Summary: Cadmium sulfide (CdS) is an effective semiconductor catalyst utilized in split water hydrogen evolution, but rapid recombination of photogenerated electron-hole pairs hinders its application. The synthesis of a CdS/MoS2 mixed-dimensional heterojunction improves the photocatalytic performance by promoting separation of electron-hole pairs and leveraging MoS2 as a co-catalyst. Additional enhancement in photocatalytic activity with nearly four times improvement is achieved by applying a voltage, facilitating faster carrier mobility and better photocatalytic performance.

Summary: A series of MoS2-loaded CdS nanorods have been fabricated, with MoS2 spatially distributed on the tips or both tips and walls of the CdS NRs. The presence of a spatial electric field between CdS NRs and MoS2 tips strongly induces photogenerated electron-hole separation and electron transfer. MoS2 located on the tips of CdS NRs can better separate electron-hole pairs and suppress charge recombination, leading to superior photoactivity.

Summary: Polyaniline (PANI) and multi-walled carbon nanotubes (MWCNTs) were incorporated into hollow CdS spheres to create CdS/PANI/MWCNTs nanocomposites. These nanocomposites were utilized as photo-catalysts for the degradation of sodium butyl xanthate (SBX) in wastewater. The optimized CdS/PANI/MWCNTs catalyst exhibited excellent ultraviolet-light-driven photocatalytic performance with a degradation rate of 99.2% in 70 minutes. The enhanced catalytic activity was attributed to the facilitated separation of photogenerated electrons and holes by PANI, as well as the promotion of SBX adsorption and electron migration by MWCNTs. The stability of CdS/PANI/MWCNTs was also demonstrated by the inhibited photocorrosion of CdS.
