A Novel Approach for the Preparation of Carbon Supported Intermetallic Cu<sub>3</sub>sn Nanoparticles and Their Electrocatalytic Performance for CO<sub>2</sub> Reduction
Abstract
<jats:p>Carbon supported ordered intermetallic Cu<jats:sub>3</jats:sub>Sn nanoparticles (NPs), which had a Cu<jats:sub>3</jats:sub>Ti type structure (1), was successfully prepared through a wet-chemical method (2) using lithium triethylborohydride as reducing agent. The prepared ordered intermetallic Cu<jats:sub>3</jats:sub>Sn was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and transmission electronic microscope (TEM). Cu<jats:sub>3</jats:sub>Sn intermetallic structure not only showed a higher electrocatalytic activity towards CO<jats:sub>2</jats:sub> electrochemical reduction, but also selectively converted CO<jats:sub>2</jats:sub>to CO, compared with pure Cu NPs. </jats:p><jats:p>Figure 1 allows us to confirm the crystal structure of intermetallic Cu<jats:sub>3</jats:sub>Sn, disordered Cu-Sn alloy and pure Cu NPs, respectively. The main diffraction peaks of Cu NPs and disordered Cu-Sn alloy can be observed which are assigned as FCC-type structure while the XRD pattern of intermetallic NPs shows a good fit with stoichiometric Cu<jats:sub>3</jats:sub>Sn structure based on Cu<jats:sub>3</jats:sub>Ti-type lattice (1). Figure 2 shows the Faradaic efficiency (FE) for gaseous products which was evaluated in CO<jats:sub>2</jats:sub> reduction for intermetallic Cu<jats:sub>3</jats:sub>Sn under the potential varying from -0.8 V to -1.6 V <jats:italic>vs.</jats:italic>RHE. It is suggested that the FE of CO production reaches the highest value of 40 % at -1.4 V, while the FE of hydrogen production is suppressed under 17%. </jats:p><jats:p>[1] Y.
