Nano-tungsten trioxide has a wide range of applications in the field of photocatalysis, mainly including the following aspects:
Nano tungsten trioxide splitting water to produce hydrogen
As a photocatalyst, nano-tungsten trioxide can absorb visible light and ultraviolet light, and decompose water into hydrogen and oxygen through a photocatalytic reaction. This photocatalytic hydrogen production technology is considered as a sustainable and environmentally friendly energy conversion method.
Nano-tungsten trioxide photocatalytic degradation of organic pollutants
Nano-tungsten trioxide has high light absorption capacity and catalytic activity, and can be used to degrade organic pollutants in water, such as dyes, drug residues and organic solvents. It can decompose organic pollutants into harmless substances, realize water purification and environmental governance.
Nano-tungsten trioxide photocatalytic CO2 reduction
Nano-tungsten trioxide can use light energy to convert carbon dioxide (CO2) into useful hydrocarbons, such as methane and methanol. This photocatalytic CO2 reduction technology is expected to be used for CO2 emission reduction and resource efficient utilization.
Nano-tungsten trioxide photocatalytic bacteria inactivation
Nano-tungsten trioxide has antibacterial activity and can be used for photocatalytic inactivation of bacteria and viruses. Through the photocatalytic process, nano-tungsten trioxide can generate active oxygen species, such as hydroxyl radicals and superoxide radicals, thereby destroying the cell membrane and DNA structure of bacteria, and realizing the inactivation and disinfection of bacteria.
These applications show that nano-tungsten trioxide has great potential as a photocatalyst, which can be used in clean energy production, environmental protection, and medical and health fields. However, further research and optimization are still needed for practical applications to improve photocatalytic efficiency and stability.
