First application of Sn (IV) corrole as electrocatalyst in hydrogen evolution reaction

First application of antimony(iii) corrole for electrocatalytic hydrogen evolution

“…The peripheral electron-withdrawing groups lead to a decrease in electron density of the corrole macrocycle, thus causing a positive shift in the reduction peak potential. 7,8,10 Such a scenario may contribute to the potential enhancement of the electrocatalytic performance of the hydrogen evolution reaction.…”

“…Extensive exploration of metal corrole 5 as electrocatalysts has taken place, which is driven by their commendable HER properties, facile structural modulation, and explicit delineation of active sites. Previous studies have highlighted the effectiveness of modulating the hydrogen evolution reaction properties by varying central metals, 6–8 the number of electron-withdrawing groups 9,10 and the position of electron-donating groups. 11,12…”

First Application of Non‐Metallic A2B Type Silicon Corrole Complexes in Electrocatalytic Hydrogen Evolution

“…[11] In addition, the introduction of strong electronwithdrawing substituents and proton-transferring groups such as pentafluorophenyl and crown ether unit into the mesoposition of corroles can further improve the HER performance of metal corroles, and the immobilization of Co corroles onto carbon nanotubes (CNTs) via covalent amide bonds could improve the efficiency and stability of the electrocatalyst. [12] In recent years, Gross et al and Cao et al, as well as our group have extensively studied the application of metal corroles in HER, however, most related studies have focused on transition metal corroles [M = Co, [13] Cu, [14] Ni, [15] Mn, [16] Fe, [17] Rh, [18] Mo [19] ] and some main group metal corroles [M = Ga, [20] Sn [21] ]. The study of non-metallic centered corroles is particularly scarce, with only phosphorus corrole being reported quite recently.…”
