Abstract

This work describes the use of urea as fuel and a simple solution-based approach technique for both the pure and Ce-doped ZnMn2O4. The magnetic, structural, optical, morphological, vibrational spectroscopy and solar cell analysis were performed on the resultant materials. By increasing the Ce doping, the grain size shrank. On the other hand, the average crystallite size of pure and Ce-doped ZnMn2O4 represents 29–21 nm. The results of vibrational spectroscopy revealed that the absorption bands 450–900 cm−1 and 950–1050 cm−1 both exhibit spinal manganite formation. The morphologies of the highly uniformly distributed nanoparticles in each sample varied according to the preparation. To reach the Ce doping level, the band gap energy (1.4–2.2 eV) was lowered from the bulk to the nanoscale. M-H loops, the composites showed that cations were paramagnetic to ferromagnetic, were occupied by octahedral and tetrahedral structures. Additionally, the impact of doping on the optical and structural characteristics of various blends was investigated. This advancement suggests the application of prepared blends in various optoelectronic, electrochemical, storage devices, and solar cell applications. [ABSTRACT FROM AUTHOR]

Abstract

Specifically, biocatalyst coupled semiconductor photocatalysts have great potential towards the eco-friendly decomposition of toxic organic dyes that contaminate water bodies. This study reports the synthesis of vermiwash activated molybdenum doped tin oxide (Mo:SnO2) nanomaterial, for the photocatalytic degradation of a representative cationic dye - methylene blue (MB). The photocatalytic performance of the synthesized nanoparticles was evaluated using UV-visible (UV-vis) spectroscopy and the degrading efficiency of MB dye was quantified. The addition of vermiwash resulted in a marked improvement in the photocatalytic activity of Mo:SnO2 nanoparticles, with a degradation efficiency of 96% achieved after 75 min of irradiation. The nanoparticles were characterized using XRD, SEM-EDX, TEM, FTIR, XPS and UV-vis to confirm the crystal structure, morphology, functional groups, elemental analysis and bandgap energy by using Tauc's plot. The study demonstrates the potential of vermiwash as a green and efficient bio co-catalyst for improving the photocatalytic activity of Mo:SnO2 nanoparticles regarding the degradation of textile effluents. Thus, this study paves a way for new eco-friendly approach for the synthesis of cost-effective, biocatalyst coupled semiconductor photocatalyst. [ABSTRACT FROM AUTHOR]
