Photocatalytic Performance and Mechanistic Research of ZnO/g-C₃N₄ on Degradation of Methyl Orange

Abstract

Highly dispersed ZnO/g-C3N4 composites with different doping ratios of g-C3N4 were prepared by a hydrothermal method. The preparation method is simple and the energy consumption is low. The composite samples were used to degradate the methyl orange solution. They all showed excellent photocatalytic activity and cycling stability. The optimal loading content of g-C3N4 was investigated, and the mechanism of enhanced photocatalytic activity was studied in detail. This study provides a promising photocatalytic material for the removal of organic pollutants.

Sunlight-assisted degradation of textile pollutants and phytotoxicity evaluation using mesoporous ZnO/g-C3N4catalyst

“…According to previous reports, g-C 3 N 4 nanosheets were synthesized by a facile thermal polycondensation of melamine with some modifications. 37 In a conventional synthesis procedure, 5 g of melamine was placed in a closed silica crucible with a cover and heated at 550 °C for 4 h at a heating rate of 5 °C min −1 in a muffle furnace. After allowing cooling naturally, using a mortar and pestle, the yellow precipitate was ground into a fine powder and used without further treatment.…”

A Comprehensive Review of Graphitic Carbon Nitride (g-C3N4)–Metal Oxide-Based Nanocomposites: Potential for Photocatalysis and Sensing

“…The prepared hybrid structure can improve the electrons holes separation and efficiency [483]. Other metal oxides can also be used in the g-C3N4 Methylene Blue (MB), Methylene Orange (MO), and Rhodamine B (RhB) are the most commonly stable dyes in water at room temperature [461][462][463][464][465][466][467][468]. MB and RhB are toxic dyes that their high concentration can be so harmful to human and marine animal health.…”

Synthesis Europium (Eu3+) Doped Zinc Oxide Nanoparticles via the Co-Precipitation Method for Photocatalytic Applications

“…Industrial pollutants found in the environment particularly in the air and water pose serious health hazards to human life [1][2]. Hence, developing an elegant method to control water pollution consider a top priority in current research.…”

“…Nanomaterials, especially metal oxides have received considerable attention over the last few years due to their distinguished performance and potential applications in various fields [1]. Among these, Zinc oxide nanoparticles have been widely used in the photocatalysis field [1][2][3]. They have attracted wide attention in this area due to their unique structural and functional properties which are utilized for potential applications in energy, environmental nanotechnology, and photocatalysts to convert harmful and toxic organic pollutants into harmless elements [1][2][3][4][5][6].…”
