Study on Photocatalytic Technology with Photovoltaic-Thermal Integration and its Applications in Indoor Air Purification

In terms of energy and environmental purification, application of photocatalytic purification in energy and environment is getting increasingly widespread. In the present paper, it focused on the applications of photocatalytic technology in indoor air purification. Photocatalyst and photocatalytic reaction devices are the two issues in photocatalytic air purification. Fe-La co-doped TiO2 was prepared, and integration of photovoltaic-thermal circular photocatalytic air purification reactor was designed, which showed high air purification efficiency. The experimental data and theoretical analysis gave the support to exploit new indoor air purification technologies. Further, technical and economic analysis on photocatalysis technology with photovoltaic-thermal integration applying in indoor air purification was studied and helpful results were attained.
