摘要：
Supported Co3O4 catalysts were prepared via the calcination of Co-containing hydrogarnet, (Ca3-xCox)Al2(SiO4)3- y(OH)4y, at 400 °C. Such precursors with various extents of substitution were synthesized from the hydrothermal reaction of a stoichiometric mixture of calcium oxide, amorphous silica, alumina sol, and cobalt hydroxide at 200 °C. It was found that the catalyst consisted of Co3O4, CaO, and mayenite and exhibited a high activity for the combustion of propylene, benzene, and toluene at temperatures below 300 °C.
