Engineering strontium titanate-based photocatalysts for green hydrogen generation: Recent advances and achievements

The production of fuels from renewable energy sources such as sunlight offers a promising approach to store chemical energy. Apart from fundamental improvements, innovative ideas on the design of photocatalytic systems can also advance solar energy utilization by integrating complementary technologies to utilize the solar spectrum more efficiently. This review highlights the recent developments of the new SrTiO3 based photocatalytic systems and other approaches for enhanced separation of photogenerated charge carriers towards surface catalyzed reactions. Based on our survey, SrTiO3 based photocatalysts are one type of widely explored materials for solar water splitting in recent years both from the fundamental approach and for commercial applications. Thus, we intend to summarize the details of SrTiO3 based photocatalysts from starting to advanced research and interesting information of small-scale research to the larger-scale application along with historical progression.
