“…Also, the hollow structure of Ag/CeO 2– x S x can improve the light-absorption capability by multiple light scattering effects. Moreover, the work function of CeO 2– x S x and Ag is 4.69 and 4.26 eV, respectively. , When Ag contacted CeO 2– x S x , a built-in electric field with the direction from Ag to CeO 2– x S x was generated. Due to the band bending and electric field that is already present, the photoexcited CB electrons of CeO 2– x S x can be rapidly transported to Ag, effectively suppressing the electron–hole recombination.…”

Photocatalytic degradation of organic contaminants is thought to be a potential means for resolving the growing challenge of environmental pollution. However, the efficacy is severely constrained by ineffective light harvesting and slow charge separation. Herein, ultrafine Ag nanoparticles immobilized in sulfur-doped hollow CeO 2 spheres (denoted Ag/CeO 2−x S x ) were synthesized through self-assembly and a subsequent heat-treatment strategy. Obtained Ag/CeO 2−x S x shows promoted utilization efficiency of light, remarkably improved photogenerated carrier separation efficiency, and enlarged surface area. Coupling the synergetic enhancement of light harvesting and charge separation, optimized Ag/CeO 2−x S x exhibits superb photocatalytic tetracycline degradation activity (94.2%, 60 min) under visible light irradiation, and its corresponding rate constant (0.0397 min −1 ) was nearly 28.4-fold higher than that of commercial CeO 2 (0.0014 min −1 ). This analysis provides a simple method for building high-efficiency photocatalysts for solar light-driven wastewater treatment.

“…The effectiveness of this transfer is contingent upon the alignment of the semiconductor’s band levels with the Fermi level of the metal. Furthermore, electron or hole transfer can transpire at energy levels below the bandgap provided that the energy levels are in sync. , After the excitation and decoherence of LSPR, the DET process takes place, leading to the generation of a pool of thermal electrons that are available for transfer. However, it remains unclear whether excited electrons from PNPs are transferred to semiconductor CB, whether the photogenerated electrons in the CB are captured by PNPs, or whether both of the two processes occur.…”

The massive consumption of fossil energy leads to excessive emissions of CO2, which has caused global warming. Solar-driven CO2 conversion is a promising avenue that could solve the energy crisis and environmental pollution issues simultaneously. For photocatalytic CO2 conversion reactions, several photocatalysts have been developed such as semiconductors and plasmonic metal-based catalysts. Among them, plasmonic metal-based catalysts have attracted extensive attention due to their strong light harvesting capacities and low electron–hole pair recombination rates, which are beneficial for photocatalytic CO2 conversion. This review summarizes the progress of plasmonic metal-based catalysts in CO2 reduction with H2, CH4, H2O, and organic chemicals and generalizes the mechanism of plasmonic metal-based catalysts in CO2 conversion reactions.

“…[108] Further, it was reported that plasmonic-metal/twodimensional SC nanocomposites are used in photocatalysis and hence valuable for the photocatalytic water splitting to produce hydrogen. [109] With a suitable bandgap of 2.37 eV, BiVO 4 is a promising n-type SC photocatalyst for the photoelectrochemical water splitting to produce hydrogen. BiO 4 act as a photoanode, absorbing approximately 10% of solar energy and creating 7.5 mA cm− 2 of maximum photocurrent.…”

The degradation of fossil fuel and worse environmental conditions leads to the emergence of hybrid semiconductor (SC) nanomaterials as photocatalysts. Hybrid SCs have interesting physical, mechanical, optical, chemical, and electronic characteristics. Due to these properties’ absorption of light and transfer of charge takes place frequently and hence act as multifunctional surface. These materials should be attributed to their optical and electrical properties and act as multifunctional surfaces in energy production, fuel generation, environmental remediation, sensing, etc. When SCs combine with noble, non‐noble metal, metal oxide, and some carbon‐based materials, they explore wide applications in various fields. Photocatalysis is an effective and sustainable technology to reduce or fix energy concerns and environmental corrosion problems. By going through the extensive literature review, few topics are focused on designing and working mechanisms of hybrid materials. In this way, the present review article explains the properties, surface‐interface engineering, design, and applications (energy and environmental) of hybrid nanomaterials, emphasizing their photocatalytic nature. Additionally, the appealing directions, scientific challenges, and the reasons behind the poor stability of Hybrid SC photocatalyst nanomaterials for energy and environmental applications are discussed. Finally, the concluding remarks and the current challenges with future prospects in this domain are highlighted.
