Highly active quinone site-enriched carbon nanotube composites for efficient electrocatalytic hydrogen peroxide generation

Abstract

We propose a facile and scalable in situ polymerization strategy to selectively introduce the active quinone-based components across the carbon nanotube (CNT) surface. It can be observed that the optimized...

Template free preparation of graphene tubes from polyimide catalyzed by calcium carbonate

“…GTs combine the physical and chemical properties of graphene and the hollow structure of carbon nanotubes, making them potentially useful in fields such as field emission cathode materials, new energy batteries, sensors, supercapacitors, catalysts, and adsorption materials. 3–10 The diameter of typical carbon nanotubes is about 1–100 nm, 11–14 while GTs usually have larger diameters, up to the micrometer level. Q Li 15,16 suggest that large-sized GTs can provide larger platforms than carbon nanotubes, serving as a new type of carrier for oxygen reduction catalyst development, which can better deposit metal nanoparticles, and highly graphitized GTs can interact strongly with catalyst nanoparticles to prevent their aggregation.…”
