Catalyst Materials for Oxygen Reduction Reaction

2021
In order to prepare an oxygen reduction electrocatalyst with high catalytic performance, the catalyst is usually loaded on a carrier material with high specific area during the preparation process, this is because the catalyst carrier material can perform the functions of supporting and dispersing of active components, mass transfer, electricity, and ...

Engineering Molecular Heterostructured Catalyst for Oxygen Reduction Reaction

Journal of the American Chemical Society, 2023
Introducing a second metal species into atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts to construct diatomic sites (DASs) is an effective strategy to elevate their activities and stabilities. However, the common pyrolysis-based method usually leads to substantial uncertainty for the formation of DASs, and the precise identification of the

Electro-Catalysis of Oxygen Reduction Reaction

ECS Transactions, 2010
This paper is a short review of the recent developments in understanding trends in electro-catalysis of the oxygen reduction reaction (ORR). Our focus is on atomic scale simulations at the density functional theory level. First, we investigate the models and the approximations that have been assumed, and thence we reach the conclusion that trends in ...

Magnetic Field Enhanced Oxygen Reduction Reaction via Oxygen Diffusion Speedup

Small Methods
AbstractThe mass‐transfer of oxygen in liquid phases (including in the bulk electrolyte and near the electrode surface) is a critical step to deliver oxygen to catalyst sites (especially immersed catalyst sites) and use the full capacity of oxygen reduction reaction (ORR).

Oxygen Reduction Reactions of Monometallic Rhodium Hydride Complexes

Inorganic Chemistry, 2012
Selective reduction of oxygen is mediated by a series of monometallic rhodium(III) hydride complexes. Oxidative addition of HCl to trans-Rh(I)Cl(L)(PEt(3))(2) (1a, L = CO; 1b, L = 2,6-dimethylphenylisocyanide (CNXy); 1c, L = 1-adamantylisocyanide (CNAd)) produces the corresponding Rh(III) hydride complex cis-trans-Rh(III)Cl(2)H(L)(PEt(3))(2) (2a-c ...

Tuning Nanoparticle Catalysis for the Oxygen Reduction Reaction

Angewandte Chemie International Edition, 2013
AbstractAdvances in chemical syntheses have led to the formation of various kinds of nanoparticles (NPs) with more rational control of size, shape, composition, structure and catalysis. This review highlights recent efforts in the development of Pt and non‐Pt based NPs into advanced nanocatalysts for efficient oxygen reduction reaction (ORR) under fuel‐

Photoelectrochemical Oxygen Reduction Reaction Using Phthalocyanines

ECS Meeting Abstracts, 2015
The oxygen reduction reaction (ORR) has attracted broad interest not only with respect to biological processes, such as cellular respiration, but also in terms of practical energy conversion, i.e. cathodic reactions in fuel cells. Because the use of light energy is one of the promising alternatives to platinum that is utilized as an efficient catalyst ...

Advanced electrocatalysts for oxygen reduction reaction

2019
Platinum (Pt)-based metals are the most used electrocatalysts, but the high cost and scarcity of Pt hinder its wide application. Alloying Pt with other transition metals or developing non-precious metal catalysts with comparable performance to Pt is promising to address the cost issue.
