Utilization of solar energy to induce photocatalytic reaction is receiving large attention from the scientific community because of its enhanced potential to address energy and environmental issues. Catalysts that absorb light energy to perform a particular reaction show various applications with great importance in the present world. Water splitting and hydrogen production are appealing technologies for clean, green, and renewable fuel sources. Therefore, it is necessary to summarize the technological progress in the field of photocatalysis along with its future challenges. The special physiochemical, morphological, and structural properties of titanium dioxide-based nanostructured materials encourage researchers to explore its environmental remediation and energy applications. In this Review, we are revealing the current and past research works executed on TiO2-based nanostructures for enhanced photocatalytic applications. Nanosized TiO2 with modifiers exhibit notable photocatalytic reaction toward hydrogen production, CO2 reduction, nitrogen fixation, pollutant removal, etc. A comprehensive encapsulation of various synthesis methods and applications of titanium-based photocatalysts is explained. Additionally, we highlighted the ongoing challenges and opportunities in this area, which will stimulate further testing and exploration to this discipline and successively lead to new discoveries for environmental remediation and energy applications.

Hydrogen gas as a clean energy source, it is a promising alternative to fossil fuels. Therefore, people are actively seeking effective ways to produce hydrogen to cope with the imminent global energy shortage. However, the current production of hydrogen relies on the catalytic reforming of fossil fuels, inducing inevitable environmental pollution. Alternatively, photocatalysis for produce hydrogen gas from reforming alcohols is a promising approach. Especially, other value‐added hydrocarbon products, such as acetone, acetaldehyde, acetic acid, etc., can also be produced during the photoreforming process of alcohols. Meanwhile, reducing the production of COx, making it an environmentally friendly conversion process. Outstandingly, TiO2 and its derivative are excellent photocatalysts. Among them, TiO2 cocatalyzed with noble metal can easily increase the H2 evolution rate to the mmol g−1 h−1 scale. Among the light alcohols isopropyl alcohol has fewer side reactions, methanol and ethanol have higher reaction rate, but they require to reduce the by‐product COx. In this review, the recent developments in this field are summarized; various studies regarding H2 evolution rate, illumination condition, quantum efficiency, etc., are compared; and the development prospects of this field, with the hope of sparking widespread research interest, are proposed.
