Toward highly efficient photocatalysis: a flow-through Pt@TiO2@AAO membrane nanoreactor prepared by atomic layer depositionElectronic supplementary information (ESI) available. See DOI: 10.1039/c4cc01166j

A Pt@TiO 2 @AAO membrane nanoreactor was fabricated by atomic layer deposition. The photodegradation test of methylene blue demonstrated that the nanoreactor shows efficient photocatalysis performance. It exhibited ∼28% photodegradation of methylene blue after ten flow-through cycles, corresponding to about 2.7 × 10 −2 s of contact time of methylene blue with Pt@TiO 2 nanotubes. A Pt@TiO 2 @AAO membrane nanoreactor was fabricated by atomic layer deposition.
