To solve the problems such as high pollution and high consumption existing in the traditional production technique of potassium dichromate, a new green technology of electrocatalytic synthesis of potassium dichromate was studied. Cyclic voltammetry has been used to investigate the electro-catalytic performance of anode, and the morphology and structure of anode were characterized by FESEM. The results indicated that the Ru/Ir/Ti oxide composite anode exhibits lower oxygen evolution potential in anolyte and stable high electrocatalytic activity. The hydrogen evolution rates of cathode at different reaction conditions were experimentally measured in the electrocatalysis synthesis process of potassium dichromate. The mathematical models were established for the dependence of hydrogen evolution rate and hydrogen evolution amount on initial potassium chromate concentration, reaction temperature, and reaction time. It was pointed out that the cathodic hydrogen evolution quantitatively measured may be used to characterize the electrocatalytic reaction process of potassium dichromate, and the influencing factors of hydrogen evolution rate and hydrogen evolution amount were discussed.
