Microchannel reactor is a novel electrochemical device to intensify CO mass transfer with large interfacial areas. However, if the catalyst inserted in the microchannel is wetted, CO is required to diffuse across the liquid film to get access to reaction sites. In this paper, a hydrophobic polytetrafluoroethylene (PTFE)-doped Ag nanocatalyst on a Zn rod was synthesized through a facile galvanic replacement of 2Ag+Zn → 2Ag + Zn.

To explore the potential application in this direction, AG was prepared to be used as the cathode in COelectroreduction to CO. However, the gelation time of NMAs is usually very long, up to several weeks.
