Abstract Direct ethanol fuel cells (DEFCs) play an indispensable role in the cyclic utilization of carbon resources due to its high volumetric energy density, efficiency, and environmental benign character. However, owing chemically stable carbon‐carbon (C─C) bond ethanol, incomplete electrooxidation at anode severely inhibits power density output DEFCs. The efficiency C─C cleaving on state‐of‐the‐art Pt or Pd catalysts is reported as low 7.5%. Recently, tremendous efforts are devoted this...
To construct a suitable three-dimensional structure for ionic transport on the surface of active materials supercapacitor, porous hollow nickel cobalt sulfides are successfully synthesized via facile and efficient cation-exchange reaction in hydrothermal process involving Kirkendall effect with γ-MnS nanorods as sacrificial template. The formation mechanism is carefully illustrated tuning time temperature during process. Due to ingenious that offers high area electrochemical paths transport,...

The design of a low-platinum (Pt) proton-exchange-membrane fuel cell (PEMFC) can reduce its high cost. However, the development low-Pt PEMFC is severely hindered by oxygen transfer resistance in catalyst layer.

Abstract The development of low‐cost non‐precious‐metal electrocatalysts with high activity and stability in the oxygen reduction reaction (ORR) remains a great challenge. Heteroatom‐doped carbon materials are receiving increased attention research as effective catalysts. However, uncontrolled doping heteroatoms into matrix tends to inhibit catalyst. Here, situ activation uniquely structured nitrogen‐doped carbon/Ni composite catalyst for ORR is demonstrated. This well‐designed composed...
