Abstract Direct photocatalytic CO 2 reduction from primary sources, such as flue gas and air, into fuels, is highly desired, but the thermodynamically favored O almost completely impedes this process. Herein, we report on efficacy of a composite photocatalyst prepared by hyper-crosslinking porphyrin-based polymers hollow TiO surface subsequent coordinating with Pd(II). Such exhibits high resistance against inhibition, leading to 12% conversion yield air after 2-h UV-visible light irradiation. In contrast, over Pd/TiO without polymer severely inhibited presence ( ≥ 0.2 %).
