It is indicated that the heterostructured combination of g-C3N4, Ag and TiO2 microspheres provides synergistic photocatalytic activity through an efficient electron transfer process. Expand
Influence of Speciation of Aqueous HAuCl4 on the Synthesis, Structure, and Property of Au Colloids
We have studied the pH-dependent speciation of aqueous HAuCl4 and its influences on the synthesis, structure, and property of Au colloids. Aqueous HAuCl4 consists of [AuClx(OH)4−x]− (x ≥ 2) at low pH… Expand
Structure-activity Relation of Fe2O3–CeO2 Composite Catalysts in CO Oxidation
A series of Fe2O3–CeO2 composite catalysts were synthesized by coprecipitation and characterized by X-ray diffraction (XRD), BET surface area measurement, Raman spectroscopy, and X-ray photoelectron… Expand
Understanding complete oxidation of methane on spinel oxides at a molecular level.
It is reported that the higher catalytic activity at the relatively low temperature results from the integration of nickel cations, cobalt cations and surface lattice oxygen atoms/oxygen vacancies at the atomic scale. Expand
Spectroscopic studies of interfacial structures of CeO2-TiO2 mixed oxides
Abstract We have investigated the geometric and electronic structures of the cerium oxide (CeO 2 )–titanium dioxide (TiO 2 ) mixed oxides with various Ce/TiO 2 weight ratios prepared by the sol–gel… Expand
Formation of subsurface oxygen species and its high activity toward CO oxidation over silver catalysts
Silver is well known to show peculiar catalytic activities in several oxidation reactions. in the present paper, we investigate the catalytic activity of silver catalysts toward co-gelective… Expand
Shape-dependent interplay between oxygen vacancies and Ag–CeO2 interaction in Ag/CeO2 catalysts and their influence on the catalytic activity
Abstract Ag/CeO 2 catalysts employing CeO 2 nanocubes ( c -CeO 2 ) and nanorods ( r -CeO 2 ) as the support were prepared by conventional incipient wetness impregnation followed by calcination at 500… Expand

The results unambiguously show that Cu2 O itself can act as the highly active and stable cocatalyst for photocatalytic water reduction. Expand
Large scale photochemical synthesis of M@TiO2 nanocomposites (M = Ag, Pd, Au, Pt) and their optical properties, CO oxidation performance, and antibacterial effect
AbstractWell-dispersed M@TiO2 (M = Ag, Pd, Au, Pt) nanocomposite particles with a diameter of 200–400 nm can be synthesized on a large scale by a clean photochemical route which does not require any… Expand
