Application of BiVO4 Nanocomposite for Photodegradation of Methyl Orange

Abstract

In this work, BiVO4–graphene photocatalyst was prepared by a facile one-step hydrothermal method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The photocatalytic activity of this compound was investigated by destruction of methyl orange (MO) under visible light irradiation. The photodegradation results show that the prepared BVG compound has higher photocatalytic activity than the pure BiVO4 compound. This compound can degrade 98% of MO under visible light irradiation. This work indicates that BiVO4 compounds are excellent compounds for pollutant degradation under visible light irradiation.

Optical, morphological and photocatalytic properties of biobased tractable films of chitosan/donor-acceptor polymer blends

“…In spite of this, interesting advantages can be envisioned for these biobased films e.g., this type of catalyst is entirely constituted of compounds of an organic nature; hence, they can be considered to be "all-polymer" catalysts. Additionally, biobased films acting as catalysts would help replace the use of inorganic, expensive and potentially toxic catalysts based on Rh, Au, Pt, Ir and Ru that commonly display similar or even lower reduction rates after a few cycles of use (Aghakhaninejad, Rahimi, & Zargari, 2018;Chaker, Chérif-Aouali, Khaoulani, Bengueddach, & Fourmentin, 2016;Dhanalakshmi, Saravanakumar, Prabavathi, & Muthuraj, 2020;Masoud, Nourbakhsh, & Hassanzadeh-Tabrizi, 2017;Vaiano & Iervolino, 2019;Zhang et al, 2019). It is well-known that the duration, versatility, and performance of a catalyst are crucial aspects, especially for light-driven chemical reactions of technological importance.…”

Mechanistic investigation of photocatalytic degradation of organic dyes by a novel zinc coordination polymer

“…2 As a result, photocatalytic degradation of dye wastewater by oxidation has recently become an area of intensive research, 3 where metal-organic frameworks (MOFs) have attracted extensive attention as a new category of semiconductor material for photocatalytic degradation of organic dyes. [4][5][6][7][8][9][10][11][12] Mechanistic studies 13,14 of photocatalytic decomposition of organic dyes [15][16][17] reveal that catalysis consists of three major steps:…”
