Description

technical field

[0001] The invention relates to a rapid, energy-saving and high-yield material synthesis method for preparing graphite-like structure carbon nitride, which belongs to the technical field of catalytic material preparation and application. Background technique

[0002] Energy shortage and environmental pollution have become global problems restricting the sustainable development of human society. Photocatalysis can directly use solar energy to decompose water to produce hydrogen and degrade organic pollutants. It has the potential to meet the large-scale industrial use of hydrogen in the future and solve environmental pollution problems. One of the ultimate approaches to energy and environmental issues. Since the technology was discovered in 1972, developed countries in the East and the West have invested a lot of money and manpower, which has led to the rapid development of photocatalytic science.

[0003] Over the past 30 years, research on photocatalytic m...
