Upcycling spent petroleum cracking catalyst: pulsed laser deposition of single-wall carbon nanotubes and silica nanowires

Abstract

From waste to single-wall carbon nanotubes and silica nanowires: the first high-tech outlet for FC3R.

Scaling up single-wall carbon nanotube laser annealing: effect on electrical resistance and hydrogen adsorption

“…Furthermore, (3) the application-relevant mm scale brings this promising technique closer to industry with sights on higher quality tubes, cheaper synthesis and recovery of unavoidable processing-related damage. This can be extended to unachievable tube qualities, due to alternative complex organic precursors, 48 bringing such CNTs up to industry standards and closer to sustainability. A nal corollary of damage recovery is (4) the possible rejuvenation of electrical cycling or wear-related damage to CNT materials, to extend their duty life.…”
