Formaldehyde is one of the vital chemicals produced by industries, transports, and domestic products. Formaldehyde emissions adversely affect human health and it is well known for causing irritation and nasal tumors. The major aim of the modern indoor formaldehyde control study is in view of energy capacity, product selectivity, security, and durability for efficient removal of formaldehyde. The two important methods to control this harmful chemical in the indoor environments are photocatalytic oxidation and catalytic oxidation with noble metals and transition metal oxides. By harmonizing different traditional photocatalytic and catalytic oxidation technologies that have been evolved already, here we give a review of previously developed efforts to degrade indoor formaldehyde. The major concern in this article is based on getting the degradation of formaldehyde at ambient temperature. In this article, different aspects of these two methods with their merits and demerits are discussed. The possible effects of operating parameters like preparation methods, support, the effect of light intensity in photocatalytic oxidation, relative humidity, etc. have been discussed comprehensively.

光催化和催化氧化消除甲醛的研究进展

甲醛是工业,运输业和国内产品生产的重要化学物质之一。甲醛释放会对人体健康造成不利影响,众所周知,甲醛会引起刺激和鼻部肿瘤。现代室内甲醛控制研究的主要目的是考虑到能源容量,产品选择性,安全性和有效去除甲醛的耐久性。在室内环境中控制这种有害化学物质的两种重要方法是光催化氧化和贵金属和过渡金属氧化物的催化氧化。通过协调已经发展起来的不同的传统光催化和催化氧化技术,在这里,我们对以前开发的降解室内甲醛的努力进行综述。本文的主要关注点在于在环境温度下降解甲醛。在本文中,将讨论这两种方法的不同方面以及它们的优缺点。全面讨论了操作参数(如制备方法,载体,光强度在光催化氧化中的作用,相对湿度等)的可能影响。
