Morphology-controlled synthesis of 3D flower-like NiWO4 microstructure via surfactant-free wet chemical method

A Core‐Shell Assembly of Hierarchical Porous Ni@C Nanospheres Synthesized from Metal‐Organic Framework for Electrochemical Energy Application

“…The XPS spectrum of Ni 2p in Figure c reveals zero‐valent metallic states of Ni in HP‐Ni@C‐N material similar to the highlighted in Figure a XRD and Figure f HRTEM results. The binding energy of 852.9 eV corresponds to the zero valent metallic nickel (Ni 0 ), while the peak at 855.7 eV can be assigned to Ni 2+ . The occurrence of Ni 2+ indicating partial surface oxidation of Ni NPs following exposure to atmosphere, suggesting that a few nickel particles are not fully wrapped within the layers of carbon.…”

Co–N–C catalysts derived from folic acid and mediated by hydrazine hydrate for selective hydrogenation of quinoline

“…14 To solve this problem, we employed hydrazine hydrate to promote the dissolution of FA and make it complex with Co 2+ , and found that the amount of hydrazine hydrate could also regulate the pore structure and Co distribution of the pyrolysis catalysts. 15–17 The experimental results and characterization indicated that the above catalysts showed remarkable hydrogenation activity for quinoline. Furthermore, the substrate scope and active sites of the catalyst were also explored.…”

N-Doped ZnWO4 Nanorods Decorated on N-Doped Reduced Graphene Oxide Sheets for Electrochemical Detection of Diphenylamine

“…To date, a variety of methods, such as hydrothermal (HT), − sonochemical, ultrasonic-assisted coprecipitation, solid-state, microwave-hydrothermal, coprecipitation, , sol–gel, solvothermal, microwave, mechanochemical, solution combustion, microemulsion, and wet chemical method, have been successfully reported. However, these methods, except for HT, require severe reaction conditions such as a high temperature, surfactants, complicated procedures, a long reaction time, and difficulties in large-scale synthesis.…”
