Hollow Silica Cubes with Customizable Porosity

Hollow silica cubes were synthesized by a deposition of a thin silica shell onto micrometer-sized hematite cubes. Ordered mesopores with well-defined pore diameters of 2.8 nm and 3.8 nm were introduced into the silica shell by means of pseudomorphic transformation after removal of the hematite core. The particles retained their cubic morphology upon pseudomorphic transformation, allowing for the preparation of close-packed layers of the hollow mesoporous silica cubes by drop-casting and the visualization of the hollow core by focused ion beam scanning electron microscopy.

Hierarchically organized materials with ordered mesopores: adsorption isotherm and adsorption-induced deformation from small-angle scattering

Apparent strain artifacts resulting from the evaluation of small-angle X-ray scattering data superimpose the actual adsorption induced deformation in silica with hierarchical porosity. These artifacts can be corrected for by detailed modelling.

A small-strain niobium nitride anode with ordered mesopores for ultra-stable potassium-ion batteries

Niobium nitride is first reported as an ultra-stable anode for KIBs. The superior electrochemical performance is attributed to large host for accommodating K ions with small-strain, and a high portion of the surface-controlled reaction.

Heterogeneity of polyoxometalates by confining within ordered mesopores: toward efficient oxidation of benzene to phenol

Polyoxometalates@ordered mesoporous polymers have been prepared by a mechanochemical coordination assembly with tannin as the renewable precursor.

The facile synthesis and enhanced photocatalytic activity of a graphitic carbon nitride isotype heterojunction with ordered mesopores

In order to improve the photocatalytic activity of graphitic carbon nitride, we prepared a g-C3N4 isotype heterojunction with ordered mesopores through simple one-step calcination.
