Fabrication of codoped photocatalysts is a developing area of research. Herein, we explore the visible light photocatalytic properties of Cu, Zn codoped BiVO 4 particles. Doping lower valent cations (Cu and Zn) makes the BiVO 4 surface more acidic and enables us to target the basic crystal violet (CV) dye. The adopted hydrothermal protocol of synthesis results in the formation of Cu−Zn codoped monoclinic BiVO 4 particles. Undoped monoclinic BiVO 4 , prepared by the same protocol, showed significant formation of oxygen vacancies. XPS analyses confirm the coexistence of Cu 2+ /Cu + and Zn 2+ dopants. Increased dopant percentage reduced oxygen vacancies. XRD indicates that Cu 2+ /Cu + or Zn 2+ dopants generally substitute Bi 3+ in BiVO 4 . All photocatalysis activities for CV degradation are reported under near-neutral pH conditions. A typical codoped BiVO 4 photocatalyst with 1% Zn and 2% Cu demonstrated the best CV degradation photocatalytic activity. The activity of this Zn, Cu codoped photocatalyst is better than that of pure, Zn-doped, and Cu-doped BiVO 4 samples. Active species trapping experiments indicated the possible photocatalysis mechanism. The photocatalysts exhibited appropriate recyclability and photostability.

“…In another study, Cu-doped BiVO 4 was also reported for PEC CO 2 reduction toward HCOOH formation where Cu 2þ ions in BiVO 4 provide abundant active sites for the adsorption and activation of CO 2 . [106] Cu addition to BiVO 4 reduces interfacial charge separation resistance and increases the charge transfer and surface reaction rates, as shown in Figure 8a. Hence, the optimized sample of Cu─BiVO 4 showed high selective electroreduction of CO 2 toward formate formation with a FE of 87.15% at À1.0 V versus RHE (Figure 8b,c).…”

Solar‐driven photoelectrochemical (PEC) CO2 conversion to valuable chemicals, combining the advantages of photocatalysis and electrocatalysis, represents a promising approach towards establishing a carbon‐neutral society and harnessing solar energy. Photoelectrode materials doped with metals and/or non‐metals have shown promise in achieving high CO2 reduction efficiency. Metal or non‐metal doping entails introducing a heteroelement into the semiconductor, thereby modifying the band potentials of the semiconductor through the addition of a defective state. This alteration may improve the charge transfer kinetics of the catalysis. Furthermore, doping aids in creating active CO2 adsorption offers anchoring sites for CO2 molecules, and can promote product selectivity. This review aims to provide a concise summary of elemental‐doped photoelectrodes for converting CO2 into fuels through photoelectrochemical processes. We discuss several key factors affecting the performance of PEC CO2 reduction, including the interaction of reactants with catalysts, reaction conditions, and the impact of the photoelectrode. Moreover, we discussed various PEC CO2 reduction systems, with a specific focus on enhancing the efficiency of CO2 reduction. Finally, we provide a summary of key considering aspects for further development of the PEC CO2 reduction.This article is protected by copyright. All rights reserved.

“…The authors attributed the performance of catalyst to the presence of oxygen which improved the conductivity due to higher electronegativity. In another research work, Gao and co-workers 164 investigated Cu-doped BiVO 4 electrocatalyst for PEC CO 2 reduction to formate. The catalytic performance of Cu-doped BiVO 4 reached the highest formate selectivity and FE (87%) with 8% Cu loading at −1 V (RHE) reaction conditions.…”

Excessive greenhouse gas (GHG) emissions arising from nonrenewable fossil fuel utilization are causing serious climate change. Since carbon dioxide (CO 2 ) contributes about 76% of GHGs in the atmosphere, utilization of CO 2 could reduce its negative impact on the environment. Among the technologies available for CO 2 conversion, photocatalytic (PC) and photoelectrocatalytic (PEC) reduction of CO 2 into valuable solar fuels have made significant progress. These two technologies are environmentally friendly and effective in concurrently solving energy crises. Insights on the principles, thermodynamics, and limitations of photocatalysis/photoelectrocatalysis using sustainable energy for reducing CO 2 are elucidated in this review. The configurations of cathode−anode and the proton exchange membrane in PEC membrane reactors are discussed. The advances of photoelectrocatalysts such as titania, copper oxides, complex metal−organic frameworks (MOFs), membrane-based immobilized, and metallic photoelectrocatalysts for PEC reduction of CO 2 are also incorporated. Discussion of possible reaction mechanisms using DFT simulation to postulate feasible pathways occurring on catalyst surfaces is presented. It is recognized that PEC CO 2 reduction is critical in the utilization of CO 2 and solar energy research. It is also deduced that advances in reactor configurations along with photoelectrocatalyst materials are vital in mitigating excess CO 2 emissions to generate solar fuels.
