Fabrication of a porous Pd film on nanoporous stainless steel using galvanic replacement as a novel electrocatalyst/electrode design for glycerol oxidation

On the role of electrodeposited nanostructured Pd–Co alloy on Au for the electrocatalytic oxidation of glycerol in alkaline media

“…Recently, Rezaei et al successfully fabricated Pd/Cu/NPSS electrode using pulse electrodeposition of Cu on nanoporous stainless steel (NPSS) and afterward galvanic replacement between PdCl 2 and Cu. It was found that the Pd/Cu/NPSS electrode exhibited a remarkable improvement in the catalytic activity for glycerol electrooxidation in alkaline solution [23].…”

Pd-modified PEDOT layers obtained through electroless metal deposition—electrooxidation of glycerol

“…The data for the mass electroactivity (MA = j f /m Pd ) of the investigated Pd-PEDOT specimens are given in Table 1. In comparison to the mass electroactivity of other Pd-based electrocatalysts [13,16,17,25], tested at the comparable conditions, the value obtained here, j f /m Pd = 720 mA mg −1 , is markedly higher (Table 2). A similar value for MA is communicated for Pd NPs supported on carbon powder [12] whereas markedly higher values were obtained when using complex binary carbide and carbon aerogel composites as support for Pd [12].…”

“…It was found that electrooxidation of glycerol may be significantly enhanced by using electrochemically treated palladium surfaces [9]. Different ways of reducing the palladium content and increasing the electroactive surface area were explored such as galvanic replacement of electrochemically deposited copper by palladium [13], formation of two-dimensional assemblies of Pd NPs [14], or use of Pddecorated core-shell nanocatalysts [16]. Further improvements in terms of electrocatalytic activity were sought by combining Pd with other metals, e.g., Au and Ni [7] or adatoms of Sb, Pb, and Sn [15].…”

“…Much effort is put into the development of various Pd-based electrocatalytic materials [5][6][7][8][9][10][11][12][13][14][15][16][17][18] due to the prospect to reduce the platinum content in fuel cells. Comparative studies of Pt-and Pd-supported nanoparticles (NPs) have shown that the onset potential for glycerol oxidation is lower on Ptbased catalysts, but nevertheless, in specific experimental conditions, higher oxidation currents are observed on Pd-based materials [8,10].…”

Controllable fabrication and temperature-resistance characteristics of ordered nanoporous Au and Pt films

“…For the fabrication of the porous novel metal nanostructure, various methods, such as template-based, heat treatment of electrospun nanofibers, electrochemical and dealloying are currently used to obtain the porous novel metal nanostructure [16][17][18][19][20][21]. However, these studies focus on nanoporous novel metal particles or hollow spheres.…”
