Metals (Fe, Ti, Zr) were doped into mesoporous MCM-41 by a one-step method using cetyltriethylammonium bromide (CTAB) micelles with micellar solubilized metallocenes as templates. X- ray diffraction (XRD) and N2 adsorption-desorption isotherms show that after metallocene doping, M- MCM-41(T) materials still preserved the ordered hexagonal structure and high BET surface area. Inductively coupled plasma atomic emission spectrometry (ICP-AES) indicated that the mass fractions of the metals in the corresponding samples are: 1.71% Fe in Fe-MCM-41(400), 0.95% Ti in Ti-MCM-41(550) and 0.81% Zr in Zr-MCM-41(550). All the M-MCM-41(T) materials showed a particular high catalysis effect for the esterification of acetic acid and n-butanol. The TOF of Fe-MCM-41(400) and Zr-MCM-41(550) were 55643 g·h-1·g-1 and 125320 g·h-1·g-1, respectively, which is much higher than that of the corresponding pure metallocenes.
