Hydrogen (H2) production has received great attention because of its environmental‐friendly nature. Particularly, photocatalytic H2 production has been proven most efficient technology. Graphite‐like carbon nitride has excellent photocatalytic properties and has been widely used for H2 production. Herein, we report the fabrication of sulfur‐doped graphitic carbon nitride (S‐g‐C3N4) and its application in photocatalytic H2 production. The as‐synthesized S‐g‐C3N4 was authenticated by various advanced physical‐chemical techniques such as SEM, PXRD, and XPS. The optical properties of the as‐synthesized S‐g‐C3N4 was checked by UV‐vis absorption spectroscopy. Further, as‐synthesized S‐g‐C3N4 was explored as photocatalyst for H2 production. Effect of photocatalyst doses and type of solvents have been studied. The obtained results show that improved H2 production of 6002.54 μmol/g can be achieved via S‐g‐C3N4 photocatalyst. The as‐synthesized S‐g‐C3N4 also exhibit good stability, H2 evolution rate of 1200.5 μmol/g.h, and reasonable reusability.

“…With the continuous development of human society and the increasing demand for energy, global consumption of fossil fuels for the generation of electricity is now rapidly increasing to an exaggerated level of about 1000 barrels of oil being burned every second, and 80 percent of the current energy comes from traditional non-renewable energy sources, such as coal, oil and natural gas. 1–3 However, the non-renewable nature of traditional fossil fuels and the high level of pollution caused by the greenhouse gases emitted by their combustion have forced people to explore feasible strategies for obtaining cleaner energy, and developing environmentally friendly renewable energy sources is crucial to a sustainable development approach. 4–7 In recent decades, solar-driven photocatalytic hydrogen evolution reaction (HER) with water splitting technology for the production of hydrogen fuel has been widely explored as an ideal way to obtain hydrogen energy to replace traditional fossil energy sources, which is primarily due to the fact that solar energy and water are theoretically inexhaustible, and the burning product of hydrogen energy is water, which does not have any environmental polluting properties.…”

“…9,10 To improve the PEC performance, ternary semiconductors such as BiVO 4 , Bi 2 WO 6 , NiFe 2 O 4 , and CuFeO 2 have emerged as promising options due to their narrow band gap (approximately 2.0 eV) and impressive solar-to-hydrogen (STH) conversion efficiency exceeding 10%. 8,11 However, the metal tungstates, such as ZnWO 4 , NiWO 4 , CuWO 4 , CoWO 4 , MgWO 4 , and Bi 2 WO 6 , as a subject of investigation in PEC studies have not been extensively studied. The CuWO 4 is an n-type semiconductor with high stability and a band gap of approximately 2.2 eV, making it a desirable choice for use as a photoanode for water oxidation.…”

The enhancement of efficient, visible-light active photoanodes is vital for advancing photoelectrochemical (PEC) water splitting as a sustainable and environmentally friendly energy alternative. In this study, we explore the potential of WO 3 / CuWO 4 /Ag heterojunction thin films fabricated by magnetron sputtering on n-Si substrates as viable photoanodes. The synergetic effects of heterojunction formation and Ag nanoparticle dispersion contribute to superior visible-light absorption, charge transfer, and separation efficiency. The influence of Ag nanoparticle decoration achieved through solid-state dewetting phenomena was studied in terms of structural and microstructural changes and photoelectrochemical responses. Surface topography observations revealed that the WO 3 /CuWO 4 /Ag thin film exhibited the highest surface area ratio of 22.7%, approximately a threefold increase compared to the pure WO 3 thin films. The photoluminescence (PL) and time-resolved photoluminescence (TRPL) results demonstrated that the heterojunction configuration promotes effective charge separation and an increased carrier lifetime of ∼20.1 ns. PEC analysis showed a substantial enhancement in photocurrent density of 1.53 mA cm −2 (1.0 V vs Ag/AgCl), approximately 2.32 times greater than that of WO 3 , and an increased applied bias photon-to-current efficiency (ABPE) of approximately 0.91%, compared to 0.43% for WO 3 and 0.50% for WO 3 /CuWO 4 photoanodes. Moreover, the WO 3 /CuWO 4 /Ag photoanode demonstrated remarkable long-term stability with a current density of 0.21 mA cm −2 for about 4.5 h. These findings underscore the potential of WO 3 /CuWO 4 /Ag heterojunction photocatalysts for PEC water splitting and emphasize the significance of the synergetic effect of Ag decoration and heterojunction structure formation in achieving clean and sustainable hydrogen production. Additionally, this research may inspire further studies on surface plasmon metal nanoparticle dispersion with controlled size and shape, using a simple solid-state dewetting technique for the development of efficient electrodes in next-generation water splitting applications.
