Bismuth (Bi), as a nontoxic and inexpensive diamagnetic heavy metal, has recently been utilized for the preparation of a variety of nanomaterials, such as nanoparticles, nanowires, nanotubes, nanosheets, etc., with a tunable bandgap, unique structure, excellent physicochemical properties, and compositional features for versatile properties, such as near‐infrared absorbance, high X‐ray attenuation coefficient, excellent photothermal conversion efficiency, and a long circulation half‐life. These features have endowed mono‐elemental Bi nanomaterials with desirable performances for electronics/optoelectronics, energy storage and conversion, catalysis, nonlinear photonics, sensors, biomedical applications, etc. This review summarizes the controlled synthesis of mono‐elemental Bi nanomaterials with different shapes and sizes, highlights the state‐of‐the‐art progress of the desired applications of mono‐elemental Bi nanomaterials, and presents some personal insights on the challenges and future opportunities in this research area. It is hoped that the controllable manipulation techniques of Bi nanomaterials, along with their unique properties, can shed light on the next‐generation devices based on Bi nanostructures and Bi‐related nanomaterials.

“…[131][132][133][134][135][136][137][138] The design of a large number of nanomaterials with heterojunctions at the interface between two different crystalline regions indeed has great effects on the development of advanced materials for versatile applications. [139][140][141][142][143][144][145] For example, Zhou et al [134] in 2015 demonstrated the successful synthesis of ultrathin trigonal Te/Se alloyed nanowires with a tunable composition and bandgap. As is shown in Figure 8a, the wire morphology and uniform size distribution with a mean diameter of ≈10 nm were obtained.…”

Photoelectrochemical (PEC) water splitting is a promising approach to convert inexhaustible solar energy to hydrogen energy. In this system, the semiconductor is a crucial part as photoelectrode to harvest the solar light and achieve water splitting on the surface. For the surface modification of semiconductor, cocatalyst loading is an effective method to improve the sluggish reaction kinetics. Due to the specific structure of their organic ligands, the metal‐organic frameworks (MOFs) or molecular catalysts as cocatalysts can provide more reaction sites and overcome the interface recombination between semiconductors and cocatalyst layers. The inorganic metal species derived from the MOFs or molecular catalysts also possess porous structures. This review summarizes the recent developments of MOFs and molecular catalysts as well as their derivatives modifying several representative semiconductors for PEC water oxidation reaction. The synthesis methods and performance enhancements are discussed. Finally, this review addresses remarks on current existing changes and perspectives for the further development.
