Synthesis of semiconducting SWNTs by arc discharge and their enhancement of water splitting performance with TiO2 photocatalyst

Carbon nanomaterials synthesized by arc discharge hot plasma

“…In 2011, Li et al [30] developed a scalable CO 2 -assisted arc discharge method to directly synthesize SWCNTs with largely semiconducting species, in which CO 2 as a weak oxidant is considered to directly react with M-SWCNTs due to the different reactivity of S-SWCNTs and M-SWCNTs. They found that the content of S-SWCNTs all gradually increases with increasing CO 2 concentration from 0 to 25 vol %.…”

Interconnecting Carbon Nanotubes for a Sustainable Economy

“…CNTs have been used to enhance the water splitting performance of titania photocatalysts [16] but an alternative use for CNTs has been found in membranes. Nafion, a sulfonated tetrafluoroethylene based fluoropolymer-copolymer, is a membrane that has had commercial success in the fuel cell industry.…”

Cost-effective synthesis of bamboo-structure carbon nanotubes from coal for reversible lithium storage

“…The natural materials derived from biomass have been demonstrated as one kind of widely available raw materials for CNTs synthesis. [16][17][18][19] Among various precursors, coal represents the cheapest natural materials because of abundant reserves. For example, the conrmed reserve globally is over 1000 billion tonnes and China affords a production capacity of 1.4 billion tonnes yearly.…”
