Perovskite-type materials LaCoO 3 , LaCo 1− x Cu x O 3− δ , and Cu 2 O/LaCoO 3 were synthesized by the mechano-synthesis process known as reactive grinding. Their characterization was performed by BET, X-ray diffraction, SEM, O 2 -TPD, and H 2 -

The specific surface area of ground perovskites is strongly dependent on the synthesis and pretreatment conditions. Calcining the ground LaCo1-xCuxO3-? perovskites at 5000C causes a decrease of their specific surface, but the further reductive pretre

Synthesis and catalytic properties of sulfonic acid-functionalized periodic mesoporous organosilicas
Two types of sulfonic acid functionalized mesoporous materials ASMES (arene sulfonic acid ethane-silica) and ASSBA-15 (arene sulfonic acid SBA-15), were synthesized in one step and characterized using XRD, BET, TEM and 13C MAS NMR. Liquid phase aceta
