Integrated CO₂ capture-fixation chemistry via interfacial ionic liquid catalyst in laminar gas/liquid flow.

ABSTRACT: Simultaneous capture of carbon dioxide (CO₂) and its utilization with subsequent work-up would significantly enhance the competitiveness of CO₂-based sustainable chemistry over petroleum-based chemistry. Here we report an interfacial catalytic reaction platform for an integrated autonomous process of simultaneously capturing/fixing CO₂ in gas-liquid laminar flow with subsequently providing a work-up step. The continuous-flow microreactor has built-in silicon nanowires (SiNWs) with immobilized ionic liquid catalysts on tips of cone-shaped nanowire bundles. Because of the superamphiphobic SiNWs, a stable gas-liquid interface maintains between liquid flow of organoamines in upper part and gas flow of CO₂ in bottom part of channel. The intimate and d
