Synergistic Roles of the CoO/Co Heterostructure and Pt Single Atoms for High-Efficiency Electrocatalytic Hydrogenation of Lignin-Derived Bio-Oils
Electrochemical
hydrogeneration (ECH) of biomass-derived platform
molecules, which avoids the disadvantages in utilizing fossil fuel
and gaseous hydrogen, is a promising route toward value-added chemicals
production. Herein, we reported a CoO/Co heterostructure-supported
Pt single atoms electrocatalyst (Pt1-CoO/Co) that exhibited
an outstanding performance with a high conversion (>99%), a high
Faradaic
efficiency (87.6%), and robust stability (24 recyclability) at −20
mA/cm2 for electrochemical phenol hydrogenation to high-valued
KA oil (a mixture of cyclohexanol and cyclohexanone). Experimental
results and the density functional theory calculations demonstrated
that Pt1-CoO/Co presented strong adsorption of phenol and
hydrogen on the catalyst surface simultaneously, which was conducive
to the transfer of the adsorbed hydrogen generated on the single atom
Pt sites to activated phenol, and then, ECH of phenol with high performance
was achieved instead of the direct hydrogen evolution reaction. This
work described that the multicomponent synergistic single atom catalysts
could effectively accelerate the ECH of phenol, which could help the
achievement of large-scale biomass upgrading
