Semiconductor-to-metallic flipping in a ZnFe 2 O 4 –graphene based smart nano-system: Temperature/microwave magneto-dielectric spectroscopy

Synthesis, characterization and optical properties of in situ ZnFe2O4 functionalized rGO nano hybrids through modified solvothermal approach

“…Functionalized rGO-ZnFe 2 O 4 nano hybrids were synthesized using modified form of solvothermal synthesis using in situ precipitation of ZnFe 2 O 4 and reduction of graphene oxide, scheme of which is also reported elsewhere recently [31]. In a typical experiment, a certain amount of graphene oxide powder was mixed with another solution of zinc nitrate and iron nitrate in stoichiometric ratio in ethanol and DI water in a definite proportion.…”

Adsorption and photocatalytic degradation of gas-phase UDMH under simulated sunlight by AgBr/TiO2/rGA

“…The diffraction peaks at 10.9° in GO represent oxidized graphite corresponding to the (001) plane. 16 The d -spacing value of GO calculated using Bragg's law (2 d sin θ = nλ ) is 0.76 nm based on the (001) reflection plane. The wide diffraction peak at around 26.5° in rGA can be attributed to the high stripping of graphene.…”

Fabrication of magnetic and recyclable In2S3/ZnFe2O4 nanocomposites for visible light photocatalytic activity enhancement

“…Figure 3(B) describes the high resolution XPS spectrum of Fe 2p. Using the XPS Peak fitting program, the Fe 2p XPS region is fitted to two main peaks at 725.6 and 711.1 eV [30,31], which are attributed to Fe 2p 1/2 and Fe 2p 3/2 of Fe 3+ in nanocomposites, respectively. As seen from figure 3(C, the peaks at 1044.2 and 1020.9 eV could be assigned to Zn 2p 1/2 and Zn 2p 3/2 , respectively, indicating a normal state of Zn 2+ [23].…”
