TiO2/Cu2O/CuO multi-nanolayers highly sensitive toward volatile organic compounds (VOCs) and H2 have been grown in various thicknesses by a cost-effective reproducible combined spray–sputtering–annealing approach. The ultrathin TiO2 films were deposited spray pyrolysis on top of sputtered–annealed Cu2O/CuO nanolayers to enhance their gas sensing performance improve protection against corrosion ...

Facile synthesis of homoallylic alcohols is achieved from allyl halides and aldehydes or ketones over an all-oxide heterogenous media involving beta-SnO and catalytic Cu2O.

Die elektrochemische Umwandlung von Nitrat in Ammoniak ist ein wichtiger und nachhaltiger Ansatz zur Wiederherstellung des weltweit gestörten Stickstoffkreislaufs. rationale Entwicklung Katalysatoren für die Nitratreduktionsreaktion (NO3RR) auf der Grundlage eines detaillierten Verständnisses Reaktionsmechanismus großer Bedeutung. Wir berichten über einen Cu2O+Co3O4-Tandemkatalysator, NH3-Produ...

Mixing TiO2 with Mo2C has recently been proposed to improve the photocatalytic conversion of CO2 methanol under visible light irradiation, although further efforts are still needed enhance process performance. In this context, use p-type semiconductors (i.e., Cu2O) in co-doping strategies can not only redistribution electric charges due its narrowing bandgap, but also selectivity reaction towar...

The selective oxidation of styrene with highly efficient, environmentally benign, and cost-effective catalysts are great importance for sustainable chemical processes. Here, we develop an in situ self-assembly strategy to decorate Cu-based metal-organic framework (MOF) Cu-BDC-NH2 nanocrystals on Cu2O octahedra construct a series Cu2O@Cu-BDC-NH2 styrene. Using H2O2 as green oxidants, the optimiz...

A series of copper-based systems containing two different nanocomposites (Cu2O/CuO and Cu2O/Cu) was synthesized by the egg white assisted auto-combustion route. This method distinguished simplicity its steps, low cost, one-pot synthesis process at temperature and, short time. The characterization as prepared carried out using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning ...

This thesis presents a new experimental setup for surface analysis studies, incorporating chemical information from infrared reflection absorption spectroscopy (IRAS) and quantitative information from quartz crystal microbalance (QCM). The integrated IRAS/QCM surface analysis system enables in situ studies to be conducted of the metal/atmosphere interaction on a sub-monolayer level. In combinat...

Ethylene is an ideal CO2 product in electrocatalytic reduction reaction (CO2RR) with high economic value. This paper synthesised Al-doped octahedral Cu2O (Al–Cu2O) nanocrystal by a simple wet chemical method. The selectivity of CO2RR products was improved doping Al onto the surface Cu2O. Al–Cu2O used as efficient electrocatalyst for selective ethylene production. exhibited % Faradic efficiency ...

Atomic layer deposition (ALD) of alumina using trimethylaluminum (TMA) has technological importance in microelectronics. This process has demonstrated a high potential in applications of protective coatings on Cu surfaces for control of diffusion of Cu in Cu2S films in photovoltaic devices and sintering of Cu-based nanoparticles in liquid phase hydrogenation reactions. With this motivation in m...

Hollow metal oxide nanocrystals were prepared by etching cuprous oxide with metal ions and were applied as photoelectrodes. As a hard template, polyvinylpyrrolidone stabilized cuprous oxide (PVP-Cu2O) and non-stabilized cuprous oxide (nPVP-Cu2O) were synthesized by a precipitation method. Hollow iron oxide and cobalt oxide nanocrystals with a truncated octahedral morphology were fabricated by a...
