Engineering a cobalt clathrochelate/glassy carbon interface for the hydrogen evolution reaction

An earth-abundant bimetallic catalyst coated metallic nanowire grown electrode with platinum-like pH-universal hydrogen evolution activity at high current density

“…5 The need of the hour is to develop an earth-abundant pHuniversal HER catalyst that can trigger proton reduction with Pt-like fast kinetics and the least possible overpotential. A rejuvenated self-supported electrode is even more attractive as it allows skipping polymeric binders that block catalytically active sites, 28 and avoiding additional current collectors such as the glassy carbon electrode (GCE), 29 carbon ber paper (CFP), 30 carbon cloth, 31 and Ni or Cu foam. [32][33][34] Rational design of selfsupported electrodes is critically dependent on a fairly large exposed surface, enhanced mass diffusion and efficient electron transport with futuristic applications towards wearable and exible energy devices.…”

Electrocatalytic properties of {Mo3S4}-based complexes with regard to the hydrogen evolution reaction and application to PEM water electrolysis

“…In this paper, we report on the HER properties of two non-PGM thiomolybdate catalysts that could be used in acidic media at the cathode of PEM water electrolysis cells in place of platinum (2H + + 2e À -H 2 ). [12][13][14][15][16][17][18][19][20][21][22] The HER is of course only half of the problem since a similar cost problem is found on the anode side for the OER. However, it is a much more challenging task to find non-PGM alternatives to IrO 2 and the discussion reported here is restricted to the HER on the cathode side of the cell.…”

A Simple and Scalable Approach To Remarkably Boost the Overall Water Splitting Activity of Stainless Steel Electrocatalysts

“…19,20 The utilization of not only noble metal oxides such as IrO 2 and RuO 2 21,22 but also other transition metal compounds as promising OER catalysts 23,24 has shown undoubtedly enhanced performance in the assembly of the overall water splitting devices. 25,26 These electrocatalysts are mostly prepared on 2D planar 27 and 3D substrate structures 28−30 especially glassy carbon 31 and nickel foam/carbon cloth, 32−34 respectively, thereby forming substrate-assisted catalysts. 35,36 However, despite the successful fabrication of these catalysts on 2D and 3D structures, the tendency of the active materials peeling off from the substrates remains an unquestionable challenge, 33,37−39 which should be urgently addressed.…”
