In this paper, we report the successful synthesis of flowerlike Ni–NiO composite microstructures with room-temperature magnetism via a simple water–DMF (N,N-dimethylformamide) mixed solvothermal process with sequential thermal treatment, using sodium hypophosphite hydrate (NaH2PO2·H2O) and nickel sulfate (NiSO4·6H2O) as the starting reactants. The phase and morphology of the as-prepared product are characterized by means of powder X-ray diffraction, energy dispersive spectrometry, selected area electron diffraction (SAED), transmission electron microscopy, and scanning electron microscopy. Experiments show that the flowerlike Ni–NiO composite microstructures are obtained by the shape-preserved conversion of the precursor. Our investigation reveals that the as-prepared flowerlike Ni–NiO composite microstructures exhibit good electrochemical responses in 1 M NaOH solution and can be used as an electrochemical catalyst for the oxidation of methanol. Also, the as-prepared flowerlike Ni–NiO composite microstructures have a stronger catalytic activity for the chemical reduction of 4-nitrophenol to 4-aminophenol by NaBH4 than pure Ni nanospheres or flowerlike NiO microstructures.

Journal of Materials Chemistry A

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
