Electro-oxidation of mixed reactants of ethanol and formate on Pd/C in alkaline fuel cells

Synthesis of Bimetallic PdAg Nanoparticles and Their Electrocatalytic Activity toward Ethanol

“…Direct ethanol fuel cells (DEFCs), with many outstanding virtues, such as low toxicity, renewable capability, and low environmental pollutant emission, have been extensively studied as an ideal alternative for the energy source [1][2][3][4][5][6][7][8][9][10]. At present, the application of DEFCs in the commercial level is still limited on account of their low catalytic activity and high price of catalysts, as well as poor stability.…”

Polyethyleneimine modified AuPd@PdAu alloy nanocrystals as advanced electrocatalysts towards the oxygen reduction reaction

“…Among them, bimetallic Pd-Au nanocrystals generally display the improved durability towards the alcohol molecules oxidation reaction and ORR because Au can effectively restrain the electrochemical dissolution of Pd. Meanwhile, bimetallic Pd-Au nanocrystals also exhibit improved ORR activity compared to monometallic Pd nanocrystals due to electronic and geometric effects [22][23][24][25][26] .Unfortunately, bimetallic Pd-Au nanocrystals lack the alcohol tolerance towards the ORR due to high catalytic activity towards the alcohol molecules oxidation reaction in the alkaline electrolyte [27][28][29][30][31][32] .…”

Advances in efficient electrocatalysts based on layered double hydroxides and their derivatives

“…Noble metal based electrocatalysts (such as Pt, Pd, and Ru) [52][53][54][55][56][57][58][59] have been demonstrated with superior behavior in various electrocatalytic reactions; however, they cannot afford wide range commercial application due to their scarcity and exorbitant price. To overcome this issue, tremendous endeavor has been devoted to non-precious candidates with low cost and high activity.…”
