摘要
基于π-π非共价掺杂的原理,采用半封闭高温烧结法制备了GO/g-C3N4。结构分析表明,GO与g-C3N4发生了相互作用。考察了GO引入前后g-C3N4在低光照强度下紫外光降解甲基橙的光催化活性。结果表明,掺杂适量的GO能够提高g-C3N4的光催化活性,当烧结温度为500℃、GO掺杂量为0.5wt%,热解温度为500℃时光催化降解率最高,达到39.50%。
Graphite oxide （GO） doped C3N4 was composed by semi - closed method based on π-π stacking interaction between GO and g-C3N4. The structural analysis results proved the π-π stacking interaction. The photocatalytic activities of g-C3N4 before and after GO modification were compared after composed with PVDF membranein low light intensity. The results showed that photocatalytic activity of g-C3N4 can be improved by doping right amount of GO, the photodegradation rate of GO/g-C3N4 reached its maximum value 39.50% at 0.5wt% GO and 500 ℃, for the MO photodegradation.
