Heterostructured Ru/Ni(OH)<sub>2</sub> Nanomaterials as Multifunctional Electrocatalysts for Selective Reforming of Ethanol
The
electrochemical reforming of ethanol into hydrogen and hydrocarbons
can reduce the electric potential energy barrier of hydrogen production
from electrochemical water splitting, obtaining high value-added anode
products. In this work, Ru/Ni(OH)2 heterostructured nanomaterials
were synthesized successfully by an in situ reduction
strategy with remarkable multifunctional catalytic properties. In
the hydrogen evolution reaction, Ru/Ni(OH)2 exhibits a
smaller overpotential of 31 mV to obtain a current density of 10 mA/cm2, which is better than that of commercial Pt/C. Notably, such
heterostructured Ru/Ni(OH)2 nanomaterials also perform
an outstanding catalytic selectivity toward an acetaldehyde product
in the oxidation of ethanol. DFT calculations reveal that abundant
Ru(0)-Ni(II) heterostructured sites are the key factor for the excellent
performances. As a result, an ethanol-selective reforming electrolyzer
driven by a 2 V solar cell is constructed to produce hydrogen and
acetaldehyde in the cathodic and anodic part, respectively, via using
Ru/Ni(OH)2 heterostructured catalysts. This work provides
a forward-looking technical guidance for the design of novel energy
conversion systems
