Low overpotential water oxidation at neutral pH catalyzed by a copper(ii) porphyrin

Abstract

Low-overpotential water oxidation catalyzed by copper(ii) porphyrin to produce O2 in neutral aqueous solution and H2O2 in acidic solution.

Mono‐/Multinuclear Water Oxidation Catalysts

“…Epa 1 decreased with increasing pH value,w hich remained constant at pH 7-12;however, Epa 2 was constant at pH 3-12. [30] They found that this complexc ould catalyzew ater oxidationt op roduce H 2 O 2 under acidic conditions;t his may provide new insights into the catalytic mechanism of water oxidation. At pH 8, the currentd ensity increased as the concentration of this catalyst increased, and the rate constant increased as the concentration of HPO 4 2À increased.…”

“…The highly dispersed active species can be anchored to the support or ligand by using this method.F or example, Ni/b 12 -BM (b 12 -BM: b 12 boron monolayer) can be synthesized through the impregnation method. [30] Zhao et al prepared ab inuclear iridium-based heterogeneous catalystb y using this strategy;t his could provide some vital implications for the synthesis of varioush etero-and homogeneous catalysts. However,C l À can combine with H + from the solution, which weakenst he NiÀCl bond and strengthenst he HÀCl bond.…”

Ultra‐thin Co−Fe Layered Double Hydroxide Hollow Nanocubes for Efficient Electrocatalytic Water Oxidation

“…As the increasing fossil fuel consumption, electrochemical water splitting is a promising solution for the problem . Because of the sluggish kinetics and large overpotential resulting from the complex oxidation pathway, oxygen evolution reaction (OER) is regarded as the main bottleneck for water splitting . Along with the fact, many endeavours have been developed to invented efficient electrocatalysts to reduce over‐potential and speed up the OER kinetics.…”

2D Metal–Organic Framework Derived CuCo Alloy Nanoparticles Encapsulated by Nitrogen‐Doped Carbonaceous Nanoleaves for Efficient Bifunctional Oxygen Electrocatalyst and Zinc–Air Batteries

“…[11,40,[54][55][56][57][58][59][60][61] Amongt heses ystems, Cubased bimetallic alloy electrocatalysts have attracted al ot of attention,a sC uc ompounds exhibit biomimetic chemistry with O 2 . [11,[64][65][66] Therefore, it is still challenging to prepareC u-based NC electrocatalysts with homogeneous distribution of Cu species, which prevents the loss in electrocatalytic capabilities.
