This study focuses on enhancing the photoelectrocatalytic (PEC) performance of LaFeO3 photocathodes by incorporating Ag nanocrystals. LaFeO3, a perovskite-type metal oxide semiconductor, has potential in PEC water splitting but suffers from fast charge carrier recombination. nanoparticles are introduced due to their surface plasmon resonance (SPR) property and ability form Schottky junctions with LaFeO3. A series Ag/LaFeO3 materials prepared using molten salt method for synthesis direct reduction loading. The results show that uniformly dispersed 3 mol% photocathode demonstrates remarkable ninefold increase photocurrent density (15 mA·cm−2 at −0.2 V vs. RHE) compared pure (1.7 mA·cm−2). band gap is reduced 2.07 eV 1.92 loading, transfer impedance 77%, while concentration increases 2.3 times. novelty this work lies comprehensive investigation interaction mechanisms between which lead enhanced light absorption, improved separation, increased electrochemical activity. optimized loading not only improves photocatalytic efficiency also enhances stability photocathode. provides valuable insights into offers experimental theoretical support developing efficient splitting.

The citrate gel method was used to prepare nanostructured ferrites having composition Co1-yMnyYbxFe2-xO4 (x = y 0.00, 0.02, 0.04, 0.06, 0.08 and 0.1) nanoferrites investigated their structural, magnetic, catalytic antibacterial activities. A cubic spinel structure with crystallite diameters between 16.77 nm 34.84 established by X-ray diffraction (XRD), while granular morphology elemental were disclosed scanning electron microscopy (SEM) energy-dispersive spectroscopy (EDS). Molecular vibrations described Fourier-transform infrared (FTIR) Raman spectroscopy, which verified the production of structures. Vibrating sample magnetometry (VSM) revealed that doping doses caused considerable changes in magnetic anisotropy varying characteristics like coercivity saturation magnetization. Methylene blue rhodamine dyes investigate photocatalytic activity these YMN-5 showed best degradation efficiency. Moreover optimal doping, antimicrobial against a variety pathogens increased These results demonstrate potentiality Yb-doped Mn-Co biomedical applications environmental remediation.
