12 March, 2015 - 01:54

Chem. Commun., 2015, 51,5052-5055
DOI: 10.1039/C4CC10311D, CommunicationThangavel Naresh Kumar, Naveen Chandrasekaran, Kanala Lakshminarasimha Phani
In situ generated S-doped carbon is sandwiched between MoS2 nano-sheets during pyrolysis of Mo(VI)-PDA complex in the presence of elemental sulfur, enriching MoS2 with edge planes and enhancing charge density and electronic conductivity. Phase transformed MoS2[@S-CPDA] electrocatalyzes HER with [small eta] = 160 mV@10 mA cm-2.
