Supercapacitive Behavior of Two Glucose-Derived Microporous Carbons: Direct Pyrolysis versus Hydrothermal Carbonization

Different Supercapacitive Behavior of Two Glucose-derived Microporous Carbons: Direct Pyrolysis versus Hydrothermal Carbonization

This work compares for the first time the physical and chemical characteristics of activated carbons produced from glucose and hydrothermally carbonized glucose, as well as their performance as electrodes in supercapacitors in aqueous electrolyte (H2SO4). Both KOH-activated carbons exhibit similar textural properties, with BET surface areas of ~ 1400-1500 m/g and a pore volume of ~ 0.70 cm/g, t...

Hydrothermal synthesis of microalgae-derived microporous carbons for electrochemical capacitors

Hydrothermal carbonization of municipal waste streams.

Hydrothermal carbonization (HTC) is a novel thermal conversion process that can be used to convert municipal waste streams into sterilized, value-added hydrochar. HTC has been mostly applied and studied on a limited number of feedstocks, ranging from pure substances to slightly more complex biomass such as wood, with an emphasis on nanostructure generation. There has been little work exploring ...

Nanoporous carbons through direct carbonization of a zeolitic imidazolate framework for supercapacitor electrodes.

Nanoporous carbons with high surface area are achieved through direct carbonization of a commercially available zeolitic imidazolate framework (ZIF-8) without any additional carbon sources. The resultant nanoporous carbons exhibit high electrochemical capacitances in an acidic aqueous electrolyte.
