Abstract
Finding inexpensive and easily available non-noble metal-based catalysts for electrocatalytic hydrogen evolution reaction (HER) is particularly important for energy conservation, emission reduction and environmental protection. In this paper, three novel tin (IV) 5,15-(bis-pentafluorophenyl)-10-(nitrophenyl) corroles (1, 2, 3) were synthesized, featuring o-, m-, and p-nitro groups at the 10-phenyl position. The electrocatalytic hydrogen evolution reactions (HER) of these complexes in organic and neutral aqueous systems were systematically investigated. Notably, all three complexes demonstrate significant catalytic activity for hydrogen evolution in both systems, and their catalytic performance follows the order 1 > 3 > 2, which indicates that the electron-withdrawing effect of nitro group can significantly affect the catalytic property of tin complex. In the organic phase with TsOH or TFA as proton source, the electrocatalytic HER was found to undergo an “E-ECEC” pathway (E: electron transfer; C: chemical reaction). Furthermore, in the aqueous buffer solution, the TOF value is 92.39 h−1 at an overpotential of 1038 mV.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
