Problems solved by technology

However, the existing photocatalytic treatment methods for heavy metals and organic pollution still have low treatment efficiency, mainly due to the insufficient photocatalytic activity and poor stability of existing photocatalysts.
In addition, the photocatalysts used in the prior art have disadvantages such as complicated preparation process, long time consumption, and secondary pollution to the environment.

Description

technical field [0001] The invention belongs to the field of visible light catalysis, and relates to a method for treating heavy metals and organic pollutants by using a zero-dimensional black phosphorus quantum dot / one-dimensional tubular carbon nitride composite photocatalyst. Background technique [0002] In recent years, news of "super bacteria" has frequently jumped into people's field of vision, making people realize that it is imminent to solve the problem of antibiotic sewage pollution. Certain microorganisms and plants secrete certain metabolites during their metabolism, which can inhibit the growth of surrounding organisms and even cause them to die. People call such metabolites vividly antibiotics. The discovery and application of antibiotics have successfully saved the lives of countless people and ensured the economic benefits of many livestock and aquatic organisms. However, the long-term abuse of antibiotics will also endanger the environment and human health....
