Facile formation of SnO2–TiO2 based photoanode and Fe3O4@rGO based counter electrode for efficient dye-sensitized solar cells

Matrix-dispersed magnetic molecularly-imprinted polyaniline for the effective removal of chlorpyrifos pesticide from contaminated water

“…In case of SPIONS, the diffraction peaks were perceived at 2q values of 30.1 (220), 35.5 (311), 43.2 (400), 53.5 (422), 57.1 (511) and 62.7 (440). 52,57 The same diffraction angles were obtained in case of MMIP but with a weaker intensity indicating the successful incorporation of SPIONs into the molecularly imprinted PANI matrix. Due to similarities in the XRD diffraction pattern of magnetite (Fe 3 O 4 ) and maghemite (g-Fe 3 O 4 ), they cannot be distinguished based on their X-ray diffractograms.…”

Tin oxide based nanostructured materials: synthesis and potential applications

“…Fig. 24 249 shows that the synthesized SnO 2 /TiO 2 nanocomposite showed excellent thermal stability with only 5% weight loss at 1073 K. The nanocomposite can replace platinum as a photoanode and it showed a power conversion efficiency of 3.28%. Also, due to the improved charge transfer, delayed recombination, and reduced band-gap, the DSSC showed enhanced efficiency.…”

“…Researchers worked on dye-sensitized solar cells and modified their photoanode using a SnO 2 /TiO 2 nanocomposite to alter the photovoltaic parameters. 249 The hydrothermal process was followed to synthesize the nanocomposite, and the photovoltaic parameters were measured using the current-voltage curve. Fig.…”

Highly improved solar cell efficiency of Mn‐doped amine groups‐functionalized magneticFe3O4@SiO2nanomaterial

“…Magnetic Fe 3 O 4 nanomaterials with good optical absorption show superior optoelectronic properties and high performance in solar cells due to the same number of divalent (Fe 2+ ) and trivalent ions (Fe 3+ ). 5 There are some difficulties in stabilizing magnetic Fe 3 O 4 nanomaterials and suppressing the reflection of light. Fe 3 O 4 can turn into Fe 2 O 3 with the effect of light.…”
