AbstractElectrochemical reduction of CO2 on various types of catalysts has been investigated intensively as a possible way to convert waste CO2 to useful products and thus contributing to the effort of limiting climate change. Porphyrins and phthalocyanines are known to be very promising catalysts for CO2 electroreduction but their corresponding nanostructures have not thus far been investigated.1 Herein, we report the growth of Co(III)TPPCl nanofibers (20-100 nm in diameter) on gas diffusion layers via an evaporation induced self-assembly (EISA) method as shown in Fig. 1.2 Remarkably, as-fabricated electrodes demonstrate light-enhanced activity for CO2 reduction to CO as evidenced by cyclic voltammograms and electrolysis with/without light irradiation. To the best of our knowledge, it is the first time that such a light-enhanced CO2 reduction effect based on nanostructured cobalt(III) porphyrin catalysts has been observed. Gas chromatography (GC) verifies that light irradiation can improve CO production by up to 31% during 2 hours of electrolysis. Studies on the mechanism of light enhanced CO production are on-going. In addition, a variety of novel porphyrin nano- or micro-structures comprising cobalt(III) porphyrins were also prepared, such as microcrosses with tunable structural features at the nano-scale.
