摘要:

隨著經濟快速發展，人類活動產生的揮發性有機物（volatile organic-compounds,VOCs）不僅會破壞大氣環境，還會嚴重危害人體健康。在治理VOCs廢氣的典型技術中，吸附法、等離子體法、催化燃燒法、光催化氧化法等均具有良好的應用前景。材料性能是影響VOCs治理效率的關鍵因素，不同的技術原理使材料制備和優化方向存在差異，如吸附法需重視所選材料的孔道結構等與VOCs分子尺寸、性質的關系；等離子體法要強化催化劑與等離子體的協同作用；催化燃燒法涉及材料的氧化還原能力；光催化氧化法則是材料對光能的有效轉化能力等。所以，明確各類技術中所用功能材料的改進重點，才能為相關材料的設計提供思路，大幅改善VOCs消除的效率。最后，對用于VOCs消除的材料研發提出了更高要求，包括具有良好抗中毒性能的材料、可協同消除多組分污染物的材料、取長補短的組合技術以及資源化利用技術。

Abstract:

With the rapid economic development, volatile organic compounds (VOCs) come from human activities will not only cause damage to the atmosphere, but also seriously be harmful to human health. Among the typical technologies of VOCs removal, the promising prospects will appear in application of adsorption method, plasma method, catalytic combustion method and photocatalytic oxidation method. The performance of applied materials is the core of the efficiency for VOCs removal. However, the preparation and modification of optimal materials will be determined by technology principles, such as adsorption method should pay attention to the relationship between the pore structure of materials and the size and properties of VOCs; plasma method will strengthen discussion on the synergistic effect of catalysts and plasma; the redox ability of catalysts is involved in catalytic combustion method; the key of photocatalytic material is the ability of effective conversion of light energy. Therefore, it is important to clarify the improved strategies of functional materials used in various technologies, which can provide new ideas of the catalysts design and greatly enhance the efficiency of VOCs elimination. Moreover, the higher demand is put forward recently, including the materials that are anti-poisoning or simultaneously eliminate multi-component pollutants, the win-win combination technologies, and a resource-utilization method.
