“…Titanium is the usual substrate for applications although an Indian group have promoted graphite [62][63][64][65][66][67][68][69][70] and some papers have suggested tantalum 71 and ebonex. [72][73][74] Adhesion of the PbO 2 coating to titanium is, however, a problem. Certainly, the titanium, usually in the form of a plate or expanded metal mesh, must be pretreated before the anodic plating process 8,75,76 in order to remove existing TiO 2 scale from the surface and roughen the surface and to prevent passivation.…”

“…63 The literature on the electrochemical deposition of pure lead dioxide is very extensive. It is clear that the adhesion, surface morphology, ratio of a/b forms and catalytic activity can be influenced by many parameters including 8,24,46,60,74,[83][84][85][86][87][88][89][90][91] the substrate (Pt, Au, graphite, glassy carbon, Ti, Ti with undercoat, Ta).…”

“…4 Quando hidratado, o PbO 2 é classificado como um condutor do tipo metálico (possuidor de elevada densidade eletrônica, 10 20 a 10 21 cm -3 ). 4 Essa condutividade se deve à não estequiometria do óxido que envolve vacâncias de oxigênio 5 ou à substituição de oxigênios superficiais por grupos hidroxilas como resultado da hidratação dos filmes, 6 representada por PbO 2-x (yH 2 O), onde 2-x é o grau de desvio da estequiometria ideal e yH 2 O representa a quantidade de água presente na estrutura do óxido.…”
