New development and photocatalytic performance and antimicrobial activity of α-NH4(VO2)(HPO4) nanosheets

α-NH₄(VO₂)(HPO₄) nanosheets were developed by hydrothermal method. Furthermore, it's determined by the several analyses like XRD, Raman, FESEM, TEM, UV-Visible spectroscopy, TGA and DRS UV-Visible spectroscopy studies. The orthorhombic crystalline phase of α-NH₄(VO₂)(HPO₄) nanosheets were recognized by XRD analysis. The α-NH₄(VO₂)(HPO₄) nanosheets functional groups identification was investigated by Raman spectroscopy. Thermal gravimetric analysis of α-NH₄(VO₂)(HPO₄) nanosheets were identified and its attain for three decomposition stages. The nanosheets of the α-NH₄(VO₂)(HPO₄) was clearly evaluated by FESEM and TEM measurements. α-NH₄(VO₂)(HPO₄) nanomaterial band gap energy was determined by DRS UV Visible spectroscopy analysis and the calculated bandgap energy is 1.83 eV. Hence, it was more convenient way for the dye degradation applications. These α-NH₄(VO₂)(HPO₄) nanosheets was will be tested in the photocatalytic and antimicrobial applications. In this case, antimicrobial study was not encouraged in the catalyst. Consequently, this material has more encouraging for electrostatic interaction with enhanced for the applications.

Global popularization of CuNiO2 and their rGO nanocomposite loveabled to the photocatalytic properties of methylene blue

New advancements of photocatalytic activity with higher efficiency, low price are most important, which is challenging in industrialized and many fields. We have introduced CuNiO₂ and CuNiO₂/rGO nanocomposite was generally prepared by the hydrothermal treatment and tested to the photocatalytic studies. Photocatalytic measurements of CuNiO₂ with different weight percentages CuNiO₂/rGO (25/75), (50/50), and (75/25) are achieved to the efficiency under visible light, in this case, CuNiO₂/rGO (50/50) composite have the highest performance is scrutinized. This was obeyed for a synergistic effect between CuNiO₂ nanoparticles and rGO composites. Furthermore, the CuNiO₂, CuNiO₂/rGO (25/75), (50/50), and (75/25) nanocomposite were tested by several analyses like XRD, FT-IR, DRS UV Visible spectroscopy, Raman spectroscopy, and FESEM & HRTEM investigations. In this regard all measurements are very clear and satisfied; therefore we are encouraged for future developing environmental applications.
