Nano ZNO and surface modification ZNO with graphite oxide deposition to enhance the catalytic activity

Abstract

Preparation of ZnO nanoparticles and surface modification ZnO with the carbon material graphite oxide, were synthesized. The synthesized materials were characterized by PXRD, FT-IR, and UV-visible analysis. The materials show better optical and structural properties, which are beneficial in the photocatalytic degradation studies. Under light, zinc oxide and graphite oxide were used to degrade the methyl orange solution. The prepared materials by sol-gel preparation showed enhanced catalytic activity in the photocatalytic activity of methyl orange. An optimal loading content of graphite oxide was investigated. The enhanced photocatalysis was studied in detail. The study provides a promising application for the photocatalytic degradation of organic pollutants in photocatalysis. In the present work, the authors included the new novel materials of ZnO. The ZnO is modified with the surface deposits of rGO. The combined materials of semiconductor materials show a better response to light for the degradation studies. The use of such a combination is a new study and the results reflect the modification of semiconductor materials in the p-block elements such as C, N, F, P and so on for the enhanced photocatalytic applications of semiconductor mediated materials, which are widely used in photocatalysis. The PXRD analysis of ZnO and rGO shows better crystallinity in the case of ZnO, whereas after the deposition of rGO, crystallinity is lost due to the overlap of the main base material semiconductors, which explains the new catalytic and recombination effects of the materials used.
