Abstract
A series of non-porous zinc-containing coordination compounds with mono- and polydentate ligands has been used to produce carbon materials with a hierarchical porous structure. Adjustment of the carbonization mode enables to increase the target product yield by an average of three times. The obtained carbons have a combination of micro- and mesopores with a pronounced maximum at 3.5 nm. The gas-sorption behavior of the obtained carbons has been studied over a wide range of temperatures and pressures. It has been established that the amount of excess adsorption for hydrogen and methane reaches 2.7 and 15 wt%, respectively. The extension of the proposed approach to the use of simple bimetallic complexes as precursors may be promising for obtaining effective catalysts based on a carbon matrix with controlled porosity and encapsulated nanoscale particles of a catalytically active metal.
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.
