“…The precursor is a biorenewable resource, areca nut kernel, and CNSs are produced by a catalyst‐free, one‐pot pyrolysis technique, ensuring cost‐effective carbon source and synthetic procedure. This work is a continuation of our previous studies on waste‐to‐wealth approach . The bio‐derived CNSs are directly used as catalytic support to Pd without any further activation, unlike the activated carbon materials that are currently in use .…”

A new heterogeneous catalyst was synthesized by immobilizing Pd on areca nut kernel‐derived carbon nanospheres (CNSs). The CNSs, without any further activation processes, accommodated 3% of Pd on their surface. The new Pd/CNS material was used for the reduction of nitroarenes and Suzuki–Miyaura coupling of bromoarenes with aryl boronic acids. The reactions were conducted under microwave irradiation at 160 °C using 12 mol% of Pd/CNS (0.36% actual Pd content). The reduction of nitroarenes into their respective amino compounds was achieved in 10–20 min (conversion up to 100%); by contrast, the Suzuki–Miyaura reactions yielded up to 98% at 150 °C with 10 mol% of Pd/CNS catalyst. The products were identified using gas chromatography and nuclear magnetic resonance spectroscopy. The catalyst was isolated from reaction mixture and reused without any significant loss in the activity. Thus, the present work introduces one‐pot‐derived porous CNSs as efficient catalytic support to Pd, establishing an alternative to existing Pd/C in terms of cost and efficiency.

Supercapacitors are perfect energy storage devices; they can be charged almost instantly and release energy over a long time. They can be charged multiple times with minimal degradation in performance. Supercapacitor performance is determined by the composition of the electrode and advanced configurations. In this review, we compare the performance of different electrode materials which are obtained from biowaste based precursors. Our main interest here in this review is to study the supercapacitor properties using carbon based spherical natured particles well known as carbon nanospheres. Carbon based electrodes, particularly bio-waste activated carbon nanospheres, have gained interest due to their excellent energy storage ability. In this paper, Activated Carbon Nanospheres derived from several bio-waste materials are reviewed on the basis of their cyclic voltammogram, specific capacitance, surface area, electrolyte used and fabrication process. area of 645 m 2 g -1 , 94% retention was found in the capacitance after 1000 cycles. 95

“…Particularly, different synthetic routes were adopted to get the finest carbon nanoparticles (CNPs) having uniform size and shape distribution with appreciable surface area . Amongst, the pyrolysis method is relatively better than wet‐chemical process due to its high yield and reproducibility . Using pyrolytic process several attempts were made to convert malignant environmental waste into degradable/benign substances.…”

Nanoparticles of carbon derivatized from pyrolysis of biowaste oil palm leaves were processed as electrochemical transducer material at the interface of glassy carbon electrode. This modified electrode exhibits convincing electron‐transfer property for voltammetric and chronoamperometric quantification of clinically important phytochemical, butein, without the use of external redox mediator and enzyme. A reversible two‐electron transfer redox property observed from butein is distinct at the electrode interface and the current density is found to be superior in phosphate buffered saline electrolyte at pH 7.0. Carbon nanoparticles interfaced electrode system displayed a good stability and sensitivity for butein with a detection limit of 7.6 μM and a dynamic detection concentration ranging from 10 to 100 μM. This bio‐waste translated carbon nanoparticle represent a promising electrode material for various flavonoids detection useful for biological studies.
