New Cu2O@TiO2 core-shell microspheres were successfully prepared for the first time in this paper. The XRD, N2 adsorption-desorption, SEM, TEM, EDX and XPS characterizations utilized to investigate physical chemical properties. liquid phase oxidation of naphthalene was also carried out test their catalytic performance. characterization results indicating that Cu2O firstly formed by hydrothermal...

Cu-oxide nanophases (CuO, Cu2O, Cu0) constitute highly potent nanoplatforms for the development of efficient Artificial Photosynthesis catalysts. The reducing conduction band edge d-electrons in Cu2O dictates its efficiency towards CO2 reduction under sunlight excitation. In present review, we discuss aspects interlinking stability photocorrosion (CuO/Cu2O/Cu0) nanophase equilibria, and perform...

The electrocatalytic CO2 reduction technology is expected to simultaneously alleviate increasing emissions and the depletion of fossil resources. However, it still a big challenge improve selectivity toward valuable multi-carbon products in reaction. In this study, synergistic role Cu+ Cu0 species Cu2O-Cu interfaces unravelled through density functional theory (DFT) calculations, which electrod...

Cu2O nanodots have been grown on LaAlO3 (0 0 1) substrates using metalorganic chemical vapor deposition. X-ray diffraction reveals that the nanodots grow epitaxially on the substrate. The dots are hut-shaped islands with {1 1 1} side facets. Evolution of the nanodot shape, density, and size during growth has been analyzed by scanning electron microscopy and atomic force microscopy. It is shown ...

We find that nearly monodisperse copper oxide nanoparticles prepared via the thermal decomposition of a Cu(I) precursor exhibit exceptional activity toward CO oxidation in CO/O2/N2 mixtures. Greater than 99.5% conversion of CO to CO2 could be achieved at temperatures less than 250 degrees C for over 12 h. In addition, the phase diagram and pathway for CO oxidation on Cu2O (100) is computed by a...

In this work we investigated the surface and facet-dependent catalytic properties of metal oxide particles as well as noble metal/metal oxide heterogeneous structures, with cuprous oxide (Cu(2)O) and Au/Cu(2)O being selected as model systems. As an example of application, we explored the potential of these materials in developing electrocatalytic devices. Cu(2)O particles were synthesized in va...

Solar light-driven hydrogen by photocatalytic water splitting over a semiconductor photoelectrode has been considered promising green energy carrier. P-type semiconducting copper oxides (Cu2O and CuO) have attracted remarkable attention as an efficient photocathode for photoelectrochemical (PEC) because of their high solar absorptivity optical band gaps. In this study, CuO thin films were prepa...
