Description:

As the world’s population grows and improves its standard of life, the demand for energy rises steadily to previously unheard-of heights, and to address this need, solar energy emerges as the leading clean, plentiful, and secure energy source. One of the most promising solutions to reduce the burden on the environment and the supply of energy is solar energy since it is cheap, plentiful, and renewable. As a result, it is very desirable to capture solar energy and transform it into usable energy via photocatalytic processes. Hydrogen has been highlighted as a viable energy carrier in various low greenhouse gas energy scenarios due to its high energy capacity and environmental friendliness. Layered inorganic semiconductors, such as layered titanates (LT), have been used as scaffolds for designing highly efficient photocatalysts for hydrogen generation. Intrinsic ionic conductivity increaseswhen the layers of titanate is exfoliated during the dilute acid treatment, and K+ ions are exchanged with protons in the interlayers, and this explains that exf-HTO also shows better results for hydrogen generation than pristine layered titanate. Here, we demonstrate that the
single-atom-loaded layered titanates indicate better photocatalytic activity in terms of hydrogen production from water.
