“…These results suggest that adding carbon quantum dots to the NiS base improves the charge transfer process and thus enhances the performance of the supercapacitor (Sahoo et al 2018). Oskueyan et al (2020) used carrot juice as a biomass carbon source and prepared carbon quantum dots by hydrothermal method, followed by polyaniline-carbon quantum dots by in situ polymerization. The electrochemical properties of polyaniline with different carbon dot contents were investigated and polyaniline nanocomposites with a carbon dot content of 10 wt% were selected to be mixed with polypyrrole-graphene to prepare high-potential window supercapacitors.…”

“…This work provides a new class of bifunctional nanocomposites for supercapacitors. In short, the study not only utilizes natural materials to produce supercapacitor electrodes with low material cost but also combines conducting polymers with biomass carbon for supercapacitor applications, demonstrating the potential application of biomass waste carbon quantum dots in energy storage devices (Oskueyan et al 2020).…”

In the context of the circular economy and decreasing earth resources, waste should be converted into value-added materials such as carbon quantum dots, which are fluorescent nanomaterials with promising applications in sensing, biological imaging, energy storage, and photocatalysis. Here, we review carbon quantum dots with focus on their synthesis from biomass, factors controlling their performance, properties, and applications in energy, medicine, and environmental science. Applications include energy storage in batteries and supercapacitors, renewable energy, pollutant sensing and degradation, drug delivery, biosensing, and bioimaging.

“…Utilizing biomass as a renewable carbon source represents an attractive means to reduce raw material costs in preparing a product. For instance, the utilization of carrot juice as the carbon source in preparing carbon dots has been reported by Oskueyan et al 75 The carbon dots from carrot juice were mixed with PANI, PPy, and Gn to prepare the composite electrodes. Although biomass-derived material can reduce the raw material cost, the resulting SC electrodes exhibited relatively low stability; wherein, the retention stability is reduced to 62% after only 1,000 cycles.…”

The high demand for efficient energy devices leads to the rapid development of energy storage systems with excellent electrochemical properties, such as long life cycles, high cycling stability, and high power density. SC is postulated as a potential candidate to fulfill this demand. The combination of graphene and polyaniline can create SC electrodes with excellent electrical conductivity, high specific surface area, and high capacitance. The graphene/polyaniline hybrid electrodes represent an attractive means to overcome the major drawbacks of graphene or polyaniline non-hybrid (single) electrode materials. In this review article, the trend in the development of various graphene/polyaniline hybrid electrodes is summarized, which includes the zero-dimension graphene-quantum-dots/polyaniline hybrid, one-dimension graphene/polyaniline hybrid, two-dimension graphene/polyaniline hybrid, and three-dimension hydrogel-shaped graphene/polyaniline hybrid. Several strategies and approaches to enhance the capacitance value and cycling stability of graphene/polyaniline hybrid electrodes are discussed in this review article, such as the addition of transition metal oxides and metal-organic frameworks, and modification of graphene into functionalized-graphene. The performance of the electrodes prepared from the combination of graphene with other conducting polymers (i.e., polypyrrole, polythiophene, and polythiophene-derivatives) is also discussed.
