Recent steps-forward in the research and development of titanium dioxide (TiO2) based photocalysts for the production of hydrogen via photocatalytic reduction of water was reviewed and presented in this paper. The most promising sustainable alternative renewable fuel is adjudged by the majority to be Hydrogen. Water splitting for the production of hydrogen is an affable approach to achieving large scale green hydrogen for all, thereby facilitating the actualization of the cogently needed hydrogen economy. Photocatalysis, a kind of artificial photosynthesis, is among the prominent candidate processes that have garnered researchers and developers affection and attention, globally, especially in recent decades. TiO2, mostly modified, has been at the forefront among a number of seminal semiconductor compounds and compositions that show varying significant capabilities for this application. Their performances depend upon factors such as surface morphology, band width, and irradiation type and time. The comparable befitted photocatalytic activity of TiO2 has not just single it out causing it gained special interest with no effects. Important improvements towards making an ultra-efficient material from it are being recorded, indicative of the possibility of getting to the ultimate. The remarkable results reported are mostly characterized by use of additives and no-additive techniques in nanomaterial forms to enhance efficiency and durability and to minimize cost. Despite present progress more work is required to attain the prospective considerable seamless market viability.
