Structure effects of NiS and Ni3S2 nanoparticles were investigated for their electrocatalytic activity in the hydrogen evolution reaction in both acid and alkaline media. Owing to the different atomic configurations and crystalline structures, there is a hydrogen adsorption energy difference, which induces a difference in the activity. From density functional theory calculations and experimenta...
Reactive, thermal degradation of py2Pt[MoCp(CO)3]2, (Me)(cod)PtMoCp(CO)3, orfPt3ðdppmÞ3ðCOÞ1⁄2MoðCpÞ g[BPh4]/Vulcan carbon powder composites affords Pt–Mo/carbon nanocomposites containing metal nanoparticles of approximate compositions, PtMo2, PtMo, or Pt3Mo, widely dispersed on the carbon support. Total metal loadings range from 29–58 wt%. When tested as an anode electrocatalyst in a PEM fuel ...
An array of Pd–W alloys was fabricated, and the electrocatalytic activity of the alloys for the oxygen reduction reaction (ORR) in acidic media was screened by scanning electrochemical microscopy. The Pd0.7W0.3 showed the highest activity for the ORR, close to that for Pd0.8Co0.2 and Pt. A Pd–W electrocatalyst loaded on carbon black was formed by the NaBH4-reduction method, exhibiting high acti...
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...
