Recent advancements in nanoscience underscore the transformative potential of nanomaterials environmental and biological applications. In this study, we synthesized gold nanoparticles (Au@TPE NPs) using an eco-friendly cost-effective approach, leveraging tangerine peel extract as both a capping reducing agent. This method presents sustainable alternative to traditional chemical agents. We optimized synthesis parameters, including time (5, 30, 60, 90 min), temperature (25, 40, 60°C), concentration 10, 15, 20 mM) refine size morphology. Characterization via UV-Vis, XRD, FT-IR, EDAX, FESEM, TEM revealed that at 40°C 15 mM exhibited optimal (∼26±5 nm) spherical shape. The Au@TPE NPs demonstrated antibacterial activity against Gram-positive Gram-negative bacteria, with minimum inhibitory concentrations (MIC) 31.25 μg/ml for Klebsiella pneumoniae Escherichia coli, 62.5 Pseudomonas aeruginosa. Notably, they also antifungal Candida albicans 92.7% antioxidant DPPH scavenging assay 250 μg/ml.

Replacing the oxygen evolution reaction (OER) in photoelectrocatalytic (PEC) water splitting with glycerol oxidation (GOR) not only enhances hydrogen production but also generates high-value byproducts. In this study, we developed a ternary photoanode, Co-LDH/Bi2O3/TiO2, by loading particulate Bi2O3 and linear Co-LDH onto TiO2 nanorod for conversion production. The characterization results confirm formation of coupled interfaces between TiO2, which improves visible light utilization promotes type II heterojunctions, resulting significant suppression electron–hole recombination an improvement PEC performance. Fourier transform infrared (FT-IR) spectroscopy revealed that Co-LDH/Bi2O3/TiO2 photoanode exhibited stronger adsorption intermediate hydroxyl group more effective desorption DHA compared to binary photoanodes (Co-LDH/TiO2 Bi2O3/TiO2), high-selectivity DHA. Mechanistic studies density function theory calculations have shown Co-LDH/TiO2 oxidizes mainly through hole oxidation, Bi2O3/TiO2 radical (•OH) oxidation. Therefore, constructed (Co-LDH/Bi2O3/TiO2) dual heterojunction converts pathways •OH This work demonstrates promising strategy developing high-performance systems production, leveraging synergistic effects multisemiconductor heterojunctions multiple pathways, offering potential practical applications.
