Copper–ceria as one of the very active catalysts for oxidation reactions has been widely investigated in heterogeneous catalysis. In this work, copper oxide (1 wt % Cu loading) deposited on both ceria nanospheres with a {111}/{100}-terminated surface (1CuCe-NS) and nanorod exposed {110}/{100} faces (1CuCe-NR) have prepared investigation crystal plane effects CO oxidation. Various structural characterizations, especially including aberration-corrected scanning transmission electron microscopy...
Two comparable models of BiOI/BiOCl heterojuctions with different interface structures (crystal surface orientation and crystal combination), denoted as BiOI(001)/BiOCl(001) BiOI(001)/BiOCl(010), have been prepared via integrating heterojuncton nanostructure construction facet engineering. BiOI(001)/BiOCl(010) had a greater degree lattice mismatch displayed higher visible-light photocatalytic activity than BiOI(001)/BiOCl(001). In general, the photocatalyst (ηPC) has positive correlation...
Copper-ceria is one of the very active catalysts for preferential oxidation carbon monoxide (CO-PROX) reaction, which also a typical system in complexity copper chemistry clearly exhibited. In present manuscript, copper–ceria with different Cu contents up to 20 wt % supported on CeO2 nanorods were synthesized by deposition–precipitation (DP) method. The as-prepared samples characterized various structural and textural detections including X-ray diffraction (XRD), Vis-Raman, transmission...
Fabricating heterojunction photocatalysts is an important strategy for speeding up the separation rate of photogenerated charge carriers, which attracting greater interest. However, choice three factors, individual materials, band offsets, and effective interfaces, still fabricating efficient photocatalysts. Herein, g-C3N4/Zn2GeO4 with interfaces were designed by controlling surface charges two materials inside same aqueous dispersion medium, making use electrostatic attraction between...

Abstract As the water-gas shift (WGS) reaction serves as a crucial industrial process, strategies for developing robust WGS catalysts are highly desiderated. Here we report construction of stabilized bulk-nano interfaces to fabricate efficient copper-ceria catalyst reaction. With an in-situ structural transformation, small CeO 2 nanoparticles (2–3 nm) on bulk Cu form abundant -Cu interfaces, which maintain well-dispersed under conditions. This inverse /Cu shows excellent performances,...
Dual-interfacial structure within catalysts is capable of mitigating the detrimentally completive adsorption during catalysis process, but its construction strategy and mechanism understanding remain vastly lacking. Here, a highly active dual-interfaces CeO2-x/CoO1-x/Co constructed using pronounced interfacial interaction from surrounding small CeO2-x islets, which shows high activity in catalyzing water-gas shift reaction. Kinetic evidence in-situ characterization results revealed that...

Effective gold-support interaction formed through gold nanoparticles locally generated by sintering of dispersed Au atoms on the dehydrated oxide support.
For decades, it is fairly controversial whether the active gold sites in catalyzing CO oxidation reaction are metallic or positively charged. Herein, catalysts with either charged were separately prepared by deposition–precipitation method same type of TiO2 matrix. The catalytic behaviors observed for two catalysts. initially inactive Aun+/TiO2 (1 < n 3) catalyst, situ diffuse-reflectance infrared Fourier transform spectroscopy (in DRIFTS) exhibited that induced transformation from Aun+ to...
