rationalized this from the increase (50 nm from 35 nm) in Cu(0) metal particles size
by the TEM analysis of the spent catalyst.
Aytam research group reported ex situ-reduced Ni(0)/Al 2 O 3 -TiO 2 catalyst,
derived from Ni-Al-Ti LDH precursor [69]. The mixed metal catalyst has high catalytic activity for vapor-phase hydrocyclization of LA to Gvl as compared with
Ni(0)/TiO 2 and Ni(0)/Al 2 O 3 (Table 1, entries 24–26). The high concentration of
Fig. 2 Powder XRD pattern for NiAl-LDH (catalyst precursor) and Ni(0)@boehmite (catalyst
obtained after the reaction). The XRD pattern for Ni(0)@boehmite matched well with nickel
(JCPDS Card No: 004-0850; stick pattern included) and boehmite (JCPDS Card No: 01-074-290)
