Pd coated one-dimensional Ag nanostructures: Controllable architecture and their electrocatalytic performance for ethanol oxidation in alkaline media

Novel and High Electrocatalytic Activity Aerogel Pd-Tm (Tm=Co, Ni, Fe)

“…BET surface areas of Pd aerogels should be in the range of 32e162 m 2 /g, the density in the range of 0.10e12 g/cm 3 and the pore size <50 nm according to the bibliography [6,19,20]. In fact, the surface area of the Pd aerogel is referenced as 50 m 2 /g and the pore size of about 11 nm [20].…”

Effect of Anode Material on Electrochemical Oxidation of Low Molecular Weight Alcohols—A Review

“…Doping with silver leads to electrocatalytic materials that are more active and more stable towards the EOR in alkaline environments [ 26 , 136 , 153 , 154 ]. The addition of silver to a palladium catalyst leads to a lower potential of the reaction peak than pure Pd under the same conditions, which may contribute to the acceleration of the reaction rate and the smaller size of the obtained catalytic particles, leading to a larger electroactive surface on the working electrode [ 26 , 136 , 153 , 154 ]. To obtain a larger electroactive surface on such electrodes, different core–shell structures, such as PdAg@Pd core–shell worm-like structures, which are shown in Figure 2 , have been developed [ 26 ].…”

“…To obtain a larger electroactive surface on such electrodes, different core–shell structures, such as PdAg@Pd core–shell worm-like structures, which are shown in Figure 2 , have been developed [ 26 ]. Because of its structural properties, this type of nanomaterials has shown better stability and higher residual activity and better noble-metal utilization than other catalysts [ 26 , 136 , 153 , 154 ].…”

Simple Synthesis of PdAg Porous Nanowires as Effective Catalysts for Polyol Oxidation Reaction

“…It has been confirmed that the electrocatalysis of Pd-based catalysts for EGOR and GOR can be optimized by adjusting the morphology of catalysts. − The catalytic properties of hollow, spherical, tubular, sheet, and gridlike Pd-based nanomaterials for EGOR and GOR have been reported and studied. − Among them, Pd-based hollow catalysts have been widely studied benefiting from the geometric effect of the hollow structure. Pd-based nanomaterials exhibit excellent catalytic performance because their hollow structures utilize large internal void spaces and surface pores to optimize the specific surface area and increase their active sites. , Pd-based catalysts can also increase their surface area by increasing their surface roughness, thereby further improving their catalytic performance. At the same time, one-dimensional nanostructures have also received widespread attention because they can optimize the stability and catalytic activity of catalysts and improve the conductivity of catalysts. − Therefore, porous nanowires with irregular surfaces may exert excellent performance for EGOR and GOR …”
