Abstract A new type of zeolitic imidazolate framework ZIF-8/TiO nanocomposites was developed for photocatalytic reduction of CO to CH and CO in a newly designed photoreactor under intentionally controlled pressure swing. The ZIF-8/TiO core-shell structure plays an important role in the adsorption of CO by ZIF-8 and subsequent in-situ photocatalytic reduction on TiO. The introduction of pressure change in the reaction system facilitates the adsorption-desorption process of CO and reaction products, which consequently led to improved photoreduction performance. This approach highlights the importance of mass transfer and reactor design for improved photoreduction.
