Gas-template directed in situ synthesis of highly nitrogen-doped carbon nanotubes with superior sulfur compatibility and enhanced functionalities

Abstract

Herein, we develop a low temperature gas template route for in-situ growth of highly nitrogen-doped (5.68wt.%), multi-walled carbon nanotubes (N-MWCNTs). The obtained N-MWCNTs exhibit superior sulfur compatibility in hydrogen sulfide...

Advances in Resources Recovery of H2S: A Review of Desulfurization Processes and Catalysts

“…Carbon nanotubes (CNT) have recently received intense attention in catalysis. , With rich surface chemistry (heteroatoms and structural defects), diverse structures (number of graphene layers and internal/external diameter), and lack of microporosity, CNT shows better potential than microporous AC in the desulfurization reaction . In addition, the tubular morphology of CNT ensures the peculiar reactivity of feed reagents for various reactions.…”

Highly Efficient Conversion of Lignin into Diethyl Maleate Catalyzed by Molybdenum-Based Hybrid Catalysts

“…Therefore, there is a pressing need for the transformation of lignin using low-cost heterogeneous catalysts. Nitrogen-doped carbon-loaded metal materials have garnered significant interest due to their high concentration of oxygen-containing groups, excellent dispersibility, easy modification reactivity, and favorable properties. − Moreover, the addition of N dopants can improve the catalytic activity of nitrogen-doped carbon-supported metal catalysts by enhancing the conductivity between metal sites and carbon substrates …”
