Shape-dependence in seeded-growth of Pd-Cu solid solution from Pd nanostructure towards methanol oxidation electrocatalyst

Confined Growth of Palladium Nanoparticles on Nanographdiyne: A Model Study of Bulk Graphdiyne–Metal Covalent Interaction

“…Besides, the peak current ratio of the positive scan (I f ) to negative scan (I b ), I f /I b , represents the ability to tolerate the poisoning of carbonaceous species. The 200Pd/ 1 shows an I f /I b of 2.8, which is higher than those of Pd 1 Cu 1 (0.8), Au@Pt 1 –Pd 1 H-Ss (1.1), Pd-UNs/Cl-GDY (1.8) 50 , PdAgSn/PtBi HEA NPs (1.9), and Pd(20%)-CeO 2 (20%)/NMCS (2.3), implying a good methanol tolerance and sufficient active sites for methanol adsorption and conversion. The CO stripping tests were also conducted to evaluate the poisoning tolerance of the catalysts.…”

Hierarchical PdNi alloy nanochains coupled with Ni(OH)2 nanosheets to enhance CO-poisoning resistance for the methanol oxidation reaction

“…[24][25][26][27] Doping foreign metals into Pd nanocrystals could not only reduce the dosage of Pd, but also be effective at inducing synergistic effects for accelerating the MOR kinetics. 6,28,29 Among foreign metals, Ni and its compounds have been considered the most promising ones because of their cost effectiveness, abundance in nature, and versatile oxidation states. [30][31][32][33] Currently, the regulation mechanism of Ni could be classified into two types.…”
