Inside–Outside Nanotube Catalyst Channels Sunlight into Directional Electron Flow for CO₂ Conversion

Caption

A molecularly compartmentalized photocatalyst with Fe-porphyrins on CNT exteriors and Ni-POMs inside channels enables vectorial electron transfer. Photoexcited electrons travel unidirectionally through CNTs to NiPOMs, efficiently driving CO2 to CO conversion with a 100% selectivity. This biomimetic architecture mimics natural photosynthesis, enhancing charge separation and achieving superior photocatalytic CO2 reduction under light.
