Preparation of electrocatalysts by reduction of precursors with sodium citrate
Briskeby, Stein Trygve; Tsypkin, Mikhail; Tunold, Reidar; Sunde, Svein (Journal article; Peer reviewed, 2014)In this work synthesis of Pt/C catalysts by reduction of H2PtCl6 with sodium citrate has been investigated. The strong pH-dependence of citrate as a reducing and stabilizing agent has been explored, and an optimum pH range ... -
Stability of carbon nanofibre-supported platinum catalysts in the presence of chloride under controlled mass-transfer conditions
Briskeby, Stein Trygve; Tsypkin, Mikhail; Tunold, Reidar; Sunde, Svein (Journal article, 2014)The effect of chloride on the stability of platinum electrocatalysts was studied by rotating disk measurements in sulfuric acid electrolyte with a continuously increasing concentration of chloride anions. The activity ...
