摘要
为提高木质素利用率,减少环境污染,以三聚氰胺、双氰胺、硫脲为前驱体,采用热聚合法合成石墨相氮化碳(g-C3N4),并通过控制变量,观察不同前驱体制备的g-C3N4在可见光照射下的光催化重整木质素制氢性能,以期获得能够用于工业化重整生物质制氢的高效、廉价光催化材料。
In order to improve the utilization rate of lignin and reduce environmental pollution,Graphitic carbon nitride(g-C3N4)photocatalysts were prepared from different precursors(melamine,dicyandiamide and thiourea)via a simple thermal polymerization method.The photoreactivities of as-obtained g-C3N4 samples were evaluated by photocatalytic reforming of lignin for H2 production under visible-light irradiation by controlling variables,which could help obtain efficient and cheap photocatalytic materials for hydrogen production from industrial reforming biomass.
