Abstract

The reduction of fossil fuel usage and the simultaneous increase in the utilization of renewable fuels contribute to mitigating environmental pollution and reducing the Earth's atmospheric temperature. Today, the escalating global population poses a challenge of increased energy consumption, necessitating the adoption of simple and cost-effective methods for energy generation. Water splitting using solar light and photocatalysts for hydrogen production is one such approach. Recent years have witnessed significant advancements in the field of photocatalytic water splitting, with progress extending from fundamental scientific research to practical and scalable applications.

This review begins by examining the influential factors in the design of a photocatalyst, including sacrificial agents, nanoparticle effects, solar spectrum, and the introduction of photocatalysts operating in the UV region. Subsequently, recent advancements in two-dimensional materials and heterogeneous structures for water splitting applications are summarized from a theoretical perspective. Specifically, various two-dimensional materials and heterogeneous structures employed for water splitting are discussed.

Finally, the focus shifts to recent progress in the development of new materials for light absorption in the visible region, insights, and strategies in the field. The discussion concludes with an emphasis on recent advancements in the development of new materials, absorption of light in the visible region, insights, and strategies for further exploration and development.
