Electrocatalytic reduction of furfural with high selectivity to furfuryl alcohol using AgPd alloy nanoparticles

“…10 Similar effects have been observed in recent reports where AgPd nanoalloys were used as catalysts in different electrochemical systems. 11,12 The results herein demonstrate that bimetallic AgPd alloy nano-Scheme 1 Summary of furfural production and common electrochemical reduction products derived from furfural.…”

PdAg/Ag(111) Surface Alloys: A Highly Efficient Catalyst of Oxygen Reduction Reaction

“…In this case, the ORR can reach high catalytic performance. Unlike several existing experimental studies on the ORR reactions of PdAg clusters or thin-film alloys [ 24 , 62 , 66 , 67 ], here, we simulated a model of SAA with a special inner-layer structure which has been prepared by heat treatment combined with quenching in our previous experiments. As can be seen from Figure 5 , all the structures had higher limiting potentials than pure Ag(111) ( = 0.61 V), and Pd M @Pd 1L Ag(111) and Pd D @Ag(111) were higher than pure Pd(111) ( = 0.79 V), indicating a synergistic enhancement between Pd and Ag, which can provide solution ideas for the design of bimetallic catalysts.…”

Electronic and Potential Synergistic Effects of Surface-Doped P–O Species on Uniform Pd Nanospheres: Breaking the Linear Scaling Relationship toward Electrochemical Oxygen Reduction

“…2,8,12,21 However, Pd still possesses an unsatisfactory ORR electrocatalytic performance compared to Pt especially under acidic conditions. Therefore, several effective methods have been developed for increasing the surface active sites and particularly enhancing the intrinsic activity: (1) optimizing sizes and distributions, 22,23 (2) alloying with foreign elements, 23−39 (3) fabricating unique nanostructures, 25,26,[28][29][30][31][33][34][35]37,40,41 (4) regulating surface crystal structures, 23,24,27,29,32,34,35,38,40−42 and (5) utilizing proper supports, 22,43 and so on. The conventional optimizing strategy is to weaken the too-strong adsorptions of the oxygencontaining intermediates on Pd during the ORR.…”

“…As the most practical and active ORR electrocatalysts at present, Pt-based nanomaterials have attracted enormous attention and been greatly investigated. ,,,, Nevertheless, the limited resources and the high prices have severely hindered the large-scale applications of Pt-based electrocatalysts. ,,,, Fortunately, Pd ranks only second to Pt as the best single-metal ORR electrocatalyst and also has a ∼200-fold higher reserve in the earth crust, making it a promising alternative. ,,, However, Pd still possesses an unsatisfactory ORR electrocatalytic performance compared to Pt especially under acidic conditions.
