Research on the Preparation and Environmental Protection Application of Photocatalysts
In response to the difficulties in recycling,assembly,and poor stability of traditional photocatalysts,high-performance copper mesh based CeO2/Cu2O/Cu photocatalysts were prepared.The X-ray diffraction(XRD),photocatalytic activity,free radicals,and cycling experiments of the photocatalysts were tested to analyze their application prospects in air pollution control and provide theoretical basis for actual air pollution.The research results indicate that copper mesh based CeO2/Cu2O/Cu photocatalysts have strong degradation effects and high mineralization rates,and strong cyclic degradation ability,with only a 4.1%decrease in mineralization ability and a 5.5%decrease in xylene removal ability after 10 cycles of photocatalytic degradation.At 140 minutes of air pollution control testing,xylene and formaldehyde were basically degraded,and at 160 minutes,all three pollutants were degraded and the improvement effect was significant.
