For example, Yu et al.
[31,32] studied the effects of Ca content on Ca–Pt and Ca–Al interactions.
They found that the Ca doped Pt/c-Al2O3 exhibited a good catalytic stability for cyclohexane dehydrogenation.
The existence of Ca promoted the dispersion of Pt particles, prevented the migration
and coalescence of metal crystallites and reduced the acidit of catalysts. Yue et al.
