Abstract: A method of producing an organoselenium-based nanocomposite includes acid-treating a mixture containing multi-walled carbon nanotubes (MWCNT) and palm waste with phosphoric acid to form an acid-treated mixture; carbonizing the acid-treated mixture to form a MWCNT/biochar; mixing the MWCNT-biochar with TiO2 nanoparticles to form a TiO2-MWCNT/biochar; chlorinating acyl groups present on the TiO2-MWCNT/biochar to form a chlorinated TiO2-MWCNT/biochar; reacting the chlorinated TiO2-MWCNT/biochar with an organoselenium compound to form a Se—TiO2-MWCNT/biochar.

Abstract: The present invention relates to a method for preparing carbon nanotubes, the method including: preparing a support including AlO(OH) by primary heat treatment of Al(OH)3; preparing an active carrier by supporting a mixture including a main catalyst precursor and a cocatalyst precursor on the support; drying the active carrier through multi-stage drying including vacuum drying; preparing a supported catalyst by secondary heat treatment of the dried active support; and preparing carbon nanotubes in the presence of the supported catalyst, and the carbon nanotubes prepared by the method as described above can remarkably improve conductivity.

Abstract: Methods for recycling thermoset polymers, particularly by changing them into dynamic networks with the use of an appropriate catalyst solution which transforms the thermoset polymer into a vitrimer-like composition. The methods include the step of swelling a crosslinked thermoset polymer in a solution including a catalyst, whereby the catalyst diffuses into the thermoset polymer, in particular into the thermoset network. Upon removal of the liquid portion of the solution, such as solvent, the catalyst facilitates the occurrence of exchange reactions at elevated temperatures, rendering the system a dynamic network. The vitrimerized composition having the thermoset polymer and catalyst is recyclable and processable and thus suitable for many end uses.
