摘要: Abstract The well-ordered polyhydroxyacetato-Cr3+ species intercalated molybdenum trioxide by the reaction of an aqueous solution Cr(OAc)3 with a dispersion layered sodium bronze ([Na(H2O)5]0.25MoO3) was prepared. X-ray fluoroscopy (XRF), TGA and near/UV–VIS spectra showed that intercalates may mainly be trimers tetramers. first chromia-pillared interlayer distance 10.9 A then obtained after calcined at 350 °C in flow mixed nitrogen oxygen (4% O2, v/v). porous material has surface area 82.4 m2 g−1, ca. 60% pores having rp
