Summary: Surface modification of electrocatalysts is a key strategy for designing advanced nanocatalysts with improved electrocatalytic performance. This study develops highly dispersed amorphous molybdenum trisulfide-anchored Platinum nanodendrites (Pt-a-MoS3 NDs) as efficient hydrogen evolution electrocatalysts. The enhanced electrocatalytic activity of Pt catalysts is attributed to the highly dispersed a-MoS3, which acts as a preferred adsorption site for the efficient conversion of H+ to H2. Furthermore, the anchoring of highly dispersed clusters to Pt substrate significantly enhances the electrocatalytic stability.

Summary: We demonstrated that the photoresponse of MoS2/QD hybrid phototransistor was greatly enhanced by selecting ligand treatment strategy. The carrier concentration and mobility in MoS2 could be effectively tuned via surface doping of 3-mercaptopropionic acid ligand, resulting in high on-off current ratio and low dark current of around 10 pA. Our work may push a new path to design the interface of mix-dimensional heterostructure and develop high-performance electronic and optoelectronic devices.
