Industrial effluents containing dyes are the dominant pollutants, making drinking water unfit. Among dyes, methylene orange (MO) dye is mutagenic, carcinogenic and toxic to aquatic organisms. Therefore, its removal from bodies through effective economical approach gaining increased attention in last decades. Photocatalytic degradation has ability convert economically complex molecules into non-toxic smaller species via redox reactions, by using photocatalysts. g-C3N4 a metal-free n-type semiconductor, typical nonmetallic non-toxici polymeric photocatalyst. It widely used photocatalytic materials, due easy simple synthesis, fascinating electronic band structure, high stability abundant availability. As photocatalyst, major drawbacks limited efficiency separating photo-excited electron–hole pairs, separated charge recombination, low specific surface area, absorption coefficient. In this review, we report recent modification strategies adopted for efficient photodegradation of MO dye. The different approaches, such as nanocomposites heterojunctions, well doping defect introductions, briefly discussed. mechanism future perspectives This review paper will predict fabrication an g-C3N4-based photocatalyst

As emerging contaminants in the environment, antibiotic resistance genes (ARGs) have aroused a global health crisis and posed serious threat to ecological safety human health. Thus, efficient accurate onsite detection of ARGs is crucial for environmental surveillance. Here, we presented colorimetric-photoelectrochemical (PEC) dual-mode bioassay simultaneous multiple by smartly incorporating rolling circle amplification (RCA) into stimuli-responsive DNA nanoassembly, using tetracycline tetA tetC as models. The tailored nanoassembly containing RCA amplicons hybridized with specific signal probes: CuO nanoflowers-anchored DNA1 HgO nanoparticles-anchored DNA2, respectively. Upon exposure an acidic stimulus, numerous Cu2+ Hg2+ were released, serving reporting agent colorimetric/PEC assay. released induced localized surface plasmon resonance shifts Au nanorods triangular Ag nanoplates through etching process, respectively, enabling visual analysis distinguishing color changes. Meanwhile, triggered amplified PEC variations via reacting photoactive layers CuS/CdS ZnS, rapid ultrasensitive was achieved limit down 17.2 aM. Furthermore, such could discriminate single-base mismatch successfully determine E. coli plasmids sludge samples, holding great promise point-of-care genetic diagnostics.

Water contamination by nitro compounds from various industrial processes has significantly contributed to environmental pollution and severely threatened aquatic ecosystems. Inexpensive, efficient, environmentally benign catalysts are required for the catalytic reduction of such compounds. This study reports fabrication nanocomposites (NCs) copper oxide nanoparticles (CuO NPs) supported on a kaolin sheet using straightforward simple one-pot synthesis procedures that control metal precursor ratios. The selected as-synthesized CuO/kaolin NC was characterized range advanced spectroscopic microscopic methods, as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), ultraviolet–visible (UV–vis) spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission (TEM), energy dispersive (EDX), high-angle annular dark-field TEM (HAADF-STEM), N2 adsorption/desorption analysis. characterization results confirmed successful incorporation CuO NPs into sheets, which had an average size about 18.7 nm. fabricated used heterogeneous catalyst efficient 4-nitrophenol (4-NP) 4-aminophenol (4-AP) in presence sodium borohydride (NaBH4) aqueous system at room temperature. demonstrated superior performance with high 4-NP conversion 4-AP (>99%) phase (50 mL, 20 mg L–1) within 6 min. In addition, reaction kinetics also investigated, followed pseudo-first-order equation apparent rate constant 1.76 min–1. Furthermore, Arrhenius Eyring parameters hydrogenation were calculated order investigate process more detail. Moreover, exhibited excellent reusability stability over seven repeated test cycles without any noticeable decline activity. Therefore, this paper could provide novel, promising clay-based non-noble nanocatalyst reduce system.
