Emerging photocatalytic applications of graphitic carbon nitride

2016

Graphitic carbon nitride assisted partial photocatalytic oxidation of the biomass platform molecule 5-hydroxymethyl-2-furfural (HMF) in aqueous medium was investigated. Different carbon nitride precursors were considered, being melamine the one yielding the most efficient photocatalyst The thermal exfoliation procedure of g-C3N4 gave rise to exfoliated samples with higher specific surface areas that also showed both an enhanced photocatalytic activity in conversion of HMF, and selectivity (ca. 42-45 %) towards FDC. The utilization of radical scavengers revealed that superoxide radicals were the main reactive species responsible for HMF oxidation to FDC. The use of natural solar light result…
