A review of Solar and Visible Light Active Oxo-Bridged Materials for Energy and Environment

Abstract

Abstract For efficient solar energy conversion toward environmental and energy applications, use of visible-light-active photocatalysis, as a green and sustainable technology, has become a promising technology. A visible-light-active photocatalyst (λ > 400 nm), to efficiently harvest solar energy and address a recent primary concern, has been designed and fabricated. An effective separation of photo-generated electron hole pairs and their rapid transport to the semiconductor surface is required for high-efficiency solar photocatalysis. Therefore, significant efforts have been devoted for designing and developing hetero binuclear oxo-bridged systems owing to their unique physical and electronic properties, which make them promising candidates for photocatalysis. These materials exhibit excellent light-harvesting properties due to metal-to-metal charge-transfer (MMCT) excitation and possess band-gap energies that are more suitable for solar light absorption. Recently, hetero binuclear oxo-bridged systems have facilitated the rapid progress in enhancing photocatalytic efficiency under visible light irradiation; therefore, this mini-review aims to provide a systematic study of hetero nuclear oxo-bridged systems for environmental decontamination and artificial photosynthesis (water splitting and photocatalytic CO2 reduction). In conclusion, this review will provide not only an outlook but also few perspectives on the challenges hindering the further advancements of oxo-bridged material for applications in photocatalysis.
