Best insight from top research papers
The isolated metalporphyrin capacitance value can vary based on the specific metal atom decoration. Research suggests that transition metal atom decoration on graphene can impact the quantum capacitance, with varying effects depending on the metal type. For instance, Sc and Fe decoration can lead to increased capacitance values of 177μF/cm2 and 220μF/cm2, respectively, compared to pristine graphene . Additionally, the capacitance of a multifunctional sensor utilizing a copper(II) porphyrin compound was found to increase significantly under different conditions, such as a 4.7 times increase under illumination and a 9.5 times increase with rising humidity levels . These studies highlight the influence of metalporphyrin decoration and environmental factors on capacitance values.

How large is the capacitance of EDLC compared to conventional dieelectric capacitors?5 answersThe capacitance of electric double-layer capacitors (EDLCs) is significantly larger compared to conventional dielectric capacitors. EDLCs utilize the electric double layer formed at the interface between the electrode and the electrolyte to store charge, resulting in a huge capacitance due to the extremely small distance between the electrode surface and the double layer. In particular, the use of two-dimensional electrically conductive metal-organic frameworks (MOFs) as electrodes in EDLCs has shown promising results, with specific capacitances ranging from 110-114 F g-1. Additionally, the use of carbon-coated gold electrodes with ionogel electrolyte in on-chip EDLCs has achieved a ten-fold increase in capacitance compared to bare gold electrodes. Furthermore, the use of zeolite templated carbon (ZTC) as an electrode material has demonstrated large specific capacitance values of over 240 F g-1. These findings highlight the superior capacitance performance of EDLCs compared to conventional dielectric capacitors.
