Preparation and assembly of SiO<sub>2</sub>@TiO<sub>2</sub> photoresponsive colloidal rings
We report the synthesis of SiO<sub>2</sub> colloidal rings coated with TiO<sub>2</sub>, which enable photoresponsive self-assembly into porous ordered structures and hybrid assembly for the capture and release of non-active colloids in a hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) solution. Such assemblies originate from a concentration gradient generated by the TiO<sub>2</sub>-mediated decomposition of H<sub>2</sub>O<sub>2</sub> under ultraviolet (UV) irradiation. The work provides a straightforward strategy to fabricate active colloids with ring-like shapes for the controlled assembly of open crystalline colloidal materials.
