“…Over 92% of original capacitance was retainable beyond 1000 cycles. [83] Wen et al used a mixture of five-component plastic waste containing PP, PVC, PE, PET, and PS from different sources to develop carbon nanosheets (CNSs) with 2198 m 2 g −1 specific area. The material exhibited a maximum specific capacitance of 207 F g −1 at 0.2 A g −1 with 6 m KOH and maintained a capacitance retention of 72.5% at 10 A g −1 .…”

Supercapacitors store electrical energy on the basis of electrostatic attraction between opposite charges as a result of the formation of an electric double layer (EDL) at the electrolyte/electrode interface. Carbon-derived materials are commonly used to fabricate supercapacitor electrodes owing to their high electrical conductivity, high capacitance, excellent porosity, good electrochemical stability, and large specific surface area. [131-136] Predominantly, these materials include carbon nanotubes (CNTs), graphene, carbon spheres, hollow carbon spheres, carbon nanoparticles (CNPs), etc. [62,137-145] Nevertheless, they fail to demonstrate the desirable performance in practical applications after a certain threshold owing to their short durability and low energy density. Although, metal-organic frameworks (MOFs) have proven to be better electrode candidates in certain aspects, [142,143,146-148] however, these materials incur high cost, low yield of porous carbon, high consumption of metallic nitrate, [62] and hence higher waste generation. Due to the rising concerns of waste production and its management and hence the need for sustainable and cheap resources, reusing and/or converting waste from various sources such as industrial, agricultural, food, and spent electronic devices efficiently into usable carbon has attracted much interest since recently.

At present, plastic waste accumulation has been observed as one of the most alarming environmental challenges, affecting all forms of life, economy, and natural ecosystems, worldwide. The overproduction of plastic materials is mainly due to human population explosion as well as extraordinary proliferation in the global economy accompanied by global productivity. Under this threat, the development of benign and green alternative solutions instead of traditional disposal methods such as conversion of plastic waste materials into cherished carbonaceous nanomaterials such as carbon nanotubes (CNTs), carbon quantum dots (CQDs), graphene, activated carbon, and porous carbon is of utmost importance. This critical review thoroughly summarizes the different types of daily used plastics, their types, properties, ways of accumulation and their effect on the environment and human health, treatment of waste materials, conversion of waste materials into carbon-based compounds through different synthetic schemes, and their utilization in energy storage devices particularly in supercapacitors, as well as future perspectives. The main purpose of this review is to help the targeted audience to design their futuristic study in this desired field by providing information about the work done in the past few years.

During thermal treatment of polyvinyl chloride (PVC) at 250-310℃, dechlorination reaction occurs and carbon atoms change from sp 3 hybridization to sp 2 hybridization. As the temperature rises, these carbon atoms of sp 2 hybridization are further assembled to form aromatic carbon. The product, carbon material, often has a certain degree of graphitization and high conductivity, thus being an excellent precursor for capacitor electrodes. In the absence of activators, PVC was converted to hierarchical porous carbon material (HPC) with a high yield and a specific capacitance of 226 F/g (1 A/g) successfully by using nano-ZnO as a template and catalyst. By comparing the mixing method of ZnO and PVC, and whether to remove ZnCl 2 before high-temperature carbonization, it is found that ZnO reduced the graphitization degree of the carbon materials, meanwhile introduced oxygen functional groups on the surface of the material, while ZnCl 2 had an opposite effect. The pore structure and graphitization properties of HPC can be further improved to enhance the capacitance performance by controlling the type and size of catalysts. This study provides a reference for the design of PVC-based HPC.
