Electrochemical and FTIRS characterisation of NO adlayers on cyanide-modified Pt(111) electrodes: the mechanism of nitric oxide electroreduction on Pt Angel Cuesta and María Escudero, Phys. Chem. Chem. Phys., 2008 DOI: 10.1039/b717396b Electrodeposited noble metal particles in polyelectrolyte multilayer matrix as electrocatalyst for oxygen reduction studied using SECM Yan Shen, Markus Träuble a...
Electrochemical CO2 reduction reaction (CO2RR) is an important process which a potential way to recycle excessive in the atmosphere. Although electrocatalyst key toward efficient CO2RR, progress of discovering effective catalysts lagging with current methods. Because cost and time efficiency modern machine learning (ML) algorithm, increasing number researchers have applied ML accelerate screeni...
The resulting electrocatalyst by low temperature and solvent-free mechanochemical synthesis displays an appropriate bifunctional performance.
State-of-the-art nickel–iron oxyhydroxide catalysts suffer from loss of iron under oxygen evolution reaction (OER) potential. In their Research Article (e202214541), Jaeyoung Lee and co-workers develop a stable OER electrocatalyst by adding tetraphenylporphyrin protective layers. They accelerate the redeposition eluted onto forming nonpolar–polar interface. This not only prolongs population but...
Exploration of heterogeneous molecular catalysts combining the atomic-level tunability of molecular structures and the practical handling advantages of heterogeneous catalysts represents an attractive approach to developing high-performance catalysts for important and challenging chemical reactions such as electrochemical carbon dioxide reduction which holds the promise for converting emissions...
In this article, sulfonic acid-grafted reduced graphene oxide (S-rGO) were synthesized using a one-pot method under mild conditions, and used as Pt catalyst supports to prepare Pt/S-rGO electrocatalysts through a self-assembly route. The structure, morphologies and physicochemical properties of S-rGO were examined in detail by techniques such as atomic force microscope (AFM), transmission elect...
A nanostructured porous gold film (NPGF) was fabricated onto a gold electrode surface by an electrochemical approach involving anodization followed by electrochemical reduction in absence of binary alloys, templates and chemical reducing agents. The electrocatalytic activity of the as-fabricated electrocatalyst was examined towards hydrogen evolution reaction (HER) and very low onset potential ...
Low-cost and high-performance advanced electrocatalysts for direct methanol fuel cells are of key significance for the improvement of environmentally-pleasant energy technologies. Herein, we report the facile synthesis of cobalt phosphate (Co3(PO4)2) nanospheres by a microwave-assisted process and utilized as an electrocatalyst for methanol oxidation. The phase formation, morphological surface ...
The catalytic layers of a low temperature fuel cell must present a sufficient electronic conductivity for a high overall performance and, in this sense, the electrocatalyst support plays an important role. However, regarding carbon nanofibers as support, it is necessary to chemically treat their surface to improve both metal deposition and anchorage, which unfortunately affects negatively the e...
