Abstract

Abstract: Cadmium tungstate (CdWO4 ) photocatalyst was successfully fabricated with flower like nanosheets-assembly (FNA) by modified hydrothermal method. The as-synthesized nanostructures were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), BET surface area analysis, Fourier Transform Infrared spectroscopy (FTIR) and Photoluminescence (PL). The photocatalytic degradation performance of FNA was explored for two model dyes, Congo red (CR) and methyl orange (MO), under visible light irradiation while hydrogen absorption features were also studied at three different temperatures. Slight difference in degradation rate constants is observed for CR and MO dyes i.e. 0.0262 min -1 and 0.0517 min -1 respectively. Catalyst dose concentration of 0.1g/L has shown maximum degradation efficiency for dyes. Hydrogen storage capability reaches to 1.87 wt% at 573K when CdWO4 FNA is used.
