A series of Cr-containing MCM-41 molecular sieves crystallized at room temperature with a hexagonal and well-ordered structure were synthesized. XRD, FT-IR and
Selective catalytic reduction (SCR) of nitric oxide with propane in excess oxygen was investigated on Ni-ZrO2 (NZ) and sulfated Ni-ZrO2 (SNZ), prepared by copre
A Ru-La/ZrO2 catalyst was prepared by the precipitation method, in which Ru was an active component, La was a promoter and ZrO2 was a dispersant. Comparing with
