The immobilization, protection, and electrical wiring of sensitive catalysts by specifically designed supporting matrixes are of particular importance for technological relevant applications. Here, we describe the protection of a DuBois-type H 2 oxidation catalyst, which was covalently bound to an inert polymer matrix, against molecular O 2 by forming blends together with an O 2 -reducing redox polymer matrix. This matrix simultaneously acts as an electron relay for shuttling electrons between the catalyst and the electrode. © 2019 American Chemical Society.
