Abstract: An organic wastewater treatment method based on a multi-element co-doping TiO2 nano photocatalytic material includes preparing a sulfur-titanium dioxide mixture, hydrothermally reacting the sulfur-titanium dioxide mixture with copper chloride, ammonia, strong alkali, a transition metal salt and the like, reacting the resulting reaction product with hydrofluoric acid, then performing temperature programming thermal treatment in air to obtain the multi-element co-doping TiO2 nano photocatalytic material, and then treating organic wastewater with the multi-element co-doping TiO2 nano photocatalytic material under the irradiation of visible light. The organic wastewater treatment method is efficient and rapid, safe and environmental-friendly, can thoroughly degrade many types of organic pollutants, ammonia nitrogen and the like, and does not cause secondary pollution; furthermore, the adopted multi-element co-doping TiO2 nano photocatalytic material can be regenerated and recycled only by simple calcination, and the cost is inexpensive.

Abstract: A porous carbon-based metal catalyst, a preparation method and application thereof are provided. The preparation method includes: successively performing activation, surface corrosion, nitrogen-doping treatment and graphitization treatment on washed micro-grade porous carbon, then performing sensitization treatment, and subsequently carrying out loading, reduction and other treatments of catalytic metal, so as to finally obtain the porous carbon-based metal catalyst. The porous carbon-based metal catalyst provided by the present application has excellent catalytic performance, is especially suitable for producing hydrogen by efficiently catalytically decomposing ammonia borane, is not prone to inactivation, and is easy to regenerate after inactivation. Meanwhile, the preparation method is environmental-friendly, is suitable for large-scale production and has a wide application prospect in the fields such as hydrogen fuel batteries.
