Synthesis of Zn₃(VO₄)₂/BiVO₄ heterojunction composite for the photocatalytic degradation of methylene blue organic dye and electrochemical detection of H₂O₂

Abstract

In this study, a Zn3(VO4)2/BiVO4 heterojunction nanocomposite photocatalyst was prepared using a hydrothermal route with different molar concentration ratios.

Phytogenic Synthesis and Characterization of NiO-ZnO Nanocomposite for the Photodegradation of Brilliant Green and 4-Nitrophenol

“…e EDX is a significant technique to determine the chemical composition [27]. EDX spectrum is shown in Figure 7, which reveals that the elements within synthesized NiO-ZnO NC are nickel, zinc, oxygen, and carbon.…”

Synthesis and characterization of BiVO4 nanoparticles for environmental applications

“…The intensity of this peak increases with the calcination temperature indicating a fast charge recombination of photo-generated charge carriers (electrons and holes) with suppression the photocatalytic activity. [31][32][33] From the PL spectra, the BiVO 4 NPs calcinated at 400 C is identied to support slower charge recombination, whose rate increases with the increasing calcination temperature towards 600 C. Due to this, the The decomposition percentage of photocatalyst has been calculated using Beer-Lambert's law given below.…”

Construction of 1T-MoS2quantum dots-interspersed (Bi1−xFex)VO4heterostructures for electron transport and photocatalytic properties

“…It is observed that the 1T-MoS 2 @(Bi 0.40 Fe 0.60 )VO 4 composite exhibits the lowest PL emission intensity, indicating a large separation efficiency of photogenerated charge carriers. 34 To further understand the charge transfer in 1T-MoS 2 @(Bi 1− x Fe x )VO 4 photocatalysts, the electrochemical impedance spectroscopy (EIS) technique was used. The measurement was also carried out for a bare glassy carbon electrode (GCE) and 1T-MoS 2 @(Bi 0.40 Fe 0.60 )VO 4 composite.…”

“…Nitrogen cooling system containing an ice bath was used to keep the temperature constant and to avoid thermal degradation or decomposition throughout the experimentation. 34,35,57 The degradation efficiency of the dye (CV%) solutions was obtained by the following formula: 32,34 where C 0 is the initial concentration of dye solution and C is the concentration of dye after every interval of 10 minutes. 34 …”
