| Description: |
The N2S2 molecular systems with nd metal are well known for a long timei. Many potential applications were proposed, including antitumor activityii, however few reports can be found in the literature describing the use of MN2S2 based thiocarbazones as electrocatalysts for protons reduction. Cyclic voltammetry experiments, performed showed electrocatalytic response for H2 evolution in DMF with increasing current response as concentration of trifluoroacetic acid is raised. These promising results and the easiness to tune the systemrsquo;s electrochemical behaviour by varying the ligand/metal could provide access to a new class of molecular catalysts for hydrogen evolution. Continuous flow rig with in-line GC analysis was used to detect the produced H2. It was found that applying a potential of -1.2 V vs Ag/AgCl/KCl electrode at mercury working electrode results in formation of molecular hydrogen. Comparing this value with the charge consumed during the electrolysis, converted to the theoretical amount of hydrogen, the Faradaic yield of the process was calculated. The best resultats in the catalytic hydrogen production were present the compounds of Co and Ni, characterized by Faradaic yield between 80-93 % and TON between 21-43. |
