摘　　要：利用光催化技术将太阳能转化为化学能或应用于降解和矿化有机污染物,是目前解决能源短缺和环境污染问题的有效途径.非金属半导体材料类石墨相氮化碳(g-C_3N_4)是一类新型的可见光光催化剂,但是单一的g-C_3N_4光催化剂往往体现的光催化活性都比较低.通过合理的复合改性,将零价Fe(Fe^0)成功负载类石墨相氮化碳光催化剂,并对其可见光光催化性能进行探索.结果表明,在可见光下,相对于纯的g-C_3N_4,Fe^0/g-C_3N_4光催化剂可以有效提高对模拟燃油(100μg/g吡啶/正辛烷)的脱氮率.Utilizing photocatalysis technology to convert solar energy into chemical energy or direct degradation and mineralization of organic pollutants is a long-term solution to solve the problem of energy shortage and environmental pollution. Nonmetal-semiconductor g-C3N4 is a new visible lighted photocatalyst with the similar structure to graphene. But the photocatalytic activity of single g-C3N4 is often relatively low. In this study, the Fe（0） is successfully loaded to g-C3N4 to form composites Fe^0/g-C3N4 by simple compound modification. And also, the photocatalytic activity of Fe0/g-C3N4 was carried out under visible light. The 100μg/g pyridine/octane was used as simulation fuel. The results indicated that the photocatalytic properties of denitrification with Fe^0/g-C3N4 are better than pure g-C3N4.
