Congratulations to Jisoo Park on successfully defending her M.S. thesis, entitled “Poly(biphenyl piperidine)-Based Anion-Exchange Membranes with Transport-Effective Hydration for Zero-Gap CO2 Electrolysis.” We wish her all the best in her future endeavors!
Young In Song and colleagues publish in ACS Catalysis, “Ionomer Charge Density Modulates Interfacial Water and Reaction Intermediates for CO2 Electrolysis to C2 Products.” We show that tuning ionomer charge density shapes interfacial water structure and key reaction intermediates, thereby enhancing selectivity and activity for electrochemical CO2 reduction to C2 products and advancing design principles for catalyst–ionomer interfaces.
A huge thank you to the lead authors, Young In Song and Shedrack Akpe, and to our collaborators, Bohak Yoon, Hyo Sang Jeon, and Jung Kyu Kim, for this joint work.
Young In and Jihyun gave excellent presentations on ionomeric materials for electrochemical CO2 reduction. Keep up the good work!
Congratulations on this recognition of your dedication and effort. Wishing her continued success in future research pursuits. Very much well-deserved! 🥳
Jihyun Park and colleagues publish in ACS Catalysis, “Ionomer Side Chains Modulate Interfacial Microenvironments for Selective CO2 Electrolysis.” We demonstrate how imidazolium ionomers with varied linear alkyl side chains reshape catalyst–electrolyte interfaces to suppress hydrogen evolution and enhance CO2 electrolysis performance, linking side-chain structure to activity and selectivity in electrocatalytic systems.
Congratulations to Jihyun for receiving the Best Poster Presentation Award at the Nano Convergence Conference (NCC) 2025! Your hard work and commitment have been recognized. Wishing you even greater achievements in your research journey ahead! 🎉👏✨
Your dedication has truly paid off. Congratulations! Special thanks to his thesis advisor, Prof. Jung Kyu Kim, and collaborators, Prof. Bohak Yoon, Chanwoo Lee, and Dr. Hyo Sang Jeon. Wishing you continued success in your future research endeavors. 🎉🥳👏
Young In Song and colleagues publish in Advanced Science, “Impact of Side Chains in 1-n-Alkylimidazolium Ionomers on Cu-Catalyzed Electrochemical CO2 Reduction.” We report that tailoring the alkyl side chain lengths in 1-n-alkylimidazolium ionomers modulates product selectivity in Cu-catalyzed electrochemical CO2 reduction. This strategy suppresses H2 and CH4 formation and enhances C2H4 selectivity with industrial-relevant metrics, providing design insights for ionomer-mediated CO2 conversion.
