Abstract
? 2022 Elsevier B.V.It is well known that the enhanced photocatalytic performance of graphite-type carbon nitride (g-C3N4) will be limited by its microstructure, including its precursor structure, and the relationship between the precursor structure and the target catalyst structure will be an interesting question. Glutaraldehyde (GA) containing aldehyde group was introduced into melamine (MA) to form three GA/MA precursors connected by C[dbnd]N chemical bond, which cause the calcined composite catalysts of g-C3N4 and C with closer lamellar structure along with the increase of the amount of glutaraldehyde added. The study found that the C[dbnd]N chemical bond limits the conversion of melamine to melem by thermal decomposition kinetics analysis, which leads to the formation of the tighter interactions by carbonization. The resulting structure has more efficient photocatalytic performance than pure g-C3N4.
