Enhanced photocatalytic CO conversion of a CdS/Co-BDC nanocomposite Co(ii)/Co(iii) redox cycling.

Photocatalytic CO reduction into value-added chemical fuels using sunlight as the energy input has been a thorny, challenging and long-term project in the environment/energy fields because of to its low efficiency. Herein, a series of CdS/Co-BDC composite photocatalysts were constructed by incorporating CdS nanoparticles into Co-BDC using a dual-solvent growth strategy for improving photocatalytic CO reduction efficiency. The composites were characterized through XRD, SEM, TEM, XPS, DRS and EPR techniques in detail.
