O, N co-doped porous activated carbon from polyvinyl chloride for super capacitors and solar cells application

Porous-activated carbons (PAC) show a lot of applications in various fields due to their large surface area and appropriate pore volume, along with decent thermal, chemical, and mechanical stability. Because of these characteristics, PACs are the best choice as an electrode material in supercapacitors (SCs). Due to the utility of PACs, this work reports the transformation of polyvinyl chloride (PVC) into PAC with a surface area of 162.40 m 2 /g. The synthesized PAC exhibits a maximum specific capacitance (CSP) of 40 F/g at five mV/s in 1-ethyl-3- methylimidazolium thiocyanate ionic liquid (EMIM SCN-IL) electrolyte. Also, no degradation was recorded in the initial C sp of the fabricated SC, even after 9000 cycles at room temperature. Additionally, using the same…
