Research on the Influence of Magnesium Based Carbon Dioxide Battery System on Carbon Dioxide Conversion Performance
At present,energy consumption and carbon emissions in the shipping industry are becoming increasing-ly severe.In order to reduce greenhouse gas emissions from ships and achieve the medium-and long-term strategic goals of carbon reduction in the shipping industry,CO2 capture and storage technology(CCS)has become an im-portant means.However,this technology has problems such as high energy consumption,large space occupation,and high transportation and processing costs in the liquefaction and storage stages.Therefore,developing low en-ergy and compact CO2 storage technology is the key to promoting the development of ship CCS technology.This paper introduces a magnesium based carbon dioxide battery system that converts and utilizes CO2,achieving CO2 storage while also producing new energy sources such as hydrogen.Through the preparation of efficient catalytic electrodes and the testing of the effect of CO2 flow rate on battery performance,the optimal process parameters were determined to be Pd/CeO2 oct electrode,0.5mol/L NaOH electrolyte solution,and CO2 flow rate of lL/h.The battery system exhibited high cycling stability under a current density of 8mA/cm2 for 600 minutes(20 charge dis-charge cycles),with a hydrogen production of 10.135mL and a Faraday efficiency of 97.03％.
