Construction of a graphitic carbon nitride-based photocatalyst with a strong built-in electric field via π–π stacking interactions boosting photocatalytic CO2 reduction

A high-efficiency photocatalyst with a strong built-in electric field was fabricated by anchoring π-conjugated molecules on the surface of crystalline nitride carbon via π–π stacking interactions with efficient photocatalytic CO 2 reduction into CO and CH 4 .
