摘　　要：甲醛是室内主要空气污染物之一,甲醛浓度超标会对人体健康造成极大的危害,降解室内甲醛刻不容缓。光催化降解甲醛被认为是一种绿色无污染的降解方法。本文中我们对光催化降解甲醛所涉及几个重要环境条件(催化剂负载量、甲醛初始浓度、相对湿度、辐照度)进行实验,通过这一系列实验不仅能帮助大家了解光催化甲醛的最佳环境条件,而且能进一步规范紫外催化光源的光催化检测条件。特别是光强一直被光催化领域所忽视,通过本实验能帮助大家得到最佳的催化光强,从而提高催化效率,降低不必要的能源消耗。Formaldehyde is one of the main indoor air pollutants.Excessive formaldehyde concentration can pose a great danger to human health.It is urgent to degrade indoor formaldehyde.Photocatalytic degradation of formaldehyde is considered a green and pollution-free method of degradation.In this article,we conducted experiments on several important environmental conditions involved in photocatalytic degradation of formaldehyde(catalyst loading,initial formaldehyde concentration,relative humidity,and irradiance).Through this series of experiments,not only the optimal environmental conditions for photocatalytic degradation of formaldehyde was obtained,but also further standardized the photocatalytic detection conditions of ultraviolet catalytic light sources.Especially,irradiance has been overlooked in the field of photocatalysis.This experiment can help you obtain the optimal catalytic light intensity,thereby improving catalytic efficiency and reducing unnecessary energy consumption.
