Glucose-mediated template-free synthesis of hollow CuO microspheres

Template-free synthesis and luminescent properties of hollow Ln:YOF (Ln = Eu or Er+Yb) microspheres

A template-free method for stable CuO hollow microspheres fabricated from a metal organic framework (HKUST-1).

Uniform CuO hollow microspheres were successfully achieved from a non-uniform metal organic framework by using a template-free method. The process mechanism has been revealed to be spherical aggregation and Ostwald ripening. When tested in CO oxidation and heat treatment, these assembled microspheres exhibited an excellent catalytic performance and show a much better stability than the inherite...

Bifunctional highly fluorescent hollow porous microspheres made of BaMoO 4 : Pr 3 + nanocrystals via a template - free synthesis †

nanocrystals by a facile template-free synthesis. All the as-synthesized hollow microspheres are welldispersed with a diameter of 2–4 mm and the BaMoO4 : Pr 3+ nanocrystals measure 30–60 nm in diameter. It is observed that there are a large amount of pores with an average diameter is 17.5 nm in the shell of these BaMoO4 : Pr 3+ hollow microspheres, thereby exhibiting a great promise for drug de...

Template-Free Fabrication of Bi2WO6 Hierarchical Hollow Microspheres with Visible-Light-Driven Photocatalytic Activity

Highly hierarchical hollow bismuth tungstate (Bi2WO6) microspheres self-assembled by thin nanoplates have been fabricated via a facile template-free solvothermal route. The possible growth pattern and formation mechanism of hierarchical hollow Bi2WO6 microspheres was investigated. The excellent visible-light-driven photocatalytic performance on rhodamine B (RhB) degradation was displayed by hie...

Synthesis and Characterization of Gd2O3 Hollow Microspheres Using a Template-Directed Method

Uniform rare-earth gadolinium oxide (Gd₂O₃) hollow microspheres, as formed through a urea-assisted homogenous precipitation process using carbon spheres as a template and a subsequent heat treatment, were characterized by using X-ray diffraction, Fourier transformed infared spectroscopy, thermogravimetry, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron micr...
