We report a simple and facile self‐assembly method for the successful fabrication
of a biological macromolecule, MnTPPCl (manganese(III) chloride
5,10,15,20‐tetraphenylporphyrin), intercalated into gold nanoparticles using
the cooperative effects of Sesbania sesban plant. This biohybrid was characterized
using various techniques for further investigation. The catalytic activity of
this biological hybrid was considered in the production of aldehydes and
ketones from primary and secondary alcohols, respectively. Excellent conversions
and selectivties were obtained applying Au@MnTPPCl colloidal nanocomposite
and NaIO4 as an oxygen donor in ethanol.
