Synthesis and characterisation of CoO-NiO/SBA-15 bimetallic oxide catalysts

SBA-15 material assembled with bimetallic cobalt and nickel oxides was synthesized under acidic condition. The samples were characterized by XRD, HRTEM and BEJT techniques. Results show that CoO and NiO bimetallic oxides can be homogeneously confined into the ordered pore channels of SBA-15. The loaded contents of CoO and NiO can be up to w = 0.0691 and w = 0.0837, respectively, while the ordered structure can still be well maintained. It is expected that highly dispersed CoO and NiO in the pore channels of well-ordered SBA-15 structure are very potential for advanced catalytic application.
