The Anode in the Direct Methanol Fuel Cell

, 2003
The direct methanol fuel cell (DMFC) is a very promisingpower source for low power applications. High power and energydensity, low emissions, operation at or near ambientconditions, fast and convenient refuelling and a potentiallyrenewable fuel source are some of the features that makes thefuel cell very promising. However, there are a few problemsthat

Symmetry Breaking of FeN4 by Interlaminar Oxygen‐Bonded Vacancy Defect Toward Efficient Oxygen Reduction Reaction

EcoEnergy, EarlyView.
The adjacent vacancy defect bonded with interlaminar oxygen breaks the symmetry of FeN4 active site, facilitating the *OH desorption and lowering the reaction overpotential, ultimately enhancing the intrinsic catalytic activity of the Fe center. ABSTRACT Developing highly efficient non‐noble iron‐nitrogen‐carbon (Fe‐N‐C) catalysts with FeN4 active ...

A Mixed‐Ligand Metal–Organic Framework Strategy to Construct High‐Density O/S‐Shelled Ag Nanoparticle Electrocatalysts for Syngas Modulation

EcoEnergy, EarlyView.
Mixed‐ligand Ag–triazole MOF precursors reconstruct into ligand‐shelled Ag nanoparticle electrocatalysts that retain detectable O/S‐derived interfacial species. By combining ligand‐ratio and potential control, the CO2‐to‐syngas output can be tuned across H2‐rich, near‐equimolar, and CO‐rich regimes.
