Research Progress of Functional Materials for VOCs Elimination
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 combus-tion 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 proper-ties 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.
