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

We report the first use of carbon-doped boron nitride (BCN) for H 2 S-selective catalytic oxidation. The obtained carbon-doped BN with an ultrathin layer structure exhibits outstanding H 2 S elimination and high S yield. In particular, BN doped carbon nanosheets display better catalytic performance...

Description
Summary:We report the first use of carbon-doped boron nitride (BCN) for H 2 S-selective catalytic oxidation. The obtained carbon-doped BN with an ultrathin layer structure exhibits outstanding H 2 S 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 H 2 S. The as-designed carbon-doped BN with an ultrathin layer structure shows outstanding H 2 S elimination and high S yield.
