Study on environmental purification technology for synthesis of NiO supported YMnO3 photocatalyst by two-step method

本文采用传统的溶胶凝胶法和负载法合成了NiO负载的YMnO3光催化剂。XRD结果表明,采用两步法成功合成了NiO负载的YMnO3光催化剂。紫外可见吸收光谱分析表明,NiO负载的YMnO3光催化剂具有较强的紫外可见光催化活性。通过紫外可见光催化活性研究表明,NiO负载的YMnO3光催化剂具有极好的可见光催化活性,其最佳的染料浓度为2 mg/L。

In this paper,the photocatalyst of YMnO+supported by NiO was synthesized by traditional sol-gel method and supported method.XRD results show that NiO supported YMnO+photocatalyst was successfully synthesized by two-step method.UV-visible absorption spectrum analysis shows that NiO supported YMnO+photocatalyst has strong UV-visible photocatalytic activity.Photocatalytic experiment shows that NiO supported YMnO+photocatalyst have excellent visible photocatalytic activity,and the optimal dye concentration was 2 mg/L.
