ABSTRACT

A new supermicroporous chromium oxophenylphosphate (CPP-1) has been synthesized using phenylphosphonic acid (PPA) as phosphorus source under hydrothermal condition at 443 K without using any structure-directing agent (SDA). The material has been characterized by powder XRD, FE SEM-EDS, TEM, TG-DTA, N2 sorption, XPS, FT IR, UV-Vis spectroscopic techniques and CHN chemical analysis. CPP-1 showed specific surface area of 313 m2g-1 with extra large supermicropores having dimension of ca. 1.4 nm. TEM result suggested lamellar type pore-wall structure for this material. It exhibited good catalytic property in partial oxidation of olefins in presence of tert-butylhydroperoxide (TBHP) as oxidant.
