The supported PdSn-NW and PdL/PdSn-NW catalysts are supported on TiO2. The two-step protocol involving an annealing process was used for the synthesis of PdL/PdSn-NW. PdSn nanowire (NW) was prepared with a Pd: Sn molar ratio of 4 firstly and then, Pd precursor was deposited on the as-prepared PdSn nanowires again, followed by depositing on TiO2 and a rapid annealing in air. A PdSn-NW catalyst with Pd:Sn ratio of 4 was also synthesized for the purpose of comparison via one-step method by mixing Sn2+, Pd2+, PVP, EG, and NH4Br.
