Over past three decades, scientists have worked toward creatingdifferent photocatalytic materials with distinct features, with the goal of successful technology transfer.BiTiO (BTO)-based materials offer manyuses in photocatalytic technology, including wastewater remediation and green energy production. To counter the potential limitations of BTO photocatalyst i.e. quick recombination of photogenerated charges and for increasing visible light absorption and enhancing the photocatalytic activity, several approaches including developing surface defects, elemental doping, formation of heterojunctions and construction of oxygen vacancies were examined in this review. This review discusses the different techniques used in the synthesis of BTO based photocatalysts. This study presents the most recent advances in the development of BiTiO-based photocatalysts for the efficient degradation organic pollutants, hydrogen energy production and reduction of carbon dioxide into valuable fuels. At the end, the current issues and future prospective in engineering and use of BTO based photocatalyst for improving photocatalytic activity under lab control and large-scale conditions are also discussed. Conclusively, this review aims to inspire more creative work on designing BTO based photocatalysts with great potential which accelerates the discovery of high performance photocatalysts for environmental remediations.
