  • Optimization of Preparation Process of La-Ce-Palygorskite

    Response surface methodology(RSM) was applied to optimize the preparation process of La-Ce-Palygorskite catalysts for NO decomposition. The method of three-factors-three-levels central composition experiments were designed. The pH value of the chemical blending ratio of La/Ce and calcination treatment temperature of the catalysts were chosen as casual factors.

  • Preparation and Enhanced Catalytic Hydrogenation

     · A Sb/palygorskite (PAL) composite was synthesized by a facile solvothermal process and applied in catalytic hydrogenation of p-nitrophenol for the first time. It was found that the Sb nanoparticles with the sizes of 2–5 nm were well dispersed on the fiber of PAL while partial aggregated Sb nanoparticles with sizes smaller than 200 nm were also loaded on the PAL.
