Abstract

Abstract

The arid plateau regions， characterized by their unique climatic conditions such as intense ultraviolet radiation， low humidity， high wind speeds， and frequent sandstorms， impose extremely high demands on the durability and self-cleaning properties of materials. In recent years， catalytic self-cleaning materials have garnered significant attention due to their potential in environmental purification and energy efficiency enhancement. These materials achieve self-cleaning through photocatalytic reactions and their unique surface wettability properties. However， their traditional applications often rely on the presence of water， which somewhat limits their suitability in arid regions. To address this issue， this study employed a hydrothermal method to prepare a superhydrophilic titanium dioxide （TiO₂） coating， with a focus on investigating its photocatalytic activity， UV resistance， and anti-static properties. Field tests were conducted in plateau arid regions to evaluate its performance. The experimental results demonstrated that the coating effectively removed contaminants from the surface of photovoltaic panels， significantly improving power generation efficiency. Specifically， the coating achieved a formaldehyde removal efficiency of up to 91.4% and an inhibition rate of 97.71% against Escherichia coli. In practical applications in southwestern regions， the power generation efficiency of photovoltaic systems increased by 4% to 6%， with a maximum improvement of 18.16%. In desert regions， the efficiency also saw an enhancement of 2.11%. These results clearly indicate that the catalytic self-cleaning coating exhibits excellent stability and durability under various environmental conditions， demonstrating broad application prospects.
