In this study, we use a combination of kinetic isotope effect and proton inventory studies to explain the observed increase in activity and selectivity upon polymer encapsulation. We provide evidence that axial-coordination from the pyridyl moieties in poly-4-vinylpyridine to the cobalt phthalocyanine complex changes the rate-determining step in the CO<sub>2<\/sub> reduction mechanism accounting for the increased activity in the catalyst-polymer composite. Moreover, we show that proton delivery to cobalt centers within the polymer is controlled by a proton relay mechanism that inhibits competitive hydrogen evolution. These mechanistic findings provide design strategies for selective CO<sub>2<\/sub> reduction electrocatalysts and serve as a model for understanding the catalytic mechanism of related heterogeneous systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s41467-019-09626-8 Authors: Yingshuo Liu, Charles C.
