摘要
利用荧光素作为光敏剂,三乙醇胺(TEOA)作为牺牲剂,在大于420 nm的LED灯照射下,3价铁离子光催化还原生成零价铁纳米粒子分散在二维g-C_3N_4片上,并伴随着光催化分解水产氢,催化产氢效率达到5.97μmol·h^(-1).光催化反应48 h后,催化活性没有明显降低.
A stable hydrogen photogeneration system containing fluorescein as photosensitizer,TEOA as electron donor,Fe /g-C_3N_4 as catalyst,was established. In which zero-valent Fe nanoparticles was formed by in-situ photoreduction of iron（ III）. The Fe /g-C_3N_4 composite exhibits significantly enhanced visible-light catalytic performance with H_2 evolution rate of 5. 97 μmol h^（-1）.
