Promotion of PdCu/C Catalysts for Ethanol Oxidation in Alkaline Solution by SnO2 Modifier

Abstract: The development of high performance PdCu/C catalysts through manipulation of reduction temperatures and addition of SnO2 promoter has been elucidated systematically in order to enhance ethanol oxidation reaction (EOR) performance. The structure, morphology, surface species, and electroactivity of the PdCu/C and SnO2‐modified PdCu/C catalysts are characterized by use of X‐ray diffraction, high resolution transmission electron microscopy, X‐ray photoelectron spectroscopy, and cyclic voltammetry. For the PdCu/C c… Show more

“…However, tin oxide has problems related to its poor selectivity towards various gases. In general, suitable catalysts, noble metals, and transition metals are inserted into SnO 2 sensors to improve their selectivity and sensing response [ 6 , 7 , 8 ]. These metals’ catalytic activities, coupled with the semiconductor properties of the materials used, have resulted in their applications for detection of organic, inorganic vapors, and other toxic, inflammable or hazardous gases [ 9 , 10 ].…”

“…172 However, the addition of excess Sn may lead to the formation of a large amount of SnO 2 on the catalyst surface, blocking the active sites of the catalyst and thus reducing the EOR performance. 173 As to the HER, adding Sn into MoS 2 has a twofold effect. Sn, as a type II co-catalyst, can create additional active sites in MoS 2 .…”

“…The porosity and orderliness significantly improved the specific surface area, electron transport capabilities, and active site density of SnO 2 nanomaterials. In addition, suitable noble metals and transition metals are inserted into SnO 2 sensors; these metals’ activities coupled with the semiconductor properties could improve their selectivity and sensing response. …”
