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 h from photocatalytic CO reduction under visible-light irradiation, accompanied by an adjustable H /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.
通过噻吩固定化制备了一种在硫化镉量子点上结合镍多吡啶聚合物的混合光催化组件。所制备的混合组件促进了高效的电荷分离，且各组分具有很强的协同作用。结果，在可见光照射下，通过光催化CO还原实现了高达5500 μmol g⁻¹ h⁻¹的合成气高产率，同时H₂/CO比可在4 : 1至1 : 3范围内调节。描述了一种用于合成气合成的具有增强活性和可控选择性的新型混合组件，它为巧妙理解光催化剂的分子水平设计提供了一个范例。
