中文摘要	Mesoporous bioactive glass (MBG) of CaO–SiO2–P2O5 was synthesized using nonionic block copolymer(EO20PO70EO20, P123) and acetic anhydride as the template and catalyst, respectively. It was inferred thatacetic anhydride could accelerate the hydrolysis of tetraethyl orthosilicate and the obtained by-product ofacetic acid was harmless to the environment. The TEM analysis indicated that the synthesized MBG had two-dimensional (2D) hexagonal mesostructures, and the measured BET surface area, pore volume and porediameter were 499 m2/g, 0.70 cm3/g and 6.1 nm, respectively. Moreover, the synthesized MBG showed anexcellent bioactivity in vitro as assessed by immersion studies in simulated body ﬂuid (SBF). In a word, thiswork presents a simple and environment friendly route for synthesizing MBG by use of acetic anhydride asthe catalyst and would ﬁnd potential applications in tissue engineering and other ﬁelds.
