title: One-step synthesis of hybrid nanocrystals with rational tuning of the morphology.
abstract: Metal-sulfide hybrid nanocrystals (HNCs) have been of great interest for their distinguished interfacial effect, which gives rise to unique catalytic properties. However, most of the reported metal-sulfide HNCs were synthesized via two-step approaches and few were fabricated based on the one-step strategies. Herein, we report a facile one-pot synthesis of CuPt-Cu2S, Pt-Cu2S HNCs, and CuPt nanocubes by simply changing the Pt precursor types. 1-Hexadecanethiol (HDT) was employed in this system to mediate the reduction of metal precursors and also as capping agent and sulfur source. Moreover, CuPd-Cu2S and Au-Cu2S HNCs were successfully prepared by using this one-step method. The catalytic properties of the obtained three nanocrystals were investigated in hydrogenation of cinnamaldehyde. Results show that CuPt-Cu2S HNCs exhibited the highest conversion rate and the highest selectivity toward hydrocinnamaldehyde while 3-phenyl-1-propanol was the only product over Pt-Cu2S HNCs.
