Hematite nanoparticle-templated hollow carbon nanonets supported palladium nanoparticles: preparation and application as efficient recyclable catalysts

CoWO4 nanoparticles prepared by two methods displaying different structures and supercapacitive performances

“…For example, oxides of Ru [13], Ni [14], Co [15], Mn [16], Fe [17], Mo [18], V [19], and so forth have been explored, but some problems have still been existed for these single metal oxides, including the high cost, toxicity, low SC and cycling lifetime. Interestingly, mixed metal oxides [20] and binary metal oxides [21] have been reported to exhibit higher performance than single metal oxides because of their feasible oxidation states [22] and high electrical conductivity [23], so they seems to be the promising materials for supercapacitors.…”

An electron-rich free-standing carbon@Au core–shell nanofiber network as a highly active and recyclable catalyst for the reduction of 4-nitrophenol

“…Noble metal nanoparticles have attracted immense research interest in recent years because of their unique physical and chemical properties, and remarkable potential for extensive applications in electronic or optical materials, as well as in catalysis. [1][2][3][4][5] Gold nanoparticles (Au NPs) have attracted considerable interest for a variety of catalytic reactions recently. [6][7][8] In general, the high surface-to-volume ratio endows Au NPs with active performances for the chemical reactions.…”

Assembly immobilized palladium(0) on carboxymethylcellulose/Fe3O4 hybrid: An efficient tailor‐made magnetically catalyst for the Suzuki–Miyaura couplings

“…It could also be found that the existence of two intense doublets at 335.38 and 340.58 eV related to Pd(0) and peaks at 337.78 and 342.98 eV related to Pd(II) corresponding to Pd 3d 5/2 and Pd 3d 3/2 in the fresh catalyst respectively, which indicates that about 64% of palladium particles exist in the form of Pd(0). Nevertheless, only strong peaks at 335.28 eV and 340.68 eV corresponding to Pd 3d 5/2 and Pd 3d 3/2 can be seen in the reused catalyst, which shows the main existence of Pd NPs after the reaction …”
