| Abstract: | Mesoporous SBA-15(Stanta Barbara amorphous) silica particles were prepared in strong acidic conditions(1.6 mol/L HCl) with triblock copolymer Pluronic P123(poly(ethyleneglycol)-block-poly(propyleneglycol)-block-poly(ethyleneglycol)) as templating agent.Characterization result shows it has highly ordered hexagonal mesoporous running along the same direction,extremely narrow pore size distribution(5.8 nm) and high surface areas(799 m2/g).The SBA-15 particles were successfully applied for the normal phase chro... |
