Closed-cell aluminum foam with different percentages of Cu was prepared by melt foaming method.The effect of Cu element on the quasi-static compressive properties of aluminum foam was investigated, both under as-cast and heat-treated conditions. The results showed that Cu element distributed in cell wall matrix mainly in the forms of Al-Cu solid solutions and AlCu3, Al6.1Cu1.2Ti2.7 intermetallics. Meanwhile, Cu-containing foams possessed much higher compressive strength than the commercially pure aluminum foams.

In this mini-review we compare two prototypical metal foam electrocatalysts applied to the transformation of CO2 into value-added products (e.g. alcohols on Cu foams and formate on Bi foams). A substantial improvement in the catalyst performance is typically achieved through thermal annealing of the as-deposited foam materials, followed by the electro-reduction of the pre-formed oxidic precursors prior or during the actual CO2 electrolysis. Utilizing highly insightful and sensitive complementary operando analytical techniques (XAS, XRD, and Raman spectroscopy) we demonstrate that this catalyst

Abstract Structured Pd/Al2O3 catalysts were fabricated by impregnating Pd onto Ni and Cu foams coated with Al2O3 layers. By testing the adhesion stability and catalytic activity in the combustion of methane, the superior performance of Ni-foam-supported Pd/Al2O3 catalyst was demonstrated, to its counterpart powder catalysts. The resultant structured catalysts enable the fabrication of lamellar microreactor systems. It is found that the metal foams influence the activity of catalyst layer, due to the diffusive penetration of metallic atoms into catalysts from metal foams. The Ni foam is benefic

The synthesis of Cu(OAc)2(en)2-EG and Cu(OAc)2(trien)-EG is convenient because the synthesis of copper-amine complexes can be done in situ using ethylene glycol as a solvent and no purification step is needed.

The application-attractive form of TiO2, CeO2 and CuO-based open-cell foam supported catalysts was designed to investigate their catalytic performance in oxidation of two model volatile organic compounds—methanol and dichloromethane. TiO2-CeO2, TiO2-CuO and TiO2-CeO2-CuO catalysts as thin films were deposited on VUKOPOR®A ceramic foam using a reverse micelles-controlled sol-gel method, dip-coating and calcination. Three prepared catalytic foams were investigated via light-off tests in methanol and dichloromethane oxidation in the temperature range of 45–400 °C and 100–500 °C, respectively, at

Superconducting foams of YBa 2 Cu 3 O y (YBCO) are proposed as trapped field magnets or supermagnets. The foams with an open-porous structure are light-weight, mechanically strong and can be prepared in large sample sizes. The trapped field distributions were measured using a scanning Hall probe on various sides of an YBCO foam sample after field-cooling in a magnetic field of 0.5 T produced by a square Nd-Fe-B permanent magnet. The maximum trapped field (TF) measured is about 400 G (77 K) at the bottom of the sample. Several details of the TF distribution, the current flow and possible applic

Cell wall material properties of Al-alloy foams have been derived by a combination of nanoindentation experiment and numerical simulation. Using the derived material properties in FE (finite element) modeling of foams, the existing constitutive models of closed-cell Al-alloy foams have been evaluated against experimental results. An improved representative model has been proposed for FE analysis of closed-cell Al-alloy foams. The improved model consists of a combination of spherical and cruciform-shaped cells similar to those of Meguid et al.'s cruciform-hemisphere model (Finite Elem. Anal. De

As part of laser-matter interaction experiments carried out on the LMJ facility, CEA needs to synthesize metallic foams with specific characteristics. The goal is to fabricate at millimetric scale, metallic foam samples with a density lower than 10% of the bulk material and structured with a micrometric porosity (< 5 µm). To obtain these specific materials, CEA has developed an innovative process using plasma electrolysis technique to grow metallic foam at a cathode surface.

The Ag/Ni(OH)2 composite has grown directly on Cu foam substrate via a modified galvanic displacement reaction between the mixed solution (AgNO3 and KBr) and Cu foam, followed by subsequent electrodeposition. Cu foam functions as a reducing agent and electrode substrate. The in situ growth strategy enables the active material to form a strong connection with the substrate, which is beneficial for the fast ionic/electronic transport and lowers the equivalent series resistance. On the other hand, the introduction of Ag improves the electrical conductivity of the material and increases the specif

Oil pollution in the ocean has been a great threaten to human health and the ecological environment, which has raised global concern. Therefore, it is of vital importance to develop simple and efficient techniques for oil–water separation. In this work, a facile and low-cost laser-heat surface treatment method was employed to fabricate superwetting copper (Cu) foam. Nanosecond laser surface texturing was first utilized to generate micro/nanostructures on the skeleton of Cu foam, which would exhibit superhydrophilicity/superoleophilicity. Subsequently, a post-process heat treatment would reduce

Conversion of CO2 into valuable chemicals and fuels has received widespread attention as a way to tackle the increased CO2 emissions (Gattrell, Gupta and Co, 2006) and this also resulted in a reduction of dependence on fossil fuels . There are different techniques for CO2 conversion to value-added products, where electrochemical reduction (ECR) of carbon dioxide into chemical fuels is identified as a promising way since energy efficiency is high and the products, especially the chemical fuels can be readily stored.

Abstract:A synthesis method to form foams consisting of a shell of metals conformally coated on carbon nanotube (CNT) arrays by electroplating from a single bath electrolyte is demonstrated in this work. A triple cyclic pulse electrodeposition technique was used to deposit Ni and Cu layers on the CNT arrays, and electron microscopy was then used to identify conditions amenable to semi-conformal and island growth morphologies. Nanoindentation of the resulting metallic-CNT composite foam structure, using a flat punch/compression geometry, demonstrates that adding metallic shells to the CNT turf
