Developing efficient and stable electrocatalysts with three-dimensional (3D) hierarchical nanostructures is extremely important in practical applications of direct alcohol fuel cells. Herein, 3D hierarchical thorn-like multi-metallic PtPdNiCu alloyed nanotripods (PtPdNiCu TNTPs) were efficiently fabricated by a one-pot aqueous method, in which Pluronic F127 performed as the structure-director and dispersing agent. The as-prepared PtPdNiCu TNTPs exhibited distinct electrocatalytic activity for methanol oxidation reaction (MOR) with a mass activity (MA) of 1.465 A mg, which is superior to commercial Pt/C (0.925 A mg) in 1.0 M KOH solution, along with the greater MA (1.019 A mg) for ethanol oxidation reaction (EOR) than Pt/C (0.712 A mg). This work would provide an impetus for rationally constructing multimetal nanomaterials to commercial implementation of advanced alcohol fuel cells.

TiO-based fibrous membranes as plasmonic heterojunction photocatalysts would hold great promise in the field of water disinfection, however, it still existed a great challenge to design and construct such materials. Here, we presented the fabrication of continuous, hierarchical, and easy-to-recycle flexible AgCO/TiO heterostructured nanofibrous membranes (NMs) that were composed of thorn-like nanofibers through electrospinning technique followed by successive ionic layer adsorption and reaction (SILAR) process. AgCO nanoplates were firmly anchored on the surface of TiO and the obtained AgCO/TiO heterojunction photocatalysts underwent a silent-to-active transition of visible-light response under light irradiation due to the surface plasmon resonance (SPR) effect of Ag nanoparticles derived from AgCO, forming a new plasmonic heterojunction photocatalyst.

The study focuses on facile shape-controlled deposition of rose, splintery, chrysanthemum flower, and thorn-like structures of palladium on indium-tin-oxide substrates. The hierarchical variation in morphologies from roses to thorns is attributed to a rational choice of the applied potential. This study involved investigating the influence of the precursor concentration, nature of the electrolyte, and deposition time on the morphological patterns.
