High-permeance polymer-functionalized single-layer graphene membranes that surpass the postcombustion carbon capture target

Mounir Driss Mensi, Emad Oveisi, Kumar Varoon Agrawal, Shiqi Huang, Guangwei He, Jing Zhao, Luis Francisco Villalobos Vazquez de la Parra

Membrane-based postcombustion carbon capture can reduce the capture penalty in comparison to absorbent-based separation. To realize this, high-performance membranes are urgently needed with a CO2 permeance exceeding 1000 gas permeation units or GPU, and a ...

Molecular tunability of surface-functionalized metal nanocrystals for selective electrochemical CO2 reduction

Mounir Driss Mensi, Raffaella Buonsanti, Yannick Thomas Guntern, James Richard Pankhurst

Organic ligands are used in homogeneous catalysis to tune the metal center reactivity; in contrast, clean surfaces are usually preferred in heterogeneous catalysis. Herein, we demonstrate the potential of a molecular chemistry approach to develop efficient ...
