Abstract:
The current work describes the synthesis of a
new bio-waste derived cellulosic-carbon supportedpalladium nanoparticles enriched magnetic nanocatalyst
(Pd/Fe3O4@C) using a simple multi-step process under
aerobic conditions. Under mild reaction conditions, the
Pd/Fe3O4@C magnetic nanocatalyst demonstrated excellent catalytic activity in the Hiyama cross-coupling
reaction for a variety of substrates. Also, the Pd/Fe3O4@C
magnetic nanocatalyst exhibited excellent catalytic activity
up to five recycles without significant catalytic activity loss
in the Hiyama cross-coupling reaction. Also, we explored
the use of Pd/Fe3O4@C magnetic nanocatalyst as an
electrocatalyst for hydrogen evolution reaction. Interestingly, the Pd/Fe3O4@C magnetic nanocatalyst exhibited
better electrochemical activity compared to bare carbon
and magnetite (Fe3O4
nanoparticles) with an overpotential
of 293 mV at a current density of 10 mA·cm–2
