The catalytic properties of manganese oxide octahedral molecular sieve materials (OMS-2) with different metal cation dopants ( M : Cu 2+ , Zn 2+ , Ni 2+ , Co 2+ , Al 2+ , or Mg 2+ ) were investigated for the reaction of 2-propanol decomposition. Comp

Both the abundance of alkanes and their extremely low activity have greatly interested several researchers. In this paper, different metal substituted 3×3 octahedral molecular sieves (OMS-1) materials were used to catalyze the functionalization of c

n -Butene was isomerized to isobutene over fresh and used ferrierite catalysts. Activity and selectivity for skeletal isomerization and biproduct formation were measured and changes following extended use were related to changes in ferrierite′s alu

Octahedral molecular sieves (OMS) having the todorokite (OMS-1) and hollandite (OMS-2) structures were used to modify carbon paste electrodes, and their cyclic voltammograms were recorded. The presence of Mn[sup 2+] in OMS-1 makes it electroactive; O
