Visible light assisted photocatalytic degradation of crystal violet dye and electrochemical detection of ascorbic acid using a BiVO₄/FeVO₄ heterojunction composite

Abstract

A highly pure BiVO4/FeVO4 heterojunction nanocomposite photocatalyst was synthesized by a facile hydrothermal method. The simple and economical manufacturing process allows easier industrial scale-up and the results contribute to the design of more effective photocatalysts.

An External Energy Independent WO3/MoCl5 Nano-Sized Catalyst for the Superior Degradation of Crystal Violet and Rhodamine B Dye

“…The reaction rate constant was 1.74/s (104.4/min) in the case of the 30 ppm crystal violet, which is the highest to the author's knowledge. RB degrading studies done by Yao W. et al, Wilke [38][39][40]. Other degradation coefficients of this study are summarized in Table 2.…”

“…This light is almost negligible. The reaction was conducted to degrade 30 ppm and 50 ppm of the dyes, which is a high concentration compared to other studies about CV and RB degradation [35][36][37][38][39][40][41]. Trials with 10 ppm Figure 5 shows the catalytic results of CV and RB using synthesized catalysts under normal light conditions.…”

“…The reaction was conducted to degrade 30 ppm and 50 ppm of the dyes, which is a high concentration compared to other studies about CV and RB degradation [35][36][37][38][39][40][41]. Trials with 10 ppm The reaction was conducted to degrade 30 ppm and 50 ppm of the dyes, which is a high concentration compared to other studies about CV and RB degradation [35][36][37][38][39][40][41]. Trials with 10 ppm and 20 ppm were unable to be analyzed since all of the degradations were done within a minute, and observing the concentration for each shorter time interval was too risky from the perspective of accuracy.…”

Electrochemical Determination of Ascorbic Acid Based on AgNPs/PVP‐Modified Glassy Carbon Electrode

“…The GCE has some advantages, such as good stability and conductivity, high rigidity and intensity, and it can be easily modified . In the previous studies, GCE was modified with different materials, such as Mn(III) tetratolylporphyrin chloride (MnTTPCl), Au nanoparticles (AuNPs), multi‐walled carbon nanotubes (MWNTs) and polyethyleneimine (PEI) (AuNPs/MWNTs/PEI), chrysanthemum‐like titanium nitride (CL‐TiN), BaWO 4 nanomaterials, gold nanoparticle‐decorated MoS 2 nanosheets (AuNPs@MoS 2 ), 3,4,9,10‐perylenetetracarboxylic acid (PTCA) and overoxidized dopamine polymer (PDAox), graphene oxide (GO)‐AuNPs, PdPt bimetallic alloy nanowires (PdPt BANWs), Ni(OH) 2 , network‐like carbon nanosheets (NCN), BiVO 4 /FeVO 4 nanocomposite, MoS 2 ‐PANI/rGO, reduced graphene oxide/Prussian blue (PrGO/PB) nanocomposite, and hexagonal boron nitride (h‐BN), for the determination of AA.…”

A Bi2WO6/Ag2S/ZnS Z-scheme heterojunction photocatalyst with enhanced visible-light photoactivity towards the degradation of multiple dye pollutants

“…16 Accordingly, different methods, including sol-gel synthesis, ball milling, hydrothermal synthesis, and coprecipitation, have been used to fabricate heterojunction photocatalysts. 17,18 Although a great deal of effort has been made to exploit more efficient heterojunction photocatalysts over the past few decades, the rapid recombination of photo-induced electron-hole pairs and sluggish charge transport is still an unsolved challenge. 19 In this regard, the present work focuses on the construction of an efficient visible-light-driven heterojunction photocatalyst to overcome the obstacles of rapid charge carrier recombination.…”
