Improved oxygen electrocatalysis is crucial for the ever-growing energy demand. Metal-nitrogen-carbon (M-N-C) materials are promising candidates catalysts. Their activity tunable via varying electronic and geometric properties, such as porosity. Because of difficulty in modeling porosity, M-N-Cs with variable surface curvature remained largely unexplored. In this work, we developed a realistic in-pore dual-atom site M-N-C model applied density functional theory to investigate effect on...
Geometry-adaptation during oxygen electrocatalysis makes catalysts behave as ideal and elevates them to the apex of activity volcano.
The use of precious metal electrocatalysts in clean electrochemical energy conversion and storage applications is widespread, but the sustainability these materials, terms their availability cost, constrained. In this research, iron triad-based bimetallic nitrogen-doped carbon (M-N-C) materials were investigated as potential bifunctional for oxygen reduction reaction (ORR) evolution (OER). synthesis FeCo-N-C, CoNi-N-C, FeNi-N-C catalysts involved a precisely optimized carbonization process...
Efficient and sustainable synthesis of performant metal/nitrogen-doped carbon (M–N–C) catalysts for oxygen reduction evolution reactions (ORR/OER) is vital the global switch to green energy technologies–fuel cells metal–air batteries. This study reports a solid-phase template-assisted mechanosynthesis Fe–N–C, featuring low-cost FeCl3, 2,4,6-tri(2-pyridyl)-1,3,5-triazine (TPTZ), NaCl. A NaCl-templated Fe-TPTZ metal–organic material was formed using facile liquid-assisted grinding/compression....
Scaling relations represent a fundamental limitation in electrocatalysis, particularly for the oxygen reduction reaction (ORR), which underpins energy conversion technologies such as fuel cells and metal-air batteries. Improving activity of ORR catalysts requires overcoming scaling relations, i.e. correlations between adsorption energies intermediates. In this review, we summarise existing literature by providing critical meta-analysis, deriving new theoretical principles, proposing taxonomy...
Titanium dioxide coatings of different thicknesses were deposited on the acid-treated multiwall carbon nanotubes (MWCNTs) using controlled atomic layer deposition (ALD). Pt nanoparticles (NP) TiO2/MWCNT supports two methods, viz. sputter-deposition and photo-deposition. Scanning electron microscopy (SEM) scanning transmission (STEM) measurements revealed successful application ALD for TiO2. Both magnetron sputtering photo-deposition found to be efficient well-controlled techniques NPs...
Preparation of electrocatalysts often relies on the use multiple starting materials, with examples arising from a single precursor being less common. We have surveyed series heterobivalent scaffolds to identify an iron/benzimidazole-based metal–organic framework as uniform material. By merging catechol and imidazole units together, we get direct entry into highly efficient bifunctional oxygen electrocatalyst, which alleviates need for dopants modifying conditions. demonstrate that by...
Multifunctional electrocatalysts are vastly sought for their applications in water splitting electrolyzers, metal-air batteries, and regenerative fuel cells because of ability to catalyze multiple reactions such as hydrogen evolution, oxygen reduction reactions. More specifically, the application single-atom electrocatalyst multifunctional catalysis is a promising approach ensure good atomic efficiency, tunability additionally benefits simple theoretical treatment. In this review, we provide...
