Synthesis of nitrogen and boron co-doped carbon (CNB) and their CO₂ capture properties: from porous to hollow granule structure

Abstract

The significant role of boron source for nitrogen doped carbon structure is demonstrated. Among variable synthesized structures, depending on their compositions of precursors <italic>via</italic> chlorination, hollow granular carbon structure is developed without any additional templates. It shows high CO₂ capture properties with excellent selectivity.
