Metal‐Thiolate Framework for Electrochemical and Photoelectrochemical Hydrogen Generation

Abstract

Hydrogen has evolved as the cleanest and most sustainable fuel, produced directly from naturally abundant water resources. Generation of hydrogen by electrochemical or photoelectrochemical splitting of water has been conceived as the most effective method for hydrogen production. Herein, a robust solid metal-thiolate framework (MTF-1) was obtained by hydrothermal crystallization of the reaction mixture consisting of 1,3,5-triazine-2,4,6-trithioltrisodium salt and Cu II under mild synthesis conditions. The material was thoroughly characterized and explored as efficient catalyst for electrochemical and photoelectrochemical hydrogen evolution reaction (HER) via water splitting reactions. MTF-1 showed onset potential 0.045 V RHE and overpotential η(@10 mA cm À 2 ) at 0.096 V RHE . The electrochemical surface area of MTF-1 was found to be 509 m 2 g À 1 . The photo current density at pH 5.0 was found to be 0.487 mA cm À 2 at 0.6 V RHE . The feasibility of the reaction pathway was correlated from the density function theory study, which suggested the complete downhill energetics indicating spontaneous electrochemical hydrogen generation in the acidic medium.

“…This isotherm could be classified as a type IV isotherm, corresponding to the presence of mesopores. 60 The Brunauer-Emmett-Teller (BET) surface area of the material was 44.25 m 2 g À1 . The pore size distribution plot shown in Fig.…”

Ag/Pd bimetallic nanoparticle-loaded Zr-MOF: an efficacious visible-light-responsive photocatalyst for H2O2 and H2 production

“…In recent years, bimetallic nanoparticles have captured massive attention in various research fields, including sensing, plasmonics, electrocatalysis, photocatalysis, and specifically heterogeneous catalysis. [19][20][21][22] As a new class of materials, bimetallic NPs are made up of two separate metal components. Typically, they display an amalgam of the qualities of the two component metals, thus making them superior to the individual metal components.…”

Efficient Electrocatalysts for Hydrogen Evolution Reaction Using Heteroatom-Doped MXene Nanosheet

“…However, their high cost and scarcity limit their large-scale applications. Therefore, various materials, including graphene, carbon nanotubes [15], transition-metal dichalcogenides (TMDs) [16][17][18][19][20][21][22], transition metal oxides [23,24], transition-metal carbides (TMCs) [25][26][27][28][29], transition-metal phosphides [29][30][31][32], organic polymers [33,34], and nitrides, have been extensively investigated for replacing expensive Pt-based materials in HER.…”
