Quan, Cui published the artcileSynthesis of carbon nanotubes and porous carbons from printed circuit board waste pyrolysis oil, HPLC of Formula: 74896-66-5, the main research area is synthesis porous carbon printed circuit board waste pyrolysis oil; carbon nanotube synthesis printed circuit board waste pyrolysis oil.
The possibility and feasibility of using pyrolysis oil from printed circuit board (PCB) waste as a precursor for advanced carbonaceous materials is presented. The PCB waste was 1st pyrolyzed in a laboratory scale fixed bed reactor at 600° to prepare pyrolysis oil. The anal. of pyrolysis oil by gas chromatog.-mass spectroscopy indicated that it contained a very high proportion of phenol and phenol derivatives It was then polymerized in formaldehyde solution to synthesize pyrolysis oil-based resin which was used as a precursor to prepare C nanotubes (CNTs) and porous carbons. SEM and transmission microscopy investigation showed that the resulting CNTs had hollow cores with outer diameter of ∼338 nm and wall thickness of ∼86 nm and most of them were filled with metal nanoparticles or nanorods. X-ray diffraction reveals that CNTs have an amorphous structure. N adsorption isotherm anal. indicated the prepared porous carbons had a Brunauer-Emmett-Teller surface area of 1214 m2/g. The mechanism of the formation of the CNTs and porous carbons is discussed.
