“…In-situ XAS experiments were carried out in 1.0 M H 2 SO 4 at room temperature. Working electrodes were prepared by applying the catalyst paste mixed with polytetrafluoroethylene (PTFE) onto carbon paper as described in our report, 30 and Ag/AgCl and Pt wire were used as reference and counter electrode, respectively. X-ray absorption spectra were recorded before and after CO adsorption.…”

“…A caracterização eletroquímica dos catalisadores de Pt/C foi feita através de voltametrias cíclicas (VC's) para elucidar as propriedades superficiais dos materiais e determinar a área eletroquimicamente ativa [5,16,18]. O catalisador suportado foi misturado a uma pequena quantidade de PTFE (Teflon TM30, Du Pont), acomodado na cavidade de um eletrodo de camada fina porosa (eletrodo de trabalho) e acoplado a um sistema comercial de eletrodo de disco rotatório (PINE Instruments).…”

“…A voltametria cíclica tem sido muito utilizada para caracterizar catalisadores de Pt lisa [25], platina e ligas bimetálicas Pt-M [M = Co, Cr e Ni] suportadas em carbono [16,18], com o intuito de determinar a área eletroquimicamente ativa e também para caracterizar as propriedades superficiais dos eletrodos [5].…”
