The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-abundant and inexpensive copper metal, have generated a great deal of interest in recent years, especially in the field of catalysis. The possible modification of the chemical and physical properties of these nanoparticles using different synthetic strategies and conditions and/or via postsynthetic chemical treatments has been largely responsible for the rapid growth of interest in these nanomaterials and their applications in catalysis. In addition, the design and development of novel support and/or multimetallic systems (e.g., alloys, etc.) has also made significant contributions to the field. In this comprehensive review, we report different synthetic approaches to Cu and Cu-based nanoparticles (metallic copper, copper oxides, and hybrid copper nanostructures) and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications in catalysis. The synthesis part discusses numerous preparative protocols for Cu and Cu-based nanoparticles, whereas the application sections describe their utility as catalysts, including electrocatalysis, photocatalysis, and gas-phase catalysis. We believe this critical appraisal will provide necessary background information to further advance the applications of Cu-based nanostructured materials in catalysis.

Synthesis, Characterization and Application of Bisphenol …

The most common and important epoxy compound is the diglycidyl ether of bisphenol A, which is formed from reacting epichlorhydrin with bisphenol A. The industrial grades normally contain some distribution of molecular weight, since pure DGEBA shows a strong tendency to form a crystalline solid upon storage at ambient temperature. If exactly two moles of epichlorhydrin are reacted with one mole of bisphenol A the product is the bisphenol A diglycidyl ether, commonly abbreviated to DGEBA. Increasing the ratio of bisphenol A to epichlorhydrin during synthesis produces higher molecular weight linear polyethers with glycidyl end groups, which are semi-solid to hard crystalline materials at room temperature depending on the molecular weight achieved. As the molecular weight of the resin increases, the epoxide content reduces and the material behaves more and more like a thermoplastic. Very high molecular weight polycondensates of 30 000 – 70 000 g/mol are known as phenoxy resins and contain virtually no epoxide groups since the amount of terminal epoxy groups is insignificant compared to the total weight of the molecule. These resins do however contain hydroxyl groups throughout the backbone, which may also undergo crosslinking reactions, i.e. they can react with isocyanates etc.
