The morphological control of Co3O4 by polyvinylpyrrolidone during precipitation reaction has resulted in the formation of two-dimensional nanodisks with surface porosity. As a bi-functional catalyst, Co3O4 nanodisks are active towards both the oxygen

Phosphorus and Co co-doped mesoporous carbon (P–Co-MC) has been prepared using a soft template. The P–Co-MC exhibits high catalytic activity comparable to commercial Pt/C and long-term stability for the oxygen reduction reaction (ORR) in basic me

Determination of the so-called onset potentials, i.e. the lowest (for the anodic reactions) or the highest (for the cathodic reactions) potentials at which a reaction product is formed at a given electrode and at defined conditions, is very important

The identification of rate-determining step (RDS) is vital for understanding reaction mechanisms and designing advanced catalysts. Here, we systemically studied the H–D kinetic isotope effects (KIEs) on electrooxidation of ethanol, isopropanol, and

The different atomic arrangements of noble metal nanocrystals with varying facets will largely affect the catalytic activity. Rhombic dodecahedral, octahedral, cubic Pd single-nanocrystalline crystals are exclusively enclosed by {100}, {111}, and {11

A passive-type air-breathing biocathode using bilirubin oxidase as enzyme, ferricyanide as redox mediator, and poly-l-lysine as linker was investigated. Water-repellents from Scotchgard™ with dissolved in methyl isobutyl ketone were directly applie

Previously, mathematical modeling of a proton exchange membrane fuel cell has failed to precisely predict the performance in low relative-humidity operations. Herein, we report the fit parameters for water-uptake isotherm of the catalyst layer based

We show in this study that the presence of trace metal residues in some supposedly metal-free catalysts for oxygen reduction, at concentrations which are difficult to detect using conventional methods such as XPS and EDX, can profoundly promote the O

We report the first example of a glucose/H2O2 biofuel cell operating at 5 mM glucose under air at 37 °C in 0.14 M NaCl. At a bienzymatic cathode, the direct wiring of horseradish peroxidase (HRP) achieves the electrocatalytic reduction of H2O2 conco
