Palygorskite supported manganese oxide catalysts (MnOx/PG) were prepared for lower temperature selective catalytic reduction (SCR) of NOx by NH3. Catalyst’s SCR activity was estimated at varied temper...
Ce0.8La0.2O1.9-attapulgite (Ce0.8La0.2O1.9-ATP) nanocomposite materials were synthesized by co-precipitation method. The microstructure and phase composition of the as-prepared samples were characteri...
A Ni metal form was used to carry the Ru catalyst to induce the hydrogen gas from the NaBH4 solution. Results show the Ni material was replaced by Ru material. Ru has been coating twice or more to cov...
Two grafting starch was obtained by grafting copolymerization of two synthetical vinyl monomers using HRP/H2O2 as catalyst. The structure of vinyl monomers was verified by 1H-NMR.The grafting polymer ...
The palygorskite-supported nickel (Ni/PG) catalysts were modified by loading with several additives (Fe, Mg, Mn, and Ce) by incipient wetness impregnation. The effect of the additives and their conte...
A series of heterogeneous catalysts with Cp2TiCl2 supported on palygorskite were prepared and evaluated by ethylene slurry polymerizations. The so-called direct supported catalyst, for which the pretr...
The acid-catalyzed reaction between methanol and isobutene to give methyl-t-butyl ether may be carried out using a cation-exchanged smectite as the catalyst. In 1,4-dioxan solvent at 60∑C smectites ex...
