“…However, the efficiency of commercial Bi2S3 photoanode is not impressive due to poor charge separation and transportation, which leads to fast charge recombination. Hence, some modifications can be worked on to improve the properties of Bi2S3 such as the decoration of metals, addition of support materials, introduction of defects, and synthesis of heterojunction materials [20].…”

The emission of greenhouse gaseous to the atmosphere as a consequence of the utilization of fossil fuels has significantly contributed to global warming and sudden climax change which aroused a lot of concerns. This occurrence has indirectly spurred interest in hydrogen energy as a future alternative energy due to its environmentally friendly, high efficiency and long-term energy storage. Photoelectrochemical (PEC) water-splitting is a top-notch approach that can efficiently produce hydrogen. Moreover, semiconductor materials like bismuth sulfide have often been used as photoanode material in the PEC water-splitting study due to their narrow bandgap, high optical absorption coefficient, appropriate band alignment and low toxicity. Yet, Bi2S3 photoanode suffers from the rapid recombination of charge carriers which ultimately leads to sluggish water oxidation kinetics and poor charge transfer. Interestingly, the fabrication of fibrous silica bismuth sulfide (FSBS) not only demonstrated a low bandgap energy level but also effectively separated the photoproduced charges. In addition, the FSBS photoanode also showed a photocurrent density of 47.9 mA/cm2 at 1.23 VRHE which is 1.78 times greater than the commercial BS photoanode (26.9 mA/cm2). These findings indirectly exposed the potential of FSBS photoanode towards a sustainable PEC water-splitting application.

Bi‐based semiconducting materials have received tremendous attention due to their availability, non/low toxicity, ecological friendship, rich chemical forms, and good visible‐light‐driven photocatalytic performance. As compared to the commonly investigated trivalent bismuth (Bi(III))‐based photocatalysts, non‐trivalent bismuth‐based materials (NTBBMs), such as BiO2−x, Bi2O4−x, Bi4O7, NaBiO3, and so on, exhibit excellent visible‐light‐ and even full‐spectrum‐driven photocatalytic activity as they hold narrow bandgap, suitable positions of conduction band and valence band, and relatively redox‐sensitive structures. In this review, it is attempted to summarize the recent progress in the preparation, microstructures, and modification strategies of various NTBBMs‐based photocatalysts. At the end, the advantages and disadvantages of NTBBMs‐based photocatalysts and future perspectives are presented.
