Tuning the reactivity of cobalt-based H2 production electrocatalysts via the incorporation of the peripheral basic functionalities
TL;DR: In this paper, the multi-dimensional regulatory roles of fluxional basic functionalities during the catalytic H2 production by the cobalt-based molecular complexes have been investigated, where the presence of these peripheral functionalities enhances the H2 evolution activity by boosting the proton transduction around the framework.

Tuning the photocatalytic/electrocatalytic properties of MoS2/MoSe2 heterostructures by varying the weight ratios for enhanced wastewater treatment and hydrogen production
Divya Monga,Soumen Basu +1 more
TL;DR: In this paper, 2D/2D heterojunctions of MoS2/MoSe2 with different weight-ratios (1.73, 1.89 eV, and 3.1) have been prepared by a simple one-step microwave assisted technique.

Ibrahim Munkaila Abdullahi,Jahangir Masud,Polydoros-Chrisovalantis Ioannou,Eleftherios Ferentinos,Panayotis Kyritsis,Manashi Nath +5 more
TL;DR: In this article, the authors reported that the CoSe4-containing coordination complex exhibits a high mass activity (14.15 A g−1) and a much higher turnover frequency (TOF) value (0.032 s−1), at an overpotential of 300 mV.

Strategies for Electrochemically Sustainable H2 Production in Acid
TL;DR: An overview of acidified water electrolysis for systematic investigations of reaction types and system configurations/operations to achieve sustainable H2 production (SHP), and several new strategies for SHP are proposed, including fabrication of symmetrical heterogeneous electrolysis system and fluid homogeneous electrolytic system, as well as decoupling/hybrid-governed sustainability.

Conversion constants for redox potentials measured versus different reference electrodes in acetonitrile solutions at 25°C
TL;DR: In this paper, a critical review of conversion constants amongst various reference electrodes reported in the literature reveals that in most cases the comparisons of redox potential values are far from accurate, and therefore, caution should be exercised when one is comparing the redox properties of complexes measured in CH 3 CN solutions versus different reference electrodes.
Journal ArticleDOI
Splitting water with cobalt.
TL;DR: Cobalt has emerged in the past five years as the most versatile non-noble metal for the development of synthetic H( 2)- and O(2)-evolving catalysts, which can be further coupled with photosensitizers to generate photocatalytic systems for light-induced hydrogen evolution from water.
Journal ArticleDOI
Highly active electrocatalysis of the hydrogen evolution reaction by cobalt phosphide nanoparticles.
TL;DR: The activity was essentially unchanged after 400 cyclic voltammetric sweeps, suggesting long-term viability under operating conditions, and CoP is amongst the most active, acid-stable, earth-abundant HER electrocatalysts reported to date.

A Molecular MoS2 Edge Site Mimic for Catalytic Hydrogen Generation
Hemamala I. Karunadasa,Hemamala I. Karunadasa,Elizabeth Montalvo,Yujie Sun,Yujie Sun,Marcin Majda,Jeffrey R. Long,Jeffrey R. Long,Christopher J. Chang,Christopher J. Chang +9 more
TL;DR: A molecule is reported that mimics the structure of the proposed triangular active edge site fragments of molybdenum disulfide (MoS2), a widely used industrial catalyst that has shown promise as a low-cost alternative to platinum for electrocatalytic hydrogen production.
Journal ArticleDOI
Hydrogen evolution catalyzed by cobaloximes.
TL;DR: Investigations of cobaloxime-catalyzed H(2) evolution, coupled with the thermodynamic preference for a homolytic route, suggest that the rate-limiting step is associated with formation of the hydride.
