Carbon-doped boron nitride nanosheets as an efficient metal-free catalyst for the selective oxidation of H2S

Abstract

We report the first use of carbon-doped boron nitride (BCN) for H₂S-selective catalytic oxidation. The obtained carbon-doped BN with an ultrathin layer structure exhibits outstanding H₂S elimination and high S yield. In particular, BN doped carbon nanosheets display better catalytic performance than traditional catalysts, such as iron- and carbon-based catalysts. The findings of the present work shed a new light on metal-free catalysts for efficient catalytic removal of toxic H₂S.
