Zeolite-templated carbon-supported Ru-based catalysts for efficient alkaline hydrogen evolution reaction

Herein, a series of Ru/ZTCs samples were prepared using LaY zeolite-templated carbon as a support. Characterizations showed that the unique structure of the ZTCs and the chemical state of Ru facilitated superior HER performance compared to other carbon-supported samples. This work offers a new strategy for designing excellent electrocatalysts. Zeolite-templated carbon (ZTC) has a uniform porous structure that confines the Ru clusters, and also has a high graphitization, which enables the Ru/ZTCs catalysts to exhibit excellent activity and stability in HER process.
