S. Kuba et al., An active and selective alkane isomerization catalyst: iron- and platinum-promoted tungstated zirconia, CHEM COMMUN, (4), 2001, pp. 321-322
Addition of iron sulfate to Pt-promoted tungstated zirconia increases the a
ctivity and selectivity of the catalyst for isomerization of n-pentane in t
he presence of H-2; selectivities > 98% have been observed.
