In this paper, a new approach for the preparation of dimensionally stable anodes DSA(R) type oxide electrodes, using a CO2 laser as a heat source, is proposed. Commercial composition of (TiO2)(0.7)(RuO2)(0.3) was used for this feasibility study in which thermal decomposition of precursor chlorides, for the growth of a coating 2-3 mum thick, is carried out in 30 min. The resulting oxide layer presented the usual cracked-mud morphology that lasted 8 h in an accelerated service life test at 400 mA cm(-2), in a H2SO4 1 M solution. The results involving the effects of laser beam power and scan rate are examined. Voltammetric anodic charge was maximized by the combination of 15 W beampower, focal distance of 210 mm and beam scan rate of 35 mm s(-1). By cycling potential between 0.2 and 1.1 V vs SCE the oxide coating behaved as a capacitor capable of being charged and discharged reversibly and the cathodic/anodic charge ratio remained close to one. Currents related to oxygen evolution reaction were observed after 1.37 V vs SCE. (C) 2002 Elsevier Science B.V. All rights reserved.42139142
