摘要

摘要: 高原干旱地区因其独特的气候条件，如强烈的紫外线辐射、低湿度、高风速以及频繁的沙尘暴，对材料的耐久性和自洁性能提出了极高的要求。近年来，催化型自洁净材料因其在环境净化、能源效率提升等方面的显著潜力，受到了广泛关注。这类材料通过光催化反应及其独特的表面湿润特性实现自清洁功能，但其传统应用通常依赖于水的参与，在一定程度上限制了其在干旱地区的适用性。针对这一问题，采用水热法制备了一种超亲水二氧化钛涂层，重点研究了其光催化活性、耐紫外线性能及抗静电特性，并在高原干旱地区进行了实地测试。结果表明：该涂层能够有效去除光伏板表面的污染物，显著提升发电效率。具体而言，涂层对甲醛的去除率高达91.4%，对大肠杆菌的抑制率达到97.71%。在西南地区的实际应用中，光伏系统的发电效率提升了4%~6%，最高可达18.16%；在沙漠地区，发电效率也实现了2.11%的提升。研究数据揭示了催化型自洁净涂层在不同环境条件下均表现出优异的稳定性和持久性，展现出广阔的应用前景。

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.
