In this context, worldwide efforts have been dedicated to developing non-precious-metal and carbon-based metal-free electrocatalysts (C-MFECs) to either replace or reduce the need for precious metals.2,3 C-MFECs own many advantages compared with their metal counterparts, such as their abundance...
Such theoretical and experimental evidences of intrinsic defect-induced activity can reveal the active centers and relevant catalytic mechanism, thereby providing necessary guidance for the design and construction of highly efficient carbon-based electrocatalysts and promoting their commercial applications. 展开...
Carbon based electrocatalysts have shown promising portfolios over the years. They provide good mechanical strength, increased active surface area, and enhanced conductivity at a lower cost. The problem however is their low activity. So, composites of carbon based materials are made with other establis...

This section examines various copper-based electrocatalysts (copperselenide, single-atom alloyedCu alloys, e.g., with Pb, Bi, Pd, or In, and copper modified with a protecting graphene layer), supportedcopper catalysts(such as Cu on TiO2), and bimetallic catalysts. Surveyed are the microstructure...
This invention describes the preparation of electrocatalysts to be mounted at either the anode or the cathode of fuel cells or of H2 electrolysers. The materials described in this invention are particularly suitable for application in polymer electrolyte membrane fuel cells (PEMFCs), direct methanol...
The N-rich porous carbons are effective electrocatalysts, as shown by both half-cell and full-cell measurements. They are promising replacements of the Pt-based ORR catalyst in alkaline Zn–air batteries. Importantly, the 3D mesoporous network structure was highly favourable for rapid ORR species ...
