2D Bismuthene as a Functional Interlayer between BiVO4 and NiFeOOH for Enhanced Oxygen-Evolution Photoanodes
(Wiley, 2022-10-26)
BiVO4 has attracted wide attention for oxygen-evolution photoanodes in water-splitting photoelectrochemical devices. However, its performance is hampered by electron-hole recombination at surface states. Herein, partially ...
Ultrafast loss of lattice coherence in the light-induced structural phase transition of V2 O3
(American Physical Society, 2022-12-12)
In solids, the response of the lattice to photoexcitation is often described by the inertial evolution on an impulsively modified potential energy surface which leads to coherent motion. However, it remains unknown if ...
Catalytic conversion of alkynes to α-vinyl sulfides mediated by carbene-linker-carbene (CXC) rhodium and iridium complexes
(The Royal Society of Chemistry, 2021-01-21)
The catalytic activity of a set of mono- and bimetallic Rh(I) and Ir(I) complexes bearing carbene-linker-carbene (CXC) bis-triazolylidene ligands (with X = O, N) coordinated in a bridging or chelating fashion was evaluated ...
Separating bulk and surface processes in NiOx electrocatalysts for water oxidation
(Royal Society of Chemistry, 2020-08-10)
Nickel oxide-based catalysts currently represent the state of the art in electrochemical water oxidation in alkaline pH. However, much of their functionality remains poorly understood, particularly regarding catalytically ...
Categorical Variable Mapping Considerations in Classification Problems: Protein Application
(MDPI, 2023)
The mapping of categorical variables into numerical values is common in machine learning
classification problems. This type of mapping is frequently performed in a relatively arbitrary manner.
We present a series of four ...
Catalysis Meets Spintronics; Spin Potentials Associated with Open-Shell Orbital Configurations Enhance the Activity of Pt3Co Nanostructures for Oxygen Reduction: A Density Functional Theory Study
(American Chemical Society, 2020)
One of the main obstacles in the implementation of hydrogen fuel cells (HFC) lies in the efficiency loss due to the overpotential of the oxygen reduction reaction (ORR). Nowadays, the best catalysts for cathodes in HFC are ...
