Synthesis and Characterization of Silver Vanadate and Graphitic Carbon Nitride Composites

Abstract:

Various silver vanadate and graphitic carbon nitride (AgVA/g-C₃N₄) composites with different weightage of 10 wt%, 30 wt% and 50 wt% of AgVA were synthesized using wet chemical method and the prepared samples were named as A10, A30 and A50. Based on SEM analysis, the synthesized pure g-C₃N₄ exhibited a two-dimensional structure with typical irregular porosity whereas pure AgVA had a rod-like shape. The diffraction peaks of both g-C₃N₄ and AgVA could be observed in the composites, indicating that AgVA had been successfully coupled with g-C₃N₄. The stretching vibration of V-O was found in in pure AgVA and all composites. EDX analysis confirmed the presence of C, N, Ag, V and O element in the prepared composites. A10 was found to possess a larger BET specific surface area, smaller particle size and larger pore volume compared to that of pure g-C₃N₄.
