From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts
Advanced Functional Materials, EarlyView.Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Polypropylene/layered double hydroxide nanocomposites
Journal of Materials Chemistry, 2012 We report a novel synthesis method for the preparation of polypropylene/layered double hydroxide (PP/LDH) nanocomposites, in which LDH nanosheets, [Mg2Al(OH)6](DDS)·2H2O (Mg–Al–DDS), were prepared using a one-step reverse microemulsion method. PP/LDH nanocomposites were prepared by direct mixing of the obtained LDH nanosheets with PP in xylene at 140 ...
