A Solid Dual-Ions-Transformation Route to S,N Co-Doped Carbon Nanotubes as Highly Efficient Metal-Free Catalysts for Organic Reactions

Contents A green and cost-effective method, named the solid dual-ions-transformation reaction, is reported to achieve the goal of successfully doping S and N into hollow carbon nanotubes. No harmful raw material is needed during the whole synthesis. Importantly, in the catalytic test of chemical reduction of p-nitrophenol by NaBH4, the as-obtained S, N co-doped hollow carbon nanotubes exhibit ultrahigh catalytic performances.
