Abstract:
This work continues a series of our studies on the synthesis of nanostructured carbon (NSC) by
the pyrolysis of H2 + C3–C4 alkane mixtures on nickel and cobalt metal catalysts supported on chemically
diverse inorganic materials (aluminosilicates, alumina, carbon) having different textural characteristics
(mesoporous and macroporous supports) and shapes (granules, foamed materials, and honeycomb mono
liths). Here, we consider Ni catalysts supported on granular mesoporous silica (SiO2). It has been elucidated
how the yield of synthesized carbon depends on the Ni/SiO2 catalyst preparation method (homogeneous pre
cipitation or impregnation) and on the composition of the impregnating solution, including the molar ratio
of its components—nickel nitrate and urea. The morphology of catalytic NSC and Ni distribution in the sil
ica granule have been investigated using a scanning electron microscope with an EDX analyzer. Carboncon
taining composite supports (NSC/SiO2) have been employed as adsorbents for immobilizing microbial
lipase. The enzymatic activity and stability of the resulting biocatalysts have been estimated in transesterifi
cation reactions of vegetable (sunflower and linseed) oils involving methyl or ethyl acetate, esterification, and
synthesis of capric acid–isoamyl alcohol esters in nonaqueous media.
