Engineering structured MOF at nano and macroscales for catalysis and separation: In this Hot Article, Sonia Aguado, Jerome Canivet and David Farrusseng from the Université Lyon 1, France, present for the first time the combination of the postfunctionalization of a MOF with its shaping as structured bodies. The team demonstrate that it is possible to achieve multiscale engineering of a MOF for catalytic and separation applications, which they claim could help create MOFs for use in industry. (J. Mater.

Nanoheterostructures on TiO2 nanobelts achieved by acid hydrothermal method with enhanced photocatalytic and gas sensitive performance: Double heterostructure TiO2 nanobelts exhibit a much higher photocatalytic activity than normal TiO2 nanobelts and single heterostructure TiO2 nanobelts say scientists at Shandong University, China and Bowling Green State University, US. Optimising the nanobelt surface nanoheterostructure provides a broad approach to modify the physical properties and should have wide applications in photocatalysts, solar cells, chemical/bio sensors, and other techniques they claim.

Pt nanocrystal evolution in the presence of Au(III)-salts at room temperature: spontaneous formation of AuPt heterodimers: A straightforward synthesis of AuPt heterodimers performed at room temperature using oleylamine as the reducer and Pt seeds has been developed by Spanish scientists. The presence of Pt nanocrystals markedly accelerates the nucleation rate of Au, which suggest it acts as both nucleation platforms and initial catalytic reducers. (J. Mater.
