Mesoporous Carbon Materials as Electrodes for Electrochemical Supercapacitors

In this paper, we report the synthesis and characterization of mesoporous carbons, which were obtained using SBA-15 silica as the template material and sucrose as the carbon source. The prepared silica template and mesoporous carbons were characterized by nitrogen adsorption-desorption, low angle X-ray diffraction (XRD) and transmission electron microscopy (TEM). Synthesized carbons were used t...

Organic-Inorganic Hybrid Materials for Supercapacitors

We present the design and development of hybrid organic – inorganic materials with improved electrochemical performance to be used in energy storage applications (e.g. supercapacitors). The systematic study carried out shows various carbon–based materials (e.g. activated carbons, graphene based materials) working as active substrates where the anchoring of inorganic species takes place (i.e. po...
