CuO nanostructures of different morphologies were synthesized and compared for catalytic benzene combustion. XRD patterns various nano-crystallites suggest the monoclinic structure. The dominant crystal planes are identified by means HRTEM electron diffraction. amount oxygen adspecies was found to be strongly dependent on orientation planes. activity combustion over major is: (200) > (111) (01) (001), consistent with order corresponding density terminate Cu2+ ions which both activated.

Abstract Surface/interfacial catalysis on a series of oxide substrates and metal/oxide interfaces has been reviewed. Special attention paid to those systems in which the are structurally defined with certain exposed facets, metal assembling is well controlled desired particle size narrow distribution. The distinct catalytic behaviors over selected have discussed line their specific surface/interfacial structure features as other surface properties. tactics cations how build up novel...

Abstract Dry reforming of methane has been systematically investigated over a series x ‐Co@SiO 2 ‐ y catalysts where is the Co particle size ranging from 11.1 to 121.3 nm while denotes silica shell thickness 6.0 21.9 nm. Various techniques including TEM, XRD, H ‐TPR/‐TPD, XPS, BET, O ‐TPO, TG, and ‐TPSR‐MS were employed characterize physicochemical properties catalysts. ‐TPR XPS results indicate that core–shell interaction dependent on core size: smaller is; stronger interaction. The...

Abstract The nanostructures of silica‐encapsulated NiO nanoparticles (NPs) doped with La, Ce, Ba, Co, Cu, and Fe were prepared tested as catalysts for the partial oxidation methane to syngas. Techniques that include TEM, XRD, Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectroscopy (XPS), H 2 temperature‐programmed reduction (TPR), O (TPO) employed characterize fresh used understand structure–performance relationship. La‐doped Ni@SiO catalyst is superior those other elements. effect...

A novel synthetic strategy has been adopted to deposit Au nanoparticles (NPs) (ca. 5 nm) on a hollow FeOx substrate using Au/β-FeOOH hybrid nanocrystals as the precursor. Through encapsulation of by SiO2 shells and calcination step, can be transformed into Au/FeOx with structural feature. Because protective shells, aggregation NPs is effectively prohibited, hemispherical morphology particles essentially retained. The composite obtained removing in final are small-sized yet stable enough...
