An Inclusive Review on Recent Advancements of Cadmium Sulfide Nanostructures and its Hybrids for Photocatalytic and Electrocatalytic Applications

In situ synthesis of CdS@NH2-MIL-125 nanocomposite for the enhanced photocatalytic oxidative desulfurization of dibenzothiophene

“…However, CdS has some limitations, such as its low band gap, that cause an easy recombination of generated electron-hole (e − /h + ) pairs, which reduces its photocatalytic activity alone. [30][31][32] Therefore the hybrid heterogeneous structure of a MOF and CdS as photocatalyst could affect the light absorption and photocatalytic activities. 22,32 Considering this matter, we commenced our work for the successful synthesis of the MOF nanocomposite CdS@NH 2 -MIL-125 and used it as photocatalyst under visible-light irradiation (12 W blue LED) for the oxidative desulfurization of dibenzothiophene (DBT) under an oxygen atmosphere and at room temperature (Scheme 2).…”

A Novel Hydrothermal CdS with Enhanced Photocatalytic Activity and Photostability for Visible Light Hydrogenation of Azo Bond: Synthesis and Characterization

“…In addition, it has good carrier transport capacity, which can make photogenerated electrons and holes mobile in a timely and efficient manner, making redox processes reliable on its surface, possibly at the expense of fast recombination [ 13 , 14 ]. For these reasons, CdS is considered one of the most prominent semiconductors in photocatalysis [ 15 , 16 , 17 ]. However, the use of CdS itself presents some fundamental drawbacks, such as poor photostability, accrued from severe photo corrosion and exceedingly fast charge carrier recombination, that limits its efficiency.…”

Synthesis of hierarchical Cd-Ni-MOF micro/nanostructures and derived Cd-Ni-MOF/CdS/NiS hybrid photocatalysts for efficient photocatalytic hydrogen evolution

“…However, the high recombination efficiency of photogenerated carriers and poor stability are challenges that still need to be overcome. [4][5][6][7][8] Efforts have been made to improve the photocatalytic activity of CdS-based semiconductors, such as tuning the morphology, loading the co-catalyst, forming a solid-solution with other semiconductors, and constructing heterostructures.…”
