Multiple transition metal oxide mesoporous nanospheres with controllable composition for lithium storage†

A general synthetic method based on a solvothermal route for the preparation of multiple transition metal
oxide (MTMO) mesoporous nanospheres (ZnaNibMncCodFe2O4, 0 # a, b, c, d # 1, a + b + c + d ¼ 1) with
controllable composition and uniform size distribution has been developed. The as-prepared
ZnaNibMncCodFe2O4 nanospheres are formed by self-assembly of nanocrystals with the size of 5–10 nm
via structure-directing agents and mineralizer coordinating effect as well as optimization of the synthesis
conditions. It has been identified that the addition of mineralizer is crucial for the control of the
nucleation process when the metallic precursors are reduced; meanwhile the structure-directing agent
is key to forming the mesoporous structure. A number of characterization techniques including X-ray
diffraction, transmission electron microscopy, scanning electron microscopy, inductively coupled plasma
optical emission spectrometry, temperature-programmed reduction, and nitrogen adsorption have been
used to characterize the as-prepared mesoporous products. The overall strategy in this work extends the
controllable fabrication of high-quality MTMO mesoporous nanospheres with designed components and
compositions, rendering these nanospheres with promising potential for various applications (oxygen
reduction reaction, magnetic performance, supercapacitor, lithium-ion batteries, and catalysis).
