The surface of magnetite (Fe 3 O 4 ) nanoparticles was subject to modification through the incorporation of L-proline (LP) by simple co-precipitation method in which silver nanoparticles were deposited by in situ method, thereby yielding the Fe 3 O 4 @LP-Ag nanocatalyst. The fabricated nanocatalyst...
