摘要
以还原黄GCN为原料,采用还原氧化-水热法制备纳米有机光催化剂GCN。以甲基橙作为目标降解物,研究了水热时间和水热温度对光催化剂GCN光催化降解性能的影响。结果表明,可见光照射60min后,光催化剂GCN对甲基橙的降解率可达87.95%,经过3次循环使用后,仍保持较好的光催化活性,超氧自由基(·O_(2)-)为光催化降解过程的主要活性物质。
A nano organic photocatalyst GCN is prepared by a reduction oxidation-hydrothermal method using Vat Yellow GCN as raw material.The effects of hydrothermal time and temperature on the photocatalytic degra⁃dation property of GCN photocatalyst are studied using Methyl Orange as the target product.The results show that the degradation rate of Methyl Orange by the photocatalyst GCN reaches 87.95%after 60 min visible light irradiation,and it still maintains good photocatalytic activity after three cycles.Superoxide free radicals(·O_(2)-)is the main active substances in the photocatalytic degradation process.
