摘要： A catalyst composition can include: a support; a ruthenium catalyst (Ru) nanoparticle; and a linker linking the Ru nanoparticle to the support, wherein the linker is stable under hydrogenolysis conditions. In one aspect, the linker can include 3-aminopropyl trimethoxysilane (APTS) or derivatives thereof, such as those with amine functionality. In another aspect, the linker can include phosphotungstic acid (PTA) or other similar solid acid agents. In another aspect, the support can be selected from alumina, carbon, silica, a zeolite, TiO2, ZrO2, or another suitable material. A specific example of a support includes zeolite, such as a NaY zeolite. The Ru nanoparticle can have a size range from about 1 nm to about 25 nm, and can be obtained by reduction of Ru salts.
