摘要: 随着世界的发展和进步，我国环境废水的排放已成为环境污染的主要原因之一，威胁着国民生活和安全，亟待开发新型高效的脱除方法和材料。杂多酸(POM)是一种环境友好型催化剂，反应后无污染物，杂多酸光降解催化的效果好，从而普遍地应用于各个科研领域。本文围绕使用共沉淀法合成一种新型杂多酸催化剂H7CoIIW11039SnIVOH，与半导体催化剂二氧化钛(P25)的复合，利用罗丹明B溶液和甲基橙溶液作为有色染料，对比加入两种催化剂的量的不同，对杂多酸和P25相互掺杂催化效果进行研究，运用SEM、XRD和IR等表征手段对杂多酸和复合催化剂的外貌、结构、性质等进行表征分析。研究表明当杂多酸和P25掺杂比例为1:1时，光照下降解染料的反应活性最优。
Abstract: With the rapid development of the world, the discharge of environmental wastewater has become one of the main causes of environmental pollution, threatening people’s lives and safety. It is urgent to develop new and efficient removal methods and materials. Polyoxometalatate acid (POM) is an environmentally friendly catalyst with high catalytic activity. A lot of researches show that POM can be widely used in various reactions because of the acidity and catalytic activity. Here, we revolve around the use of co-precipitation to synthesize a new type of heteropoly acid catalyst H7CoIIW11039SnIVOH, compounded with the semiconductor catalyst titanium dioxide (P25). Rho-damine B solution and methyl orange solution are used as colored dyes, and the difference in the amount of the two catalysts added is compared to study the catalytic effect of heteropoly acid and P25 inter-doping. Characterization methods such as SEM, XRD and IR were used to characterize and analyze the appearance, structure and properties of heteropolyacids and composite catalysts. It shows that when the heteropoly acid and P25 doping ratio is 1:1, the reaction activity of degrading dyes under light is the best.
