СИНТЕЗ СеО2-МоО3 КАТАЛІЗАТОРІВ СЕЛЕКТИВНОГО ОКИСНЕННЯ ЕТАНОЛУ НЕТРАДИЦІЙНИМИ МЕТОДАМИ
The influence of mechanochemical (MChT) and ultrasonic (UST) treatment on physic-chemical properties of СеО2-МоО3=1:1 composition was studied. The prepared samples were characterized by methods of XRD, ESR, N2 adsorption, SEM and TEM methods. The catalytic properties of obtained samples were studied...
