Summary: Currently, the global energy shortage and environmental pollution are important issues that need to be addressed. Fossil fuels, the traditional energy source, contribute to greenhouse gas emissions and exacerbate global warming. Green energy, particularly hydrogen, is seen as a promising alternative. Photocatalytic water splitting (PWS) under solar irradiation has the potential to address energy and environmental challenges. In this process, carbon-based materials such as graphene, carbon nanotubes, and carbon quantum dots can act as efficient photocatalysts. This review provides a comprehensive explanation of the mechanism and chemistry of carbon-based photocatalytic semiconductors for hydrogen production, as well as discussing the challenges and future prospects of PWS.

Summary: A two-step co-doping strategy using in situ fluorine doping followed by ex situ titanium doping significantly improves the performance of hematite photoanodes in photoelectrochemical water splitting. The optimized co-doped Fe2O3 photoanode achieves a current density of 1.61 mA cm(-2) at 1.23 V-RHE under solar irradiation, which is 2 and 3 times higher than that of singly-doped titanium or fluorine Fe2O3 photoanodes, respectively. The enhanced performance is attributed to the synergy of fluorine and titanium dopants, which increase positive charges and free electrons in the hematite structure.

Summary: Polycrystalline CuWO4 film is a promising photoanode material for PEC water splitting due to its small bandgap and excellent stability. However, its poor charge transfer characteristics limit its PEC performance. To improve the performance, two modification strategies are employed, using SnO2 as an electron transfer layer and cobalt phosphate as a co-catalyst. These modifications enhance the PEC activity by two times and exhibit excellent stability in a neutral electrolyte. Further developments of synthesis method and other modification strategies could potentially improve the performance.

Summary: Small-area photoelectrodes are widely used for research purposes in PEC water splitting cells. However, for practical applications, it is necessary to develop large-scale photoelectrodes with scalable designs and low-cost fabrication methods. This study discusses the concept of developing large photoelectrodes using dimensional engineering and scalable architectures, similar to the development of thin-film photovoltaic cells. A novel protocol using inkjet-printing as a solution processed thin-film deposition method is proposed for the fabrication of large-photoelectrode modules.
