“…Indeed, even if the electrodeposition of pure oxides thin films of various materials [2,[28][29][30] and lead in particular [31,32] is already largely reported in the literature for synthesis and/or for various applications (e.g. (electro)catalysis [13,33,34]), no study focusses on the depollution of aqueous solutions as reported today in this article.…”

“…The decolorization processes for both electrodes followed the pseudo-first-order model [36,37], and the kinetics curves are shown in the inset. The rate constant of MB by Ti/α-PbO 2 /β-PbO 2 electrode was 0.077 min −1 , which was about 5 times that of Ti/α-PbO 2 electrode (0.015 min −1 ) [38,39].…”

“…This can be explained by the rapid reaction of hydroxyl radicals with MB molecules at the electrode at the voltages without oxygen evolution. Thus, a relatively high concentration of MB (9 mg L −1 ) was chosen as the optimum initial concentration [38,39].…”

“…Na condição ótima, determinada por meio de um planejamento experimental, 0,1 mol L -1 de Na 2 SO 4 , temperatura em 35 °C e aplicando uma densidade de corrente de 20 mA cm -2 obteve--se 100 % de remoção de 2-clorofenol em 180 min. 27 Para desenvolver uma metodologia para a preparação de eletrodos de óxidos os seguintes requisitos devem ser atendidos: construção rápida e simples; suporte metálico barato e com boa condutividade elétrica; o recobrimento dos óxidos devem ter uma espessura fina e alta atividade eletrocatalítica e, por fim, o eletrodo deve alcançar uma alta estabilidade química e física. Os eletrodos de óxidos podem ser preparados a partir da eletrodeposição anódica, deposição química a vapor ou, mais comumente utilizado, pela técnica de decomposição térmica.…”
