Functional compartmentalization in asymmetric Co–Ni microenvironment for selective <scp> CO <sub>2</sub> </scp> ‐to‐ <scp> C <sub>2<
Photocatalytic CO 2 ‐to‐C 2 H 4 conversion faces a kinetic paradox in which enriching C 1 intermediates for C–C coupling inherently compromises their hydrogenation and product release due to strong surface binding. Here, we resolve this paradox through sulfur‐vacancy (Vs) engineering in CoNi 2 S 4 nanos...
