Adsorption and photocatalytic degradation of bisphenol A by low-cost carbon nanotubes synthesized using fallen leaves of poplar

Carbon nanotubes from renewable feedstocks: A move toward sustainable nanofabrication

“…In addition to that, a variety of metal nanoparticles and metal‐nanoparticle functionalized materials have been produced using plant‐extract mediated bioreduction processes . Carbon nanomaterials (such as spheres, fibers, carbon dots, graphenes, and carbon nanotubes) synthesized from renewable resources has also attracted many researchers around the globe …”

“…Chemical vapor deposition and spray pyrolysis have been extensively used for the processing of liquid feedstocks. Using solid precursors such as leaf, grass, and other biomasses, thermal pyrolysis has been employed repeatedly for the condensation of biomass as well as the formation of nanotube structures . By manipulating the type of catalysts one can easily achieve the desired structure of carbon nanotubes by employing renewable precursors.…”

“…This leads to the retention of tubular structures even after repeated carbonization process at higher temperatures . Qu et al . demonstrated the synthesis of CNTs from the fallen leaves of poplar by employing a simple thermal decomposition process under ambient air conditions.…”

“…[73][74][75] Carbon nanomaterials (such as spheres, fibers, carbon dots, graphenes, and carbon nanotubes) synthesized from renewable resources has also attracted many researchers around the globe. [76][77][78][79][80][81][82] Renewable Resources for Carbonaceous Materials Finite petroleum resources, unstable crude oil prices, ever increasing global concern on environmental challenges (CO 2 emissions, and climate change), and emerging demand for sustainable materials requires a change in the fabrication of carbon nanomaterials by using renewable resource based precursor materials with a smaller carbon footprint than traditional petroleum resource based materials. 72,83,84 Many types of carbon nanomaterials such as tubes, particles, fibers, sheets, dots, onions, and graphenes have been synthesized with renewable precursors.…”

“…Using solid precursors such as leaf, grass, and REVIEW WILEYONLINELIBRARY.COM/APP other biomasses, thermal pyrolysis has been employed repeatedly for the condensation of biomass as well as the formation of nanotube structures. 81,101 By manipulating the type of catalysts one can easily achieve the desired structure of carbon nanotubes by employing renewable precursors. The following section summarizes the recent developments in the production of CNTs from different biosourced feedstocks.…”
