fuels emits a large amount of greenhouse gases and causes serious damage to the environment. Therefore, it is urgent to find new clean energy sources. Hydrogen energy helps to solve global environmental pollution and energy security issues, so it becomes an ideal substitute for traditional energy. Among them, photocatalytic water splitting is the main path for hydrogen production, and photocatalytic technology will become an effective means to solve energy and environmental problems in the future. [0003] Conjugated microporous polymers are rigid macromolecules composed ...
