Ei. Berdanova et al., PREPARATION AND PROPERTIES OF HIGHLY DISPERSED COPPER-OXIDE IN A ZEOLITE MATRIX, Russian chemical bulletin, 46(10), 1997, pp. 1667-1669
Highly dispersed CuO clusters inserted into a zeolite matrix were prep
ared by oxidative degradation of the (mu(4)-O)L4Cu4Cl6 tetranuclear co
mplex (L is N,N-diethylnicotinamide) preadsorbed on a dehydrated NaX z
eolite from a solution in anhydrous dichloromethane. The catalytic act
ivity of the CuO/NaX catalyst thus obtained in the oxidation of CO is
an order of magnitude higher than that of massive CuO.
