Although artificial capsule structures have been thoroughly investigated, functionality at the surfaces of their interiors has surprisingly overlooked. In order to exploit this aspect capsular structure, we here report breakthrough fabrication metallic (platinum) microcapsules with sufficient accessibility and electroactivity both interior exterior (open-mouthed platinum microcapsules), also demonstrate improvements in electrochemical catalytic functions emphasize practical importance our...
A copper(II)-oxide-based exhaust catalyst exhibits better activity than Pt- and Rh-nanoparticle catalysts in NO remediation at 175 °C. Following theoretical design, the CuO is rationally prepared; nanoplates bearing a maximized amount of active {001} facet are arranged interleaved layers. field test using commercial gasoline engine demonstrates ability to remove from small vehicles. Air pollution by automobile becoming global challenge; it not limited developing countries where traffic...
The surface electronic structure and CO-oxidation activity of Pt alloys, Pt3T (T = Ti, Hf, Ta, Pt), were investigated. At temperatures below 538 K, the activities increased in order < Pt3Ti Pt3hHf Pt3Ta. center-of-gravity d-band (the center) was theoretically calculated to follow trend Pt3Ta Pt3Hf Pt. showed a volcano-type dependence on center, where exhibited maximum activity. Theoretical calculations demonstrated that adsorption energy CO catalyst monotonically decreases with lowering...

A platinum-based intermetallic phase with an early d-metal, Pt3Ti, has been synthesized in the form of nanoparticles (NPs) dispersed on silica (SiO2) supports. The organometallic Pt and Ti precursors, Pt(1,5-cyclooctadiene)Cl2 TiCl4(tetrahydrofuran)2, were mixed SiO2 reduced by sodium naphthalide tetrahydrofuran. Stoichiometric Pt3Ti NPs average particle size 2.5 nm formed (particle size: 20−200 nm) atomically disordered FCC-type structure (Fm3̅m; a = 0.39 nm). high dispersivity was achieved...
Chemical looping combustion possesses an inherent advantage of separation CO2 from the carbon based fuels including thermal power plants that would offer effective mitigation emissions through capture and sequestration. In this study, a stable regenerative mixed transition metal oxide Cu Mn (CuMn2O4) is synthesized coprecipitation method tested for multicycle performance oxidation syngas as fuel.
