Description
Summary:Finding a renewable, cleaner and inexpensive source of energy has been a momentous challenge to the researchers. Among others, one intriguing solution is molecular H2 which is considered as an ideal energy source for the future needs. Obtaining H2 is extremely appealing but difficult to achieve. One of the most viable solutions is the electrocatalytic hydrogen evolution reaction (HER). In this paper, we presented electrocatalytic HER performances of pyridoxal-semi carbazone (PLSC) and pyridoxal S-methyl-iso-thiosemicarbazone (PLITSC) stabilized Co(II) and Co(III) complexes, i.e. ([Co(PLSC)(SO4)(H2O)2], 1) and [Co(PLITSC-H)(PLITSC-2H)].CH3OH, 2)). Both complexes catalyzed the HER in acidic media while complex 2 was found to be more active than complex 1.
