Special Magnetic Catalyst with Lignin-Reduced Au-Pd Nanoalloy.

ABSTRACT: This study describes a new strategy to fabricate a special magnetic catalyst via facile coating Au-Pd nanoalloy catalysts onto a commercial magnetic stirring bar, without the incorporation of iron element. First, the abundant natural "waste" lignin was utilized as the reducing and stabilizing agent to prepare Au-Pd nanoalloys in a green manner. The Au-Pd nanoalloys were assumed to have a core-shell structure with an Au-rich core and a Pd-rich shell. The Au-Pd nanoalloys could be well dispersed in aqueous medium due to the stabilizing effect of lignin and be conveniently coated onto the surface of a commercial stirring bar. The Au_1.0Pd_1.0 nanoalloy catalyst exhibited excellent catalytic activities in the reduction of 4-nitrophenol to 4-amnophenol by NaBH₄, w
