Catalysis Reviews 作为催化领域权威的综述合集,今年年末的第四期主要侧重在Ni基的F-T合成及酶类的均相催化： Nickel and Fischer-Tropsch Synthesis Abstract: Nickel has been reviewed as a catalyst and promoter in the Fischer-Tropsch synthesis (FTS). The main obstacle to its industrial application is the formation of volatile carbonyls, causing deactivation and loss of active phase, as well as a somewhat lighter product than from Co or Fe catalysts. Presented are both experimental and theoretical work pointing to suitable techniques for catalyst preparation, its composition and activation, as well as operating conditions where Ni is capable of producing long chain hydrocarbons in the FTS. Some important perspectives are also provided based on thermodynamic calculations and suggestions for further work are included. ------------------------------------------------------------------------------------ The Outer-Coordination Sphere: Incorporating Amino Acids and Peptides as Ligands for Homogeneous Catalysts to Mimic Enzyme Function Abstract: Great progress has been achieved in the field of homogeneous transition metal-based catalysis; however, as a general rule these solution-based catalysts are still easily outperformed by their analogous enzyme counterparts, in terms of both rates and selectivity. This includes structural mimics of enzymatic active sites. This observation suggests that the features of the enzyme beyond the active site, i.e., the outer-coordination sphere, are important for enzymes' exceptional function. Directly mimicking the outer-coordination sphere requires the incorporation of amino acids and peptides as ligands for homogeneous catalysts. This effort has been attempted for many homogeneous catalysts which span the manifold of catalytic reactions including hydrogenation, hydroformylation, hydrogen production, oxygen activation, dioxygen transport, electron transfer, disproportionation of the superoxide anion radical, acylation, phosphorylation, esterification, ester hydrolysis, and hydrogen peroxide disproportionation. How much of the outer-coordination sphere to include in molecular catalysts and the preferential structural conformation of the appended section are long-standing questions. Synthetically incorporating an amino acid- or peptide-based outer-coordination sphere requires care to avoid unwanted side reactions with the large number of functional groups. Catalysis with amino acid or peptide containing catalysts requires careful consideration of solvent and pH to promote solubility, stabilize structure, optimize catalysis, and avoid catalyst degradation. This article reviews the current capability of synthesizing and characterizing this often challenging but very promising category of metal-based catalysts. download links: http://good.gd/2331633.htm http://pan.baidu.com/share/link?shareid=145421&uk=4113076280 全文均在附件中，有需要的同学可以下载~[ Last edited by leiws on 2012-12-2 at 12:46 ] |
