Abstract
Efficient and stable catalysts are highly desired for the electrochemical conversion of hydrogen, oxygen, and water molecules, processes which are crucial for renewable energy conversion and storage technologies. Herein, we report the development of hollow nitrogenated carbon sphere (HNC) dispersed rhodium (Rh) single atoms (Rh<sub>1</sub>HNC) as an efficient catalyst for bifunctional catalysis. The Rh<sub>1</sub>HNC was achieved by anchoring Rh single atoms in the HNC matrix with an Rh-N<sub>3</sub>C<sub>1</sub> configuration, via a combination of <i>in situ</i> polymerization and carbonization approach. Benefiting from the strong metal atom-support interaction (SMASI), the Rh and C atoms can collaborate to achieve robust electrochemical performance toward both the hydrogen evolution and oxygen reduction reactions in acidic media. This work not only provides an active site with favorable SMASI for bifunctional catalysis but also brings a strategy for the design and synthesis of efficient and stable bifunctional catalysts for diverse applications.
