In this communication, we report a facile approach to constructing catalytic active hierarchical interfaces in 1-dimensional (1D) nanostructure, exemplified by the synthesis of TiO2-supported PtFe-FeOx nanowires (NWs). The hierarchical interface, constituting of atomic level interactions between PtFe and FeOx within each NW and the interactions bet...
Controlling nanoparticle (NP) surface strain, i.e. compression (or stretch) of surface atoms, is an important approach to tune NP surface chemistry and to optimize NP catalysis for chemical reactions. Here we show that surface Pt strain in the core/shell FePt/Pt NPs with Pt in 3 atomic layers can be rationally tuned via structure transition of FePt...

Several weeks prior to the announcement of the investigation, Ling continued to make appearances on state television in his positions of CPPCC Vice Chairman and United Front chief. On December 15 Ling had penned an article on the Communist theory publication Qiushi brimming with praise for the signature political philosophies of Xi Jinping such as the "Chinese Dream". This was seen by observers as a 'last-ditch' declaration of fealty to the new Chinese leader with whom Ling was thought to have lost favour.[11]
CO oxidation is an important reaction both experimentally and industrially, and its performance is usually dominated by the surface charge state. For example, CO oxidation on platinum (Pt) surface requires a proper charge state for the balance of adsorption and activation of CO and O2. Here, we present a “Mott−Schottky modulated catalysis” on Pt na...
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
