Coal electro‐oxidation in sodium hydroxide solution with catalysts, K3Fe(CN)6, sodium hypochlorite and supported FeS, were investigated, respectively. Gas produced from electro‐analysis of coal slurry was collected by drainage‐method and I‐t curves were recorded to testify the catalysis of each catalyst for coal oxidation. The results show that the three kinds of catalysts can obviously improve the...
A TiO2/Pt based electrode exhibited better activity for the oxidation of coal in a basic system compared to Ti/Pt, TiO2–Cu/Pt and pure metal electrodes. The surface morphologies and composition of the electrodes were studied by SEM and XRD, respectively. Linear sweep voltammetry was employed to investigate the catalytic effects of electrodes, and the product of coal oxidization was determined by a...
