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.

Heterogeneous photocatalysts have garnered extensive attention as a sustainable way for environmental remediation and energy storage process. Water splitting, solar energy conversion, and pollutant degradation are examples of nowadays applications where semiconductor-based photocatalysts represent a potentially disruptive technology. The exploitation of solar radiation for photocatalysis could generate a strong impact by decreasing the energy demand and simultaneously mitigating the impact of anthropogenic pollutants. However, most of the actual photocatalysts work only on energy radiation in the Near-UV region (<400 nm), and the studies and development of new photocatalysts with high efficiency in the visible range of the spectrum are required. In this regard, hybrid organic/inorganic photocatalysts have emerged as highly potential materials to drastically improve visible photocatalytic efficiency. In this review, we will analyze the state-of-art and the developments of hybrid photocatalysts for energy storage and energy conversion process as well as their application in pollutant degradation and water treatments.

With the rapid development of industrialization, more and more organic pollutants are entering the water environment, rendering the treatment of organic pollutants a key issue in protecting it. Therefore, finding a convenient and effective method for degrading organic pollutants in water is of great importance. Triboelectrification is known as the process of charge transfer during the friction process. It is always accompanied by the energy level transition of electrons or holes, making it a potential method for catalytic degradation, which we refer to as triboelectrification catalysis. In this study, a set of experimental equipment was developed. The device is composed of a mechanical system, a control system, and a measurement system that can realize the quantitative measurement of the triboelectrification catalysis under different friction pairs, different loads, and different contact frequencies. Using the developed device, we observed stable triboelectrification catalytic degradation. This study performed triboelectrification catalytic experiments on various organic compounds including methyl orange, rhodamine, and tetracycline. The results revealed that these three organic compounds were degraded by 39%, 15%, and 20%, respectively, within three hours of being under the influence of triboelectrification catalysis. Subsequently, this study conducted triboelectrification catalytic experiments using materials with different triboelectric capacities. This study found that the triboelectric capacity significantly impacted the triboelectrification catalytic degradation rate, providing further evidence for the mechanism of triboelectrification catalysis. Additionally, this study found that SiO2 and Al2O3, which also utilize electrons as the primary carrier for triboelectrification, are capable of catalyzing the degradation of a methyl orange solution. Therefore, this study suggests that the triboelectrification catalysis is a versatile and widely applicable method for treating organic pollutants in water. With a broad range of catalyst sources and the ability to effectively degrade various organic pollutants, it shows promise as a solution for the problem of water pollution.
