Fabrication of nanoporous palladium by dealloying and its thermal coarsening

Nanoporous nickel-copper-phosphorus amorphous alloy film for methanol electro-oxidation in alkaline medium

“…Notably, there have been many studies on nanoporous single-element materials, such as nanoporous Pt [32], Pd [33], Cu [34], Au [35,36], Ag [37], Ni [38][39][40], which showed higher methanol catalytic performances as compared with the bulk materials. The nanoporous materials were generally formed by dealloying method, in which the less noble component A in a binary A x B 1-x or multicomponent alloy is selectively removed by chemically or electrochemically [41].…”

Solid/electrolyte interface phenomena during anodic polarization of Pd0.2M0.8 (M=Fe, Co, Ni) alloys in H2SO4

“…The fabrication of nanoporous Au from Au-Ag alloy and its properties have been surveyed very frequently [1][2][3][4][5]. Other nanoporous metals such as Cu [6], Ni [7,8], Pt [9,10] and Pd [11][12][13] can also be fabricated from proper initial binary alloys.…”

“…Nanoporous Pd can be readily fabricated by the dealloying of Pd-Co alloy in H 2 SO 4 under a suitable electrochemical potential [12,13]. Pd-Fe and Pd-Ni are other possible initial binary alloys for nanoporous Pd because standard electrode potentials of Fe and Ni as well as that of Co are sufficiently lower than that of Pd [14].…”

Preparation of nanoporous Ni and Ni–Cu by dealloying of rolled Ni–Mn and Ni–Cu–Mn alloys

“…Other metals can also be made nanoporous through dealloying; for example, Pugh et al [8] and Liu et al [9] fabricated nanoporous platinum by dealloying Pt-Cu alloy. Nanoporous Pd can also be fabricated by dealloying of Pd-Co [10,11] and amorphous Pd-Ni-P alloys [12].…”
