Preparation nano TiO_2 mesoporous material by soft template
Source abstract
Abstract
The triblock copolymer of ethylene oxide with propylene oxide(EO20PO70EO20,call as P123) was used as template agent,titanium(IV) isopropoxide(TTIP) was used as the inorganic precursor and hydrochloric acid was used as catalyst in the study.Mesoporous TiO2 materials were obtained by soft template method through old and calcination.The structure,morphology,crystalline size,specific surface area and pore size of the resulting samples were characterized by X-ray diffraction,HRTEM and N2 absorption-desorption techniques.The results show that obtained sample heat-treated at 400℃ arrays ordered mesoporous partly and owns high brunauer-emmett-teller(BET) surface area through changing ratio of TTIP,P123 and ethanol.
