Compared with the single metal, multi-metallic nanoparticles (NPs) have excellent localized surface plasmon resonance (LSPR) a wide spectral range response, which is beneficial to improve photoinduced electron transfer efficiency and promote effective electron-hole separation. In this paper, urchin-like Au-Ag-Pt-Pd nanoalloys (Au-Ag-Pt-Pd NUs) multiple tentacles were successfully synthesized by...

A low-cost efficient electrocatalyst for both oxygen reduction reaction (ORR) and evolution (OER) is urgently required the commercialization of Zn-air batteries. Herein, CoMn nanoalloys encapsulated in nitrogen-doped hollow carbon architectures (CoMn@NHC) as dual electrocatalysts batteries were developed successfully. The obtained CoMn@NHC nanohybrid expresses excellent electrocatalytic perform...

Electrical discharges in liquids are considered an efficient and ecological technique of nanoparticle synthesis via controlled erosion electrodes. Herein, we use spark between Co–Co, Ni–Ni, Co–Ni, or Ni–Co electrodes immersed distilled water to synthesize Co and/or Ni nanoparticles, as well their oxides. When mixed used (Co–Ni Ni–Co), both nanoparticles produced, the major species is dictated b...

Cu-based bimetallic materials have been widely reported as efficient catalysts for electrocatalytic nitrate reduction. However, the faradaic efficiency and selectivity are still far from satisfactory. Herein, Cu-Fe nanoalloys with adjustable Cu/Fe ratios successfully prepared through a reactive mechanical milling approach CuCl2, FeCl3 Na starting materials. The optimized Cu3Fe exhibits excellen...

Currently, FeNi nanoalloys have received considerable attention for the oxygen reduction reaction (ORR) and evolution (OER) in rechargeable aqueous zinc (Zn)-air batteries (ZABs) because of their high content good chemical stability. However, poor electronic conductivity, small surface area, sluggish activity seriously hinder catalytic performance. Herein, S-modulated supported by hierarchicall...
