摘要: Abstract The development of active and stable metal-based catalysts are highly desired in chemical transformation. As is known, the catalytic activity durability supported catalyst strongly dependent on morphology supporting material size distribution metal nanoparticles (NPs). We report fabrication a high-performance nitrogen-doped carbon tubes@Pd (NCT@Pd) catalyst, which well-dispersed ultrafine Pd NPs were deposited onto N-doped microtubular support. Due to synergy effect between permeable mesoporous NCT shell anchored NPs, resultant NCT@Pd tubular shows remarkably high toward reduction 4-nitrophenol with turnover frequency (TOF) 29.5 min −1 , even when loading amount as low 0.324 wt%. Furthermore, can also be applied for Suzuki coupling reaction TOF up 44.0 .
