Abstract
Abstract A hybrid photocatalytic assembly with Ni poly‐pyridine polymers binding on CdS quantum dots was developed via thiophene immobilization. The fabricated hybrid assembly facilitated efficient charge separation, and each component endowed great synergy. As a result, a high syngas production rate was achieved over 5500 μmol g cat −1 h −1 from photocatalytic CO 2 reduction under visible‐light irradiation, accompanied by an adjustable H 2 /CO ratio ranging from 4 : 1 to 1 : 3. A novel hybrid assembly was described for syngas synthesis with boosted activity and controlled selectivity, which provides a profile to ingeniously understand molecular‐level design for photocatalysts.
