A Hybrid Assembly with Nickel Poly‐pyridine Polymer on CdS QDs for Photo‐reducing CO2 into Syngas with Controlled H2/CO Ratios

A hybrid photocatalytic assembly with Ni poly-pyridine polymers binding on CdS quantum dots is developed via thiophene immobilization. The fabricated hybrid assembly fascinates efficient charge separation, and each component endows great synergy. As a result, a high syngas production rate is achieved over 5500 µmol g (cat)−1 h−1 from photocatalytic CO2 reduction under visible-light irradiation, accompanied by an adjustable H2/CO ratio ranging from 4: 1 to 1: 3. Here, we described a novel hybrid assembly for syngas synthesis with boosted activity and controlled selectivity, which provides a profile to ingeniously understand molecular-level design for photocatalyst.
