Supercapacitive behaviour of a novel nanocomposite of 3,4,9,10-perylenetetracarboxylic acid incorporated captopril-Ag nanocluster decorated on graphene nanosheets

Abstract

We report a novel nanocomposite, G/PTCA/Capt-AgNC, which shows a drastic increase in specific capacitance in comparison to PTCA/Capt-AgNC.

Tuning the dielectric response in a nanocomposite material through nanoparticle morphology

“…In recent years, methods for synthesis of noble metal mNPs (Ag, Au, Pt) with atomic precision have been developed, and their distinctive properties have been capitalized in applications such as heterogeneous catalysis, [20][21][22][23] photocatalysis, 24 chemical and medical sensing, [25][26][27][28] and in composite materials with intriguing functionalities. [29][30][31] As methods for their synthesis have been developed, Ag nanoclusters have become a popular choice for materials' synthesis, due to their enhanced optoelectronic properties, low cost and reduced toxicity. 32,33 From a computational standpoint, Ag is a well understood metal with a lower electron count than Au and Pt, and does not require consideration of relativistic effects in calculations.…”
