“…To date, a good library of nanostructures has been designed in photocatalysis, including 0D quantum dots, 1D nanowires/nanorods, 2D nanosheets, 3D nanostructures, and so on, which can endow the catalysts with characteristic geometric and electronic structures, showing the different physicochemical properties and activities. In addition, with the understanding of the photocatalytic process, component control strategies (e.g., heterojunction, defects, solid solution, and doping) have been well acknowledged in the broadening absorption of solar light, accelerating conductivity for charge migration and boosting fast kinetics for surface reactions. Hence, both structural and component regulation play a vital role in semiconductor modification to achieve high‐efficiency photocatalytic performance.…”

Mo‐Doped ZnIn₂S₄ Flower‐Like Hollow Microspheres for Improved Visible Light‐Driven Hydrogen Evolution

Designing robust visible light‐driven photocatalysts in terms of the structure and component is an important way for achieving efficient solar hydrogen production. Herein, Mo‐doped ZnIn2S4 (M‐ZIS) flower‐like hollow microspheres assembled by ultrathin nanosheets are reported. The as‐prepared M‐ZIS samples achieve an enhanced H2 generation rate of 4.62 mmol g−1 h−1 under visible light, ten times higher than that of pristine ZIS. The 3D hollow microspheres structure assembled by nanosheets ensures sufficient light harvesting and exposure of more active sites. Meanwhile, the doping of Mo is propitious to regulate the chemical characteristic and electronic structure of ZIS in the merit of ameliorated hydrophilicity, extended light adsorption, accelerated transfer‐separation efficiency of charge carriers, as well as the reduced overpotential of H2 evolution. This model is put forward to obtain an in‐depth understanding of the role that both the 3D hollow hierarchical structure and doping atoms play in photocatalytic water splitting.

“…However, it requires UV light activation due to the wide energy band gap, restraining the efficient utilization of solar energy which is made up of visible light (50%) and near‐infrared light (NIR) (45%). To address this difficulty, it is an urgent need to discover other photocatalysts that will improve the consumption efficiency of solar light and remove the toxic organic pollutants from the environment as solar energy is as an endlessly renewable resource …”

We have synthesized novel BiOCl-CoWO 4 heterostructured nanocomposites through chemical precipitation route with different amount of CoWO 4 using KCl as Cl source at a temperature of 100°C, 4 hours. X-ray diffraction, transmission electron microscopy, UV-visible NIR spectroscopy, photoluminescence spectroscopy, N 2 adsorption-desorption isotherms, and electrochemical impedance spectroscopy were performed to gain the crystal structure, morphology, optical properties, surface area, and charge separation of the prepared photocatalysts. BiOCl-CoWO 4 composites demonstrated the diffraction peaks of both monoclinic CoWO 4 nanoparticles and tetragonal BiOCl indicating the formation of the nanocomposite. TEM observations have shown that CoWO 4 nanoparticles were deposited on the BiOCl surface. Photoluminescence, fluorescence lifetime study, and Electrochemical impedance spectroscopy responses of materials indicated a good separation efficiency of charge carriers in BiOCl-CoWO 4 -1. The photodegradation efficiency of the prepared materials was assessed by the decomposition of rhodamine B (RhB) dye solution under sunlight irradiation. Among the synthesized materials, the BiOCl-CoWO 4 -1 composite photocatalyst exhibited maximum photocatalytic activity. Thus the resulting heterostructure favored the efficient charge and energy transfer between BiOCl and CoWO 4 nanoparticles across the interface. The investigations from the radical scavenger tests showed that photogenerated h + , O 2 •− , and • OH radicals were involved in the photodegradation of RhB.
