Engineering Heterostructured Pd–Bi2Te3 Doughnut/Pd Hollow Nanospheres for Ethylene Glycol Electrooxidation

“…As observed in Figure d, the I f / I b of Pd–Bi 2 Te 3 -1/C is calculated to be about 2.76, which is much higher than those of Bi 2 Te 3 /C (1.51) and Pd/C (1.55), confirming the higher electrocatalytic activity of the Pd–Bi 2 Te 3 -1/C catalyst. More importantly, the electrocatalytic EGOR activity of Pd–Bi 2 Te 3 is also much better than those of the recently reported Pd-based electrocatalysts (Figure e). − In order to evaluate the reaction kinetics of the EGOR based on different electrodes, the Tafel plots of different electrocatalysts are also achieved. As shown in Figure a, Pd–Bi 2 Te 3 -1/C showed a Tafel slope of 138.4 mV dec –1 , which was smaller than those of Bi 2 Te 3 /C (325.0 mV dec –1 ) and Pd/C (196.5 mV dec –1 ), suggesting better reaction kinetics based on the Pd–Bi 2 Te 3 -1/C electrocatalyst.…”

Recent developments in electrode materials for the selective upgrade of biomass-derived platform molecules into high-value-added chemicals and fuels

“…The composite catalysts formed by non-Pt noble metals and transition metals are also considered advanced materials, which not only reduced the cost of improving the utilization efficiency of noble metals but also effectively adjusted the morphology and activity of catalysts. 153,177,[201][202][203][204] By introducing hexadecyltrimethylammonium bromide (CTAB) into the reaction system, Xu et al successfully prepared binary Pd 2 Pb alloy nanocubes (Pd 2 Pb NCs) with outstanding properties and synergistic effects, which showed excellent catalytic activity and stability in the GOR. 205 Metal oxides also act as a kind of promising catalyst component, which has great potential for electron injection/extraction at the electrodes.…”

Porous Noble Metal Electrocatalysts: Synthesis, Performance, and Development

“…Growth units with the specific structure and capping agents adsorbed on specific crystal face determine the growth direction and assembly behavior of noble metals (Table 3). The surfactants (such as oleic and oleylamine) [91][92][93] often act as protective agents to inhibit the excessive aggregation and fusion of the synthesized nanoparticles. Growth units with different structure influenced by ligands would take diverse nucleation path.…”

“…Gelation process in traditional synthesis would take a long time (several days). On the premise of ensuring the quality and maintaining 3D spatial network structure and large PdPb [93] Pd(acac) 2 a)…”
