Construction of Defect-Engineered Three-Dimensionally Ordered Macroporous WO3 for Efficient Photocatalytic Water Oxidation Reaction

To improve solar light harvesting and charge separation efficiency, we develop a facile strategy for synthesizing defect-engineered three-dimensionally ordered macroporous (3DOM) WO3 photonic crystals via colloidal crystal template method and...

Optimum selective separation of Cu(ii) using 3D ordered macroporous chitosan films with different pore sizes

3DOM-IICF coupled with colloidal crystal template and ion imprinting technology (IIP) was used to absorb copper ions (Cu(ii)) in water. Added polystyrene (PS) micro-spheres to form a three-dimensional ordered macroporous structure.

Size-tunable CsPbBr3 perovskite ring arrays for lasing

The first reported CsPbBr3 perovskite ring array with tunable ring sizes from 2.6 μm to 16.9 μm was fabricated by using a 2D polystyrene colloidal crystal template and is expected to be used in the fields of display and lasers.

Three-dimensionally ordered macroporous Sn4+-doped TiO2 with anatase–rutile mixed phase via Pt loading by photoreduction method: enhanced photodegradation and hydrogen production performance

3DOM Pt/Sn–TiO2 with anatase–rutile mixed phase was successfully prepared by the colloidal crystal template method and the photoreduction method. A series of photocatalytic experiments showed that 3DOM Pt/Sn–TiO2 exhibited significant photocatalytic activity in photodegradation and water splitting.

Preparation of pocket shaped microfiltration membranes with binary porous structures

Pocket-shaped microfiltration membranes with binary porous structures were prepared on needles by combining the breath figure (BF) method and the colloidal crystal template (CCT) method.

Oxygen vacancy-related room temperature ferromagnetism in TiO2 nanohole arrays

Room temperature ferromagnetism was observed in hole-like TiO2 nanostructure arrays prepared by a monolayer colloidal crystal template.
