“…The very strong absorption band at 1233 cm −1 and strong band at 1318 cm −1 , 1403 cm −1 correspond to the C–N stretching vibrations (in which the C–NH–C and C–C vibrations are probably involved). The band at 1463 cm −1 corresponds to the number of rings of the heterocyclic structure, and the strong bands at 1563 cm −1 and 1645 cm −1 indicate stretching vibrations of the C=N bonds of g-C 3 N 4 heterocycles 62 , 63 . The wide absorption peaks observed between 3000 – 3700 cm −1 consist of several components.…”

The main goal of this research is to investigate the effectiveness of graphitic carbon nitride (g-C3N4, g-CN) in both bulk and nanosheet forms, which have been surface-modified with silver nanoparticles (Ag NPs), as photocatalysts for the degradation of acid orange 7 (AO7), a model dye. The photodegradation of AO7 dye molecules in water was used to test the potential photocatalytic properties of these powder materials under two different lamps with wavelengths of 368 nm (UV light) and 420 nm (VIS light). To produce Ag NPs (Ag content 0.5, 1.5, and 3 wt%) on the g-CN materials, a new synthesis route based on a wet and low-temperature method was proposed, eliminating the need for reducing agents. The photodegradation activity of the samples increased with increasing silver content, with the best photocatalytic performances achieved for bulk g-CN samples and nanosheet silver-modified samples (with the highest content of 3 wt% Ag) under UV light, i.e., more than 75% and 78%, respectively. The VIS-induced photocatalytic activity of both examined series was higher than that of UV. The highest activities of 92% and 98% were achieved for the 1.5% Ag-modified g-CN bulk and nanosheet materials. This research presents an innovative, affordable, and environmentally friendly chemical approach to synthesizing photocatalysts that can be used for degrading organic pollutants in wastewater treatment.

“…[5][6][7] Organic pollutants and various dyes badly affect human health as well as aquatic ecosystem. [8][9][10] Removal of these pollutants from water bodies is an important topic of research these days. There are several techniques in practice to purify polluted water such as adsorption, electrocatalysis and photocatalysis.…”

“…[29,30] In recent times, FeVO 4 has been a versatile choice for the photocatalytic applications due to the high visible light responsive activity and it is being studied extensively for various organic dye degradations. [10,15,25,31] It is also being observed that it has some limitations like photogenerated electrons and holes gets recombined faster. [31] This recombination and low charge transfer properties limit their application in photocatalytic applications.…”

“…It is evident from these recent studies on FeVO 4 , studying the novel structures of this visible light catalyst for novel drug degradation, organic dye degradation and electrochemical activity is worth for development of novel materials for environmental and energy applications. [10,15,25,32,37] Herein, a novel hydrothermal synthesized FeVO 4 on the rGO layers as a composite is presented as a perfect multifunctional material. Simple hydrothermal reaction was productively used to synthesize FeVO 4 NPs and dispersed on rGO through simple ultrasonic attrition as a composite.…”

Constructing novel multifunctional materials is a promising approach to boost the catalysis activity and electrochemical performance simultaneously. Herein, hydrothermal synthesized FeVO4 nanosized particles dispersed on reduced graphene oxide (rGO) through cost‐effective simple sonochemical assisted route are developed as an efficient material for photocatalysis activity and high‐value‐added supercapacitor applications. The synthesized materials were characterized for structural and morphological purity and found to be in single phase and nanostructured. rGO‐FeVO4 composite shows excellent photodegradation of Levofloxacin (LVO) drug (100% over 80 min) compared with FeVO4 owing to the bandgap in visible region and larger surface area. Further, the optimized rGO‐FeVO4 composite was employed into supercapacitors, and it showed 3 times higher capacitance (211.4 F/g at 0.5 A/g) compared with FeVO4 (70.4 F/g) using half‐cell measurements. Moreover, the developed symmetric supercapacitors (full cell; SSCs) using rGO‐FeVO4 composite device showed 109 F/g capacitance at 0.5 A/g current density having high energy density of 13.6 Wh/kg at the power density of 450 W/kg. The proposed rGO‐FeVO4 composite proved its multifunctional outcomes, which can open new opportunities to develop such materials for numerous future applications.
