Synthesis of hierarchical mesoporous Ln2Ti2O7(Ln=Y,Tb-Yb)pyrochlores and uranyl sorption properties
文献摘要：
Mesoporous structured metal oxides exhibit many active applications.However,the synthesis of crys-talline metal oxides with a ternary composition while maintaining satisfactory pore features is challeng-ing.Typically,high temperatures are required which inhibit control of pore structure properties including surface area,pore volume,and pore size.Herein,the synthesis of ternary metal oxides Ln2Ti2O7 pos-sessing pyrochlore crystal structure is achieved using a novel technique which combines'soft'and hard colloid templating strategies.The formed materials are of submicron size and composed of～25-30 nm product'building blocks'with good chemical and phase stability.The polycrystalline powders have a high specific surface area(up to 70 m2·g-1)and pore volume(～0.35 cm3·g-1)which result in a good adsorp-tion capacity(U uptake closing to 60 mg·g-1).Remarkably,the material exhibits a significant portion of mesopores(mainly 10-40 nm)which facilitate fast adsorption of the cations due to high accessibility.The synthetic methodology described herein produces highly homogenous powders and can be applied to other compositions and structures.
