A novel catalyst of MnFe 2 O 4 manganese ferrite nanoparticles (MFN) was synthesized by simple co-precipitation method and successfully used as an efficient heterogeneous photocatalyst following Langmuir-Hinshelwood kinetic approach for the rapid photocatalytic degradation of organic dyes such as Crystal Violet (CV). Several techniques like, Fourier transform infrared (FTIR), X-ray diffractometer (XRD), scanning electron microscope (SEM) and energy dispersive X-ray (EDX) were used to characterize the synthesized heterogeneous photocatalyst. The outcomes of the characterization established that the MNF can be competently synthesized with the size ranging between 20 to 50 nm, using sodium dodecyl sulphate (SDS) as stabilizer. UVvisible spectrophotometer was used for monitoring CV dye photodegradation. Different controlling analytical parameters such as dosage of MFN photocatalyst, concentration of CV dye, time and pH were optimized to explore the potential application of newly synthesized catalyst MFN for the maximum photodegradation of CV dye. The kinetics of reaction mechanism was also analyzed by plotting Eley-Rideal model and Langmuir-Hinshelwood model. The MFN was found to be an environmental friendly, highly economical and effective heterogeneous photocatalyst with rapid 90% efficiency to degrade the dye under investigation and easily could be regenerate with the help of magnet for successive uses.

“…Moreover, the ternary nanocomposite exhibits high catalytic stability in both MeOH and EG solutions. GPN is found to be a better inexpensive electrocatalyst in comparison to many other reported electrocatalysts; 11,[45][46][47] (1 g) have been dissolved in 50 ml of ethanol and stirred for 20 min and named as solution I; simultaneously, the oxalic acid (1.51 g) solution in 20 ml of ethanol, named as solution II has also been stirred for 20 min. After that, solution I and solution II have been mixed together and continuously stirred at room temperature and a homogeneous solution has been formed and then the mixture has been transferred to a Teflon-lined steel autoclave.…”

Present work reports the development of a mesoporous ternary nanohybrid (GPN) based on NiMn2O4, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and reduced graphene oxide (rGO) for methanol (MeOH) and ethylene glycol (EG) oxidation. Initially, NiMn2O4 nanoparticles have been synthesized using solvothermal-assisted calcination and then polymerization of EDOT monomer has been done in presence of rGO nanosheets and NiMn2O4 nanoparticles to form GPN nanohybrid. The current densities of 70.4 mA cm−2 at an onset potential of 0.21 V in 0.5 M MeOH and 53 mA cm−2 at an onset potential of 0.32 V in 0.5 M EG solution have been recorded at GPN modified indium tin oxide (ITO) electrode. This electrode exhibits a current retention of 87% in 0.5 M MeOH and 81% in 0.5 M EG solution after 700 cycles. The improved electrocatalytic activity and cyclic stability of GPN can be attributed to the presence of rich binary active sites of Ni and Mn species, large surface area and high electrical conductivity of rGO and uniform dispersion of NiMn2O4 nanoparticles over PEDOT:PSS. This work demonstrates the potential of GPN nanohybrid as an alternative to platinum towards MeOH and EG electro-oxidation.
