Green synthesis of gold nanoparticles (AuNPs) is gaining attention of researchers because of their varieties of biomedical and environmental applications. This study reported the novel eco‐friendly synthesis of AuNPs using green macroalgae Halimeda macroloba (HM) extract and evaluate their photocatalytic potential. The green synthesized H. macroloba mediated gold nanoparticles (HM‐AuNPs) was characterized using UV–visible spectrophotometry, Fourier‐transform infrared (FT‐IR) spectroscopy, transmission electron microscope (TEM), scanning electron microscope‐energy dispersive spectroscopy, x‐ray photoelectron spectroscopy (XPS), and particle size distribution (PSD) anlaysis. The UV–visible spectrum shows a sharp intense plasmonic resonance peak at 543 nm. The bioactive compounds present in HM were primarily responsible for the biological reduction of gold ions validated by FT‐IR analysis. XRD analysis proved the crystalline face centered cubic structure of the HM‐AuNPs. The average particle size of 18.72 nm and morphological evidences were obtained from the images from TEM. The metallic form of biosynthesised HM‐AuNPs was confirmed by XPS results with a distinctive binding energy. The photocatalytic degradation ability of the green synthesized HM‐AuNPs was investigated against the methylene blue (MB) and methylene orange (MO) dyes under sunlight irradiation. The HM‐AuNPs exhibited 97.23% and 89.91% photocatalytic activity against MB and MO after 90 min of exposure to sunlight, respectively. The overall results of this research indicate that H. macroloba mediated HM‐AuNPs can be used as an effective option for the degradation of industrial dyes.

With the development of society, antibiotics have been widely used in human and animal bacterial infections [1]. Due to their limited biodegradability, they can be detected in soil, surface water, and surface sediments [2]. Oxytetracycline (OTC) is a tetracycline antibiotic with a broad range of action. Because of its inexpensive cost and therapeutic impact, OTC is commonly utilized in aquaculture and animal husbandry. Once OTC is extensively used and not properly treated, the residual OTC will harm the ecological environment [3]. The issues contain bacterial resistance and resistance genes. Therefore, the impact of antibiotic resistance on human health needs to be

Pharmaceutical substances, a pill for every ill, have become a sweet poison by remarkably boosting the global economy as well as human and animal wellness and at the same time causing environmental pollution, especially in the aquatic ecosystem, and this has led to a fatal diminution in the availability of clean water and upsurge in water insecurity. Notably, traditional techniques and materials have been employed to clean up pharmaceutical pollutants (PP) from aquatic bodies; however, they have come under controversy because they require hazardous chemicals and cannot fully mineralize stubborn PPs. Interestingly, the photocatalytic degradation approach employing eco‐benign biosynthesized nanoparticles (BNP) is an avant‐garde practice and has shown to be an eco‐sustainable method that can fully mineralize PPs into harmless molecules. Thus, this study critically explores the application of BNPs for the photocatalytic degradation of PPs. The review revealed that the greatest degradation efficacy of BNPs was greater than 80% in most cases, and that the least amount of time required was around 10 min. In addition, the oxygen‐containing functional groups found in the biological sources used for the fabrication of BNPs contributed to the supremacy of •OH and O2• radicals in the degradation operation. Also, the photocatalytic degradation kinetic data was well modeled by pseudo‐first order, and this indicates that •OH was more involved in the PPs degradation operation than O2•. Moreso, BNPs have excellent reusability potential (>5 rounds) while maintaining inherent structural integrity. Techno‐economic analysis revealed that BNPs are cost‐effective, costing about $1.5/1,000,000 mL of pharmaceutical wastewater on average.
