Probing non-Faradaic process during elastic deformation in a single sphere of extremely soft mesoporous carbon
Mesoporous carbon materials, known as graphene mesosponges (GMS), exhibit remarkable flexibility. These materials are expected to advance the field of physical chemistry through the investigation of phenomena induced by significant deformation of mesopores when mechanical forces are applied. In this work, GMS has been synthesized in the form of spherical microparticles, namely micro-spherical GMS (ms-GMS). The remarkable flexibility of ms-GMS has been validated through mercury intrusion tests, and also by methanol adsorption measurements with and without the application of mechanical force. Moreover, we successfully capture live footage of the elastic deformation of a single ms-GMS particle, enabling the determination of ‘the Poisson's ratio. Furthermore, we are attempting to observe the non-Faradaic process that occurs within a single sphere during mechanical deformation, utilizing scanning electrochemical cell microscopy (SECCM). The results showed a noticeable decline in capacitive rate performance when the pore size decreased from 7 to 2 nm. This approach effectively minimizes interference from other structural variations that typically arise during carbon synthesis and electrode fabrication, offering a new avenue for elucidating the specific influence of pore size in such materials.
期刊介绍:
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
