Book Synopsis Supercritical Fluid Nanotechnology by : Concepcion Domingo Pascual
Download or read book Supercritical Fluid Nanotechnology written by Concepcion Domingo Pascual and published by Pan Stanford. This book was released on 2015-05-31 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental and climate program demands technological solutions in the chemical industry that incorporate prevention of pollution. Major advances are needed to reduce the use of organic solvents, such as methanol, toluene, xylene, methyl ethyl ketone, and dichloromethane, which account for 27 percent of total toxics release inventory chemicals. The replacement of those solvents is a key point to enable the transition from classical synthesis to green chemistry and nanotechnology concepts, i.e., to sustainability. The first radical option to achieve this goal is to completely avoid the use of solvents, as occurs in mechanochemical processes. A wide-range synthesis prospect is given by identifying between known solvents those with less negative environmental impact. This book concerns the analysis of the advantages of using compressed CO2 to produce not only improved materials in a better way, but also new nanoproducts. Recovering and using CO2, otherwise released into the atmosphere, is a means of recycling emissions resulting from other users. The use of supercritical CO2 is a complex option from a conceptual point of view requiring enhanced technical preparation.

Download or read book Synthesis of Nanostructured Materials by Etching in Supercritical Carbon Dioxide written by and published by . This book was released on 2009 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical CO2(scCO2) is emerging as a viable and environmentally sustainable platform for nanomaterials synthesis due to its tunable solvent properties combined with low surface tension and viscosity, which allow rapid, non-destructive wetting within small features. However, to advance the utility of this fluid, a more thorough understanding of surface chemistry at high pressures is needed. In this study, the behavior of reactive solids in scCO2was examined by etching thin dielectric, metal, and alloy films to determine the fundamental mechanisms controlling the reactions. Models were developed to describe the etching processes and to benchmark scCO2with conventional methods. Dielectric SiOxNyfilms were etched with an HF/pyridine complex dissolved in scCO2. The anhydrous etching process resulted in formation of a residual (NH4)2SiF6layer that limited transport of reactants to the film and caused a drop in reaction order. Partial removal of the salt was accomplished by sublimation under vacuum. Etching of thin CuO films with hexafluoroacetylacetone (hfacH) in scCO2was studied and found to occur via a 3-step Langmuir-Hinshelwood reaction sequence. The kinetic model showed that lower scCO2densities favored hfacH adsorption on the CuO surface and that scCO2solvation forces lowered the activation barrier for the rate-limiting step. Adding up to 10 & times the molar ratio of pure H2O to hfacH nearly doubled theetching rate through formation of a hydrogen-bonded hfacH complex. Both bulk and thin film AgCu alloys were selectively etched in scCO2to generatenanoporous Ag structures. As Cu was preferentially removed through selective oxidation and chelation, the Ag atoms conglomerated into successively larger clusters similar to mechanisms reported in aqueous phase dealloying. Supercritical dealloying was observed at Cu compositions below typical parting limits, suggesting enhanced fluid transport in the evolving pores. When using in situ oxidation, the etching reaction was limited by decomposition of H2O2. Inverse space image analysis of samples with initial phase domain sizes between 250 - 1000 nm showed that below a threshold of approximately 500 nm, the dealloyed feature size mimicked the starting microstructure. Larger phase domains prohibited surface diffusion of Ag between phases producing a mixture of large and small Ag nanostructures.
