A novel green system for the electrochemical oxidation of alcohols is demonstrated using a column flow cell. Voltammetric analysis revealed that the oxidation of 1-phenylethanol and benzaldehyde are promoted by using both an Au-electrode and an alkal

The polarization mechanism of capacitive-faradaic fuel cells is reported. The mixed potentials of faradaic (Pt and Ti/Pt-IrO2) and capacitive (activated carbon powder and fleece) electrodes were measured in aerated and hydrogenated NaCl solutions at

Three different metal oxides based on Mn2O3 with TiO2 or NiO were synthesised. Pt or PtNi nanoparticles were anchored on each support, creating a set of nine samples that were tested for the oxygen reduction reaction (ORR) and the oxygen evolution re

In this study, highly ordered anodic porous metal oxides of transition metals (W, Fe, Co, and Nb) were prepared by anodization combined with a pretexturing process. The formation of an array of dimples on the metal surface was achieved by dry etching

The performance of a direct methanol fuel cell (DMFC) is strongly dependent on the catalytic anode. A high-performance anode is expected to offer enhanced intrinsic activity and/or a large electrochemical surface area. Herein, a series of Ag-core/Pd-

Electroreduction of CO2 to fuels or valuable chemicals is a promising way to mitigate the greenhouse effect. Herein, ultrathin In2Se3 nanosheets are reported as a robust catalyst for CO2-to-CO conversion with a faradaic efficiency of 89% and a stable

Trichloroethylene (TCE) is a toxic carcinogen. Electrocatalytic hydrodechlorination is a very effective and safe method for degrading TCE and does not produce any secondary pollution. In this communication, a new cathode, fabricated by loading cataly

Cu is the only electrocatalyst that converts CO2 into appreciable quantities of hydrocarbons. However, it usually suffers from poor catalytic stability. In this work we propose a strategy of introducing crystal defects to change the reaction pathway

A label-free strategy for imaging blood fingermarks (BFMs) on a hydrophobic poly(vinylidene difluoride) (PVDF) membrane has been developed using scanning electrochemical microscopy (SECM) in the surface interrogation (SI) mode. In this approach, hexa
