摘要: Abstract Anodic alumina oxide (AAO) supports with different pore sizes and depths were controllable prepared by a two-step low-potential anodizing process. The AAO θ-ring shape utilized to prepare supported Pd catalysts impregnation method for the first time. catalytic performance of Pd/AAO@Al investigated in hydrogenation 2-ethylanthraquinone (eAQ) 2-ethylanthrahydroquinone, key step anthraquinone process manufacture hydrogen peroxide. Compared on spherical Al 2 O 3 catalyst, showed much higher activity preferable selectivity due highly ordered array cylindrical shaped pores, short diffusion distance confinement effect supports. Furthermore, size depth towards eAQ has also been studied. nanoparticles support 24.5 nm 18 μm exhibited best eAQ.
