Abstract :
CoSBA-15 with different nSi/nCo ratio have been synthesized in acidic media using nonionic surfactants and characterized, for the first time, by XRD, AAS, N2 adsorption, UV–vis DRS and ESR spectroscopy. Spectroscopic data show that all cobalt atoms in CoSBA-15 are extensively in tetrahedral coordination.
