Synthesis of Rod‐Like g‐C₃N₄/ZnS Composites with Superior Photocatalytic Activity for the Degradation of Methyl Orange

Abstract

A rod-like g-C 3 N 4 /ZnS composite was synthesized via a hydrothermal process using g-C 3 N 4 , Zn(NO 3 ) 2 ·6H 2 O, thioglycolic acid, and thioacetamide as precursors under reflux conditions. The obtained products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV/Vis absorption spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) analysis, inductively coupled plasma (ICP) spectroscopy, and photoluminescence (PL) spectroscopy. The amount of g-C 3 N 4 was systematically [a]

One-step synthesis of graphitic-C 3 N 4 /ZnS composites for enhanced supercapacitor performance

“…The g-C 3 N 4 carbon materials with excellent mechanical strength and thermal conductivity show good performance in many fields such as wastewater detoxification [17] , H 2 production [18] , fuel cells [19] , and supercapacitors [20] . To the best of our knowledge, g-C 3 N 4 /ZnS composites have been widely investigated in the photocatalytic field [21][22][23] . However, no reports about the supercapacitor performance studies of g-C 3 N 4 /ZnS composites have been recorded.…”

Experimental Investigation with DFT Analysis Towards a Promising Recyclable Photocatalyst from g‐C3N4/ZnS Nanocomposite

“…This stable polymorph of carbon nitrides having two dimensional sheet like electronic structure with moderate bandgap (∼ 2.7 eV), possesses high thermal and chemical stability and is currently being investigated for various applications, such as, in lithium ion battery, catalysts, lubricant, [17,18] sensor, [19,20] and photocatalytic applications. [8,9,[11][12][13][14]21,22] However, the high recombination rate of photogenerated electron-hole pairs in pristine g-C 3 N 4 limits its practical application as efficient photocatalyst. [23,24] Several strategies have, therefore, been developed in order to enhance the photocatalytic performance of g-C 3 N 4 which includes doping with metals/non-metal atoms, [25,26] tailoring the surface morphology of g-C 3 N 4 [27,28] or creating heterojunction by making composite with other nanostructures.…”

Synthesis of a ZnO/CdS/TiO2 Composite with Enhanced Photocatalytic Activity and Stability by a Simple Solution‐Based Method

“…Recently, with rapid industrial development, water pollution caused by aqueous wastes, especially refractory organic pollutants, has become a major problem all around the world. Since Fujishima and Honda reported the photoelectrolysis of water on TiO 2 , more attention has been paid to semiconducting photocatalytic materials for water pollution abatement . As an important semiconductor material, ZnO, due to its high electron mobility, nontoxicity, low cost, and diverse nanostructures,, has been widely used as an effective photocatalyst , .…”
