摘要
采用微波法制备了Ni／WO3玻纤光催化剂,研究了反应温度、湿度、催化剂负载量、甲醛初始浓度等条件对甲醛气体光催化降解率的影响。实验结果表明,当反应温度为38℃,反应器内湿度为40％,催化剂负载量为O．256 g(玻纤5 cm×6 cm),甲醛初始浓度为2．255 mg/m3时,甲醛降解率达到73％。
Ni/WO3/fiberglass photo-catalyst was prepared with microwave way. The effects of reaction conditions （such as temperature, humidity, catalyst loading and initial concentration） on degradation ratio of formaldehyde were investigated. The Results showed that the degradation ratio of formaldehyde reached 73%, when reaction temperature was 38℃, humidity was 40%, loading quantity was 0. 256 g （5 cm× 6 cm）, initial concentration was 2.25 mg/m^3
