In this work, the yields of CO2 and acetic acid are studied as a function of the roughness of PtRu electrodeposits of fixed atomic composition during the electrooxidation of ethanol in the presence of 0.1 M HClO4. Based in the findings of a previous

There are three possible cases of the initial electro-dissolution reactions of bare copper in acid/neutral chloride media. Two of them involve the direct formation of a cuprous chloride species from the metal, while the other, the dissolution of copp

This work shows that it is possible to obtain self-standing Pd nanowires into anodic alumina membranes by a simple metal displacement deposition. By using a proper arrangement, specifically designed in order to optimize the process, polycrystalline P

A new approach is proposed in order to perform electrochemical oxidation of organics by working under galvanostatic conditions with the potential ‘buffered’ by the competing side reaction of oxygen evolution (OER). According to this process the w

High, electrochemically controlled electrical conductivity (0.2–0.3 S cm−1) was measured for the first time for the metal–metal bonded polymeric compound [Ru(bpy)(CO)2]n (bpy = 2,2′-bipyridine). The conductivity depended on the degree of part

Pitfalls of the phase-shift method for determining adsorption isotherms in the case of two-step Faradaic reactions involving adsorption at transition metals (alloys)/aqueous solution interfaces are discussed following the recent publication of the pa

Platinum stepped surfaces vicinal to the (1 1 0) crystallographic pole have been investigated voltammetrically in 0.1 M HClO4 and 0.1 M H2SO4 solutions. Changes in the voltammetric profile with the step density suggest the existence of two types of s

We report an unusual and not previously reported adsorption state of CO on a Au(1 1 1) electrode and a hexagonally reconstructed Au(1 0 0) surface. Chemisorbed CO exhibits a reversible adsorption feature close to the onset of the oxidation of CO in s

Electrochemical oxidation of freshly deposited Pd and its alloys with other noble metals (Au, Pt, Rh) was compared with the behavior of samples subjected to prior hydrogen absorption/desorption procedure. It was found that surface oxidation of hydrog

In this work, an ultrasensitive platform for the detection of cadmium (Cd2+) combining the nafion–graphene nanocomposite film with differential pulse anodic stripping voltammetry (DPASV) analysis was presented. It is found that this sensing platfor
