MetadataShow full item record
Controlled synthesis of efficient catalysts for CO oxidation is of great importance in various industrial and environmental applications. Herein, we developed a scalable up approach for one-pot synthesis of graphitic-like porous carbon nitride (gC3N4) nanostructures co-doped with Au and Pd as efficient catalysts for carbon monoxide (CO) conversion, based on the polymerization of melamine with nitric acid in an organic solvent in the presence of metal precursors followed by carbonization at elevated temperature. Interestingly enough, gC3N4 nanotubes and nanowires were formed using ethylene glycol and ethanol solvents, respectively. The CO oxidation performance of Au/Pd-doped gC3N4 nanotubes was superior to Au/Pd-doped gC3N4 nanowires. This is owing to the porous one-dimensional nanotube morphology, which provide various accessible active sites for the adsorption of reactant molecules. The presented method may open new frontiers on the synthesis and utilization of gC3N4 one-dimensional nanostructures in gC3N4 in gas phase reactions.
