通过噻吩的固定，制备了一种以CdS量子点为载体的Ni-聚吡啶聚合物杂化光催化组装体。所制造的混合组装体促进了有效的电荷分离，并且每个组分赋予了很大的协同作用。因此，在可见光照射下，通过光催化CO2还原实现了超过5500 μmol gcat−1h− 1的高合成气生产率，并伴随着可调节的H2/CO比，范围为4：1至1：3。 描述了一种用于合成气合成的新型混合组装体，其具有增强的活性和受控的选择性，这为巧妙地理解光催化剂的分子水平设计提供了一个轮廓。
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 gcat−1h−1from photocatalytic CO2reduction under visible‐light irradiation, accompanied by an adjustable H2/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.
