Abstract

New methods for the synthesis of metal-containing composite materials based on natural polymers (chitosan, organosolv lignin, and nanocellulose) are proposed. Metal doping was performed by introducing salts of Cu(CH3COO)2, Ni(NO3)2, and Co(NO3)2 into a suspension of the initial biopolymer mixture. The obtained chitosan–cellulose (C/C) and chitosan–lignin (C/L) composites have a sponge-like structure and they are predominantly macroporous (cavity size from 50 to 70 μm). Analysis revealed the formation of three-dimensional structures with relatively loose packing, with a surface morphology resembling foam. The thermal stability of C/L biocomposites decreased in sequence: C/L > C/L/Ni > C/L/Cu > C/L/Сo. Cobalt-containing carbon composites obtained by carbonization of C/L and C/C samples at 600°C exhibited high specific surface area and pore volume. These composites were micro/mesoporous materials with mesopore fractions of 76.5% and 64.7%, respectively. Carbonization of the nickel-containing C/C biocomposite at 600 °C yielded a carbon composite with a predominantly microporous structure. The influence of the introduced metal nature, organic matrix composition, and carbonization temperature on the morphology and microstructure of the carbon composites was studied by SEM, XRD, and spectral chemical analysis methods. Samples carbonized at 400 to 600 °C consisted of three-dimensional structures of randomly linked film fragments with large cells. The distribution of the metal (Co, Ni, Cu) over the carbon support surface was found to be uniform.
