Thermal Puffing Promoting the Synthesis of N-Doped Hierarchical Porous Carbon-CoO _x Composites for Alkaline Water Reduction.

ABSTRACT: N-doped porous carbon-based catalysts hold great promise for hydrogen evolution reaction (HER) due to their plentiful cavity construction, high specific surface area, and flexible metal assemblies. Nevertheless, the cumbersome synthetic process and the use of highly corrosive chemicals greatly increase the production costs and pollutions. Herein, we report a facile and eco-friendly thermal puffing strategy, which imitates the popcorn forming process, for the fabrication of N-doped hierarchical porous carbon-CoO _x catalysts. The results indicate that the well-developed porosity and high specific surface area (696 m² g^-1) of CoO _x -NC-1.0 are achieved during the thermal expansion. Impressively, the as-prepared CoO _x
