The application of gold-supported nanocomposites is useful in clinical diagnostics because of their ability to provide bio-compatible and sensitive detection systems. A gold-supported magnesium hydroxide and cerium oxide nanocomposite framework (Au/MgCe-HDO) was synthesized and characterized via XRD, XPS, SEM, DLS, TEM, and TGA techniques. The nanocomposite was used as a selective catalyst for the aerobic oxidation of alcohols under mild reaction conditions followed by successive condensation reactions, like Knoevenagel and Claisen-Schmidt condensation. Substituted benzyl alcohols were converted into the corresponding carbonyl compounds in the presence of the Au/MgCe-HDO nanocomposite with O2 gas and toluene as a solvent. We observed that, upon the addition of malononitrile/ethyl cyanoacetate/acetophenone to the catalyst in the aerobic oxidation reaction, the reaction proceeds to produce the corresponding desired condensation product with up to 95% yield.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were pol
