The experimental evidence and mechanism of ‘hydrogen spill-over’ on Pt/WO3 is reviewed and the application of this catalyst system for the evolution of hydrogen, anodic oxidation, hydrogenation and the anodic oxidation of small molecules and impu

There are two modes of operation for an aluminium/water battery: use of hydrogen-evolving or oxygen-reduction cathodes. In the first case, the current density is ≈10 mA cm −2 at 0.5 V. This leads to significant increase of pH and deposition of Ca

The implications of the substitution of nickel for cobalt in Co3O4 to give Co2NiO4 are discussed. From the effects of substitution of other ions into Co2NiO4 its curious properties may partly be understood. The cations present are unable to satisfy t

The addition of reducing agents such as hydrazine or sodium sulphite to buffered dilute copper solutions containing chloride ions reduces cupric ions to cuprous ions chemically, thus by-passing this rate-determining electrochemical step. The subseque

Steady-state and potentiostatic transient H 2 evolution studies on Teflon bonded Pt black, platinized Pt and Pt foil electrodes in 5 N H 2 SO 4 , 25°C showed that teflon bonded electrodes gave a higher performance than the other electrodes. The pres

The kinetics, in alkaline solution, of heterogeneous H 2 O 2 decomposition by the cobalt-iron spinel oxide system, Co x Fe 3 − x O 4 , (0 ≤ x ≤ 3), were studied with a view to defining the intrinsic and microstructural factors influencing the c
