摘要：Ga-III chloride tetrakis(pentafluorophenyl) porphyrin (1) was synthesized and shown to be a highly active and stable post-transition metal-based electrocatalyst for the hydrogen evolution reaction (HER). Electrochemical and spectroscopic studies indicate that both the first and second reduction events of 1 are ligand-centered. The 2e-reduced form 1(2-) reacts with a proton to give Ga-III-H species (1-H), which undergoes protonolysis with Bronsted acids to produce H-2. The identification of key i ...More
Ga-III chloride tetrakis(pentafluorophenyl) porphyrin (1) was synthesized and shown to be a highly active and stable post-transition metal-based electrocatalyst for the hydrogen evolution reaction (HER). Electrochemical and spectroscopic studies indicate that both the first and second reduction events of 1 are ligand-centered. The 2e-reduced form 1(2-) reacts with a proton to give Ga-III-H species (1-H), which undergoes protonolysis with Bronsted acids to produce H-2. The identification of key intermediates 1(-), 1(2-), and 1-H leads to a catalytic cycle, which is valuable for the fundamental understanding of the HER. This study presents a rare but highly active HER electrocatalyst with unusual features, including ligand-centered electron transfer and formation of post-transition metal hydride. ...Hide
