In this study, semiconductor oxide cuprite (Cu2O) and indium tin (ITO) heterojunction solar cells with without a 10 nm thick titanium (Ti) thin film as the buffer layer were fabricated characterized for comparison. The Cu2O was formed by low-cost electrodeposition, Ti ITO layers deposited on glass substrate sputtering. interfacial microstructures, surface topology, electrical photovoltaic prope...

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...

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...
