Electrocatalytic reduction of carbon dioxide using sodium pectate with manganese in an aqueous solution of KHCO3

Abstract

Relevance of the research topic is due to the global trend towards the development of clean energy, in particular, the utilization of carbon dioxide. Recently, electrocatalytic reduction of carbon dioxide has been considered as a promising way to utilize carbon resources and produce sustainable fuels. Due to the limited energy efficiency, uncontrolled selectivity, low stability, and uncertain mechanisms of electrocatalytic CO2 reduction, there are still many complex problems to be solved. In this regard, current research in the field of electroreduction of CO2 is relevant. Sustainable and cheap catalysts need to be developed for the electroreduction of carbon dioxide. This paper presents a review on sodium pectate with manganese as a catalyst in the carbon dioxide reduction reaction. It was experimentally proven that sodium pectate with manganese exhibits catalytic properties in carbon dioxide reduction as the overvoltage was reduced by 400 mV. The stability of this complex was also tested for some time, the current for 8 hours increases, which means that sodium pectate with manganese can maintain its catalytic activity in the carbon dioxide reduction reaction for a long time. In the future, this complex can replace other more expensive catalysts.
