Janus electrocatalytic flow-through membrane enables highly selective singlet oxygen production
2020
Overview
The importance of singlet oxygen (

) in the environmental and biomedical fields has motivated research for effective
1
O

production. Electrocatalytic processes hold great potential for highly-automated and scalable

synthesis, but they are energy- and chemical-intensive. Herein, we present a Janus electrocatalytic membrane realizing ultra-efficient
1
O

production (6.9 mmol per m

of permeate) and very low energy consumption (13.3 Wh per m
3
of permeate) via a fast, flow-through electro-filtration process without the addition of chemical precursors. We confirm that a superoxide-mediated chain reaction, initiated by electrocatalytic oxygen reduction on the cathodic membrane side and subsequently terminated by H

O

oxidation on the anodic membrane side, is crucial for
1
O

generation. We further demonstrate that the high
1
O
2
production efficiency is mainly attributable to the enhanced mass and charge transfer imparted by nano- and micro-confinement effects within the porous membrane structure. Our findings highlight a new electro-filtration strategy and an innovative reactive membrane design for synthesizing

for a broad range of potential applications including environmental remediation.
Electrocatalytic processes are promising for automated and scalable synthesis of singlet oxygen, but they are energy- and chemical-intensive. Here the authors present a Janus electrocatalytic membrane that selectively produces singlet oxygen with low energy consumption and free of chemical precursors.
