Self-assembled copper/cobalt-containing polypyrrole hydrogels for highly efficient ORR electrocatalysts

The exploitation of high-efficiency, inexpensive, as well as durable electrocatalysts for the oxygen reduction reaction (ORR) is of vital importance for a number of emerging technologies, such as fuel cells to counter energy and environment crises. Herein, we describe a novel approach for the synthesis of conducting electrocatalysts derived from copper/cobalt-containing polypyrrole (PPy) hydrogel. This strategy relies on a pervasive...
