•Pt/Sn/M/γ-Al2O3 catalysts with third metal (M = Zn, In, Y, Bi, and Ga) were prepared.•Direct dehydrogenation of n-butane to n-butene and 1,3-butadiene was conducted.•Catalytic performance increased with increasing metal–support interaction.•Catalytic performance increased with increasing Pt surface area.
A series of Pt/Sn/M/γ-Al2O3 catalysts with different third metal (M = Zn, In, Y, Bi, and Ga) were prepared by a sequential impregnation method for use in the direct dehydrogenation of n-butane to n-butene and 1,3-butadiene. In the direct dehydrogenation of n-butane, Pt/Sn/Zn/γ-Al2O3 catalyst showed the best catalytic performance. Catalytic performance decreased in the order of Pt/Sn/Zn/γ-Al2O3 > Pt/Sn/In/γ-Al2O3 > Pt/Sn/γ-Al2O3 > Pt/Sn/Y/γ-Al2O3 > Pt/Sn/Bi/γ-Al2O3 > Pt/Sn/Ga/γ-Al2O3. The catalytic performance increased with increasing metal–support interaction and Pt surface area of the catalyst.
