Abstract—The reaction of copper(II) pivalate with aminopropyltrimethoxysilane in molar ratio Cu(II) : RNH₂
= 1 : 4 leads to the corresponding complex 1. The combined gelation of complex 1 and Si(OCH₃)₄ produces
lyogels whose structure incorporates Cu(II). The supercritical drying of the lyogels in CO₂ results in aerogels
with specific surface area up to 260 m²/g containing bivalent copper. Drying of lyogels under supercritical con-
ditions in isopropanol and methanol leads to reduction of Cu(II) into metal state.
