Examples of the Preparation and Use of Homogeneous CatalystsThe methods of preparation of some more generally useful homogeneous catalysts are summarised below.doi:10.1007/978-94-010-1878-4_11F. J. McQuillinSpringer Netherlands
Types of catalysts A catalyst is a chemical compound which makes the reaction occur more quickly by reducing the reaction’s activation energy barrier. During the reaction it isn’t eaten. Homogeneous catalyst –Homogeneous catalysts are usually soluble metal salts or compounds that are dissolved in...

Immobilisation of Homogeneous Catalysts in Metal-Organic Frameworks: Methods and Selected Examples The biosynthesis of the active site of the [FeFe]-hydrogenases (H-cluster) remains a tantalizing puzzle due to its unprecedented and complex ligand environment. It contains a [2Fe] cluster ([2Fe](H)...
In this context, efforts to convert CO2 to useful chemicals will inevitably rely on its activation through molecular catalysts, particularly transition-metal catalysts. Two preparative processes employing solid catalyst or CO2-philic homogeneous catalyst were devised for environmentally benign synthesis of ...

Sol-gel technology allows better mixing of the ceramic components at the molecular level, and hence yields more homogeneous ceramics, because the ions are mixed while in solution. In the sol-gel process, a solution of an organometallic compound is hydrolyzed to produce a "sol," a colloidal sus...
A possible solution is the development of processes using enzymatic, homogeneous or heterogeneous catalysts. In this review, selected examples of clean heterogeneously-catalyzed reactions applied to the synthesis of fine chemicals are reported for the purpose of highlighting the growing need for more ...

In this review paper, we define and describe positive and negative catalysis in enzymes and compare structure and reactivity with biomimetic and homogeneous catalysts for a number of mononuclear iron-type enzymes including the cytochromes P450 and non-heme iron dioxygenases....
