Studies of Some Catalytic Properties of Zeolites
The use of Yetype zeolites as catalysts for the vapour phase Beckmann rearrangement of alicyclic oximes has been investigated, particularly for the conversion of cyclopentanone oxime to 2-piperidone. The rearrangements of cyclopentanone oxime and cyclohexanone oxime were studied spectroscopically, …

Preparation and Catalytic Properties of Supported Nanoscale Metal Particles
The materials were active catalysts for the decomposition of methanol to CO and H$\sb2,$ but the catalyst derived from $\rm Pt\sb2Ru\sb4(CO)\sb{18}$ displayed enhanced activity and stability. The behavior of these materials as thermal catalysts is expected to relate to their behavior as …

Green Pea Peroxidases: Their Catalytic Properties and Thermal Stabilities
A simple and effective method of identifying multiple forms of peroxidase isoenzymes was developed using analytical thin-layer isoelectric focusing (IEF) on polyacrylamide gel (PAG) plates. A total of 18 (pI's 3.5-9.1) peroxidase isoenzymes were identified from crude extracts of pea seeds; all

Catalytic properties, densification and mechanical properties of nanocrystalline yttria-zirconia-based materials
… expensive supported noble metal catalysts. Their catalytic activity could be attributed to the availability of active surface oxygen species, which facilitated the methane activation at low temperatures. Nanocrystalline 3 mol% and 8 mol% Y203-ZrO2 (3YZ and 8YZ) were successfully densified with an …
