文摘

Mg addition decreases the weak Brønsted acidity of alumina. Decrease of Brønsted acidity affects the electronic properties of the MoS2 phase. Hydrogenation activity of MoS2 is balanced by electronic properties and Mg element. O2− sites on the support may be beneficial for hydrogenation activity by spillover effects.
