Solar energy utilization technologies have been widely explored to solve the global energy crisis because the inexhaustible solar energy can be converted into chemical fuel and electricity. Various semiconductors that are crucial for solar energy utilization have been extensively developed. Among them, cadmium sulfide (CdS) has attracted extensive attention due to its suitable band-gap and excellent electrical/optical properties. However, CdS is still limited by rapid charge recombination, instability and low quantum efficiency. Core-shell structures can provide great opportunities for constructing advanced structures with superior properties to overcome the remaining challenges. This review focuses on the significant advances in core-shell structured CdS nanocomposites for solar energy utilization. Initially, the synthetic methods to construct core-shell structured CdS nanocomposites are reviewed. Then the applications in solar energy utilization are discussed, including photocatalytic\photoelectrochemical water splitting, photocatalytic CO reduction and solar cells. Finally, the perspectives of core-shell structured CdS nanocomposites for solar energy utilization are proposed.
由于取之不尽的太阳能可以转化为化学燃料和电能,太阳能利用技术已被广泛探索以解决全球能源危机。各种对太阳能利用至关重要的半导体已得到广泛开发。其中,硫化镉(CdS)因其合适的带隙和优异的电学/光学性质而备受关注。然而,CdS仍然受到快速电荷复合、不稳定性和低量子效率的限制。核壳结构可为构建具有优异性能的先进结构提供巨大机遇,以克服剩余的挑战。本综述聚焦于用于太阳能利用的核壳结构CdS纳米复合材料的重大进展。首先,综述了构建核壳结构CdS纳米复合材料的合成方法。然后讨论了其在太阳能利用中的应用,包括光催化\光电化学水分解、光催化CO还原和太阳能电池。最后,提出了核壳结构CdS纳米复合材料在太阳能利用方面的前景。
