wolleSunさんは、地球上の良好な炭素循環およびカーボンニュートラルの実現の鍵を握る、CO2還元を効率よく進めるための電極触媒の開発を行なっています。無極性で反応性の低いCO2を変換するには高度の触媒技術が必要になります。Sunさんは、根気よく研究に取り組み、独自のアイディアで高い活性を示す触媒の開発とその機構の解明に成功しています。今後は、さらに研究を深めて高性能触媒を作製するとともに、脱炭酸フェローシップの取り組みの中での学びや交流を活かして、世界で活躍する研究者になってほしいと期待しています。8Q-Energy Innovator Fellowship理学府化学専攻博士後期課程3年先導物質化学研究所 教授This is Sun Mingxu. With the gradual increase in greenhouse gas carbon dioxide (CO2) emissions, the world is facing more and more serious climate problems, and reducing carbon emis-sions is therefore of great significance. As well as reducing carbon emissions, capturing CO2 and converting it into valuable prod-ucts makes it more valuable on the market. The CO2 molecule is linear and centrosymmetric, and the dissociation energy of its C=O double bond is higher than that of other carbonyl functional groups. The valence of Carbon, the central atom of CO2, is 4, the highest valence state of carbon. CO2 cannot be oxidized but can only be reduced. Electrochemical reduction of CO2 is a current research hotspot. The reduction of CO2 on the cathode surface is achieved by controlling the voltage. The reaction conditions are mild, easy to control, simple to operate, and do not require H2 as a reaction raw material, and it is easy to achieve large-scale applications.My research focuses on the electrocatalytic conversion of CO2 to carbon fuels. The specific research includes the following three aspects:1. Mechanism of the electrocatalytic process: We can better un-derstand electrocatalytic reaction processes using advanced in-situ characterization techniques and mechanism research methods.2. Catalyst design: The use of novel mechanistic discoveries al-lows us to rationally design catalysts with unique compositions, electronic structures, and surfaces.3. Reactor design: The design and optimization of electrocatalytic devices allows us to enhance catalytic performance to a level that meets the demands of practical applications.指導教員からメッセージThe reactor of electrocatalytic CO2 reduction assembly in progress山内 美穂Electricity-driven CO2 Conversion to Value-add-ed ChemicalsElectrochemical CO2 Conversionto Value-added ChemicalsSun Mingxu03f
