![]() ![]() Actually, in many cases Cu is expected to play a vital role as a shell because of its high activity in diverse reactions. AuCu2O core-shell nanoparticles (NPs) were synthesized by a solution method at room temperature and applied for gas sensor applications. So far, literature reporting the successful synthesis of such a structure is very scarce, if any. As a result, it is a challenging task to fabricate the structure with Cu2O core and Cu shell the opposite construction to the usual core-shell structure. This method, in combination with oxidative reactions of Cu, has been widely used to generate coreshell structure with Cu core and Cu2O shell However, in contrast to oxidization that can be easily realized by various methods, the light transition metal Cu is difficult to obtain via the reduction of Cu oxides in solution. Cu2O as the Self-Template to Prepare Cu2OCeO2 Coreshell Nanocubes. Actually, in many cases Cu is expected to play a vital role as a shell. CeO2-Al2O3 (8:92 mol ) mixtures (Figures 10D10F),34 and macrocellular mesopo. So far, literature reporting the successful synthesis of such a structure is very scarce, if any. A highly selective and low-cost Cu 2 OSnO 2 core-shell electrocatalyst is reported, achieving CO 2-to-CO conversion with a faradaic efficiency higher than 90 at a low overpotential of 390 mV, which is comparable to noble metal catalysts.The catalyst was synthesized using a simple and straightforward method without the use of any surfactant or capping agent. In general, sacrificial template-directed chemical transformation,īased on the Kirkendall effect, is an effective approach to fabricateĬore-shell structures. As a result, it is a challenging task to fabricate the structure with Cu2O core and Cu shell (Cu2OCu), the opposite construction to the usual CuCu2O core-shell structure. Among various morphologies, coreshell structures are of significant interest owing to their unique architecture, bifunctional characteristics, and enhanced activity. It is well known that morphology has an important effect on both physical and chemical properties therefore, much attention has been paid to controllable construction of materials. Great interest due to their excellent performance in the field of catalysis, superconductivity, photovoltaics, magnetic storage, electrochemistry, and biosensing. As low-cost and versatile materials, Cu and its oxides have attracted ![]()
