“…The core-shell structure of AgVO 3 /Fe 2 O 3 has caused the enhancement of the photocatalyst surface and light absorption ability and facilitates charge separation. In another study, irregularly shaped CuFe 2 O 4 and rod-like AgVO 3 were distributed on rGO nanosheets [104]. This novel composite achieved 9 mmol.g -1 .h -1 hydrogen evolutions with high stability and recyclability (Fig.…”

Photocatalysis is known as a new and cost-effective method to solve the problems of energy shortage and environmental pollution. Although the application of this method seems practical, finding an efficient and stable photocatalyst with a suitable bandgap and visible-light sensitivity remains challenging. In this context, vanadate compounds photocatalysts have been synthesized and used as emerging composites, and their efficiency has been improved through elemental doping and morphology modifications. In this review, the major synthesis methods, and the design of the latest photocatalytic compounds based on vanadate are presented. In addition, the effect of vanadate microstructures on various photocatalytic applications such as hydrogen production, CO2 reduction, and removal of organic pollutants and heavy metals are discussed. For instance, the application of a 2D-1D BiVO4/CdS heterostructure photocatalyst enhances 40 times the hydrogen production from benzyl alcohol than pure BiVO4. Similarly, the InVO4/Bi2WO6 composite has a superior photocatalytic capability for the reduction of CO2 into CO compared to pure InVO4. A CO production rate of 18 μmol.g−1.h−1 can be achieved by using this heterostructure. Regarding the organic pollutants’ removal, the use of Montmorillonite/BiVO4 structure allows a complete removal of Brilliant Red 80 dye after only 2 hours of irradiation. Finally, copper heavy metal is reduced to 90 % in water, by using BiVO4/rGO/g-C3N4 optimized photocatalyst structure. Other examples on decorated vanadate compounds for enhancing photocatalytic activities are also treated.

“…Sergei Poskunov et al designed a novel photocatalyst, for which a single atom of gold, silver, and copper was deposited on the surface of TiO 2 , and analyzed its electronic properties using real-time, time-dependent density functional theory (RT-TD-DFT) [23]. Conclusively, the wider research community has explored new emerging magnetic and nonmagnetic nanomaterials that are based on noble-and non-noble-metal-based photocatalysts for eco-friendly H 2 generation [23][24][25].…”

The energy demand generated by fossil fuels is increasing day by day, and it has drastically increased after the COVID-19 pandemic as industries and household utilities rejuvenate. Renewable sources are thus becoming more essential as easily available, alternative methods of low-cost energy generation. Among these renewables, solar energy, i.e., solar power, is a promising energy source and can be used for solar-based H2 evolution because H2 technology is a leading source of eco-friendly electricity generation, and most of the worldwide efforts to develop this method involve heterogeneous catalysis for H2 evolution via water splitting and its storage, i.e., using a fuel cell. In the current scenario, there is a need to develop a stable, recyclable, and reusable heterogeneous catalyst system, which is a great challenge. In the current study, we have focused on novel ferrite magnetic nanomaterials for recyclable and reusable robust photocatalysis. Moreover, discussions of the factors contributing to the photocatalytic hydrogen evolution, low-cost synthesis techniques, and prospects for making them ideal photocatalysts are uncommon in the literature. The study will impart possible approaches for the design and development of novel ferrite nanomaterials and their nanocomposites for H2 generation in the forthcoming years.
