The preparation of MgAl Layer Double Hydroxide (LDH) was performed using the coprecipitation method. Pristine LDH calcined at 500°C to produce Oxide (LDO). two materials were modified via restacking-delaminating bioactive compounds from flower extract Clitoria ternatea (CT) LDH-CT and LDO-CT. Modifications are enhance stability catalyst structure, allowing its higher photocatalytic activities regeneration use. prepared catalysts characterized XRD, FT-IR, UV-DRS, BET, SEM-EDX. XRD diffraction pattern showed that three have typical patterns commonly observed in LDH-based materials. FT-IR spectra confirmed LDO-CT combined precursor has lowest bandgap energy with highest degradation kinetics. BET SEM-EDX characterization shows uniform surface pore size on used ciprofloxacin photodegradation under UV light. optimal dose 5 mg, while pH 5. LDO-CT, LDH-CT, capacity up 73.300%, 65.739%, 71.320%, respectively, within 120 minutes. Repeated use third cycle resulted %R reaching 80.871%, 74.003%, 52.025%, by LDH. Compared pristine LDH, CT intercalated exhibited more excellent stability.

Hydrogen peroxide is widely used in medical and industrial applications, the rapid detection of low concentrations its vapor considered to be a major challenge. In this study, we have successfully implemented fabrication an MWCNTs/Fe2O3:ZnO chemoresistive sensor for hydrogen (HPV) using RF magnetron sputtering electron-beam deposition methods. The material properties structure were characterized detail scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) elementary analysis, transmission (TEM). HPV sensing performances sensors investigated temperature range 25–250 °C with without ultraviolet (UV) irradiation. Sensor response values ranged from 35 1043 7.3 198 at operating temperatures 100 (without UV irradiation) 150 (with irradiation), respectively, concentration 1.5–22 ppm. Therefore, Fe2O3:ZnO decorated MWCNTs promising candidate integration into real-life systems.

Layered Double Hydroxide (LDH)-derived materials exhibited different characteristics from LDH precursors. The conversion of ZnAl into its derivative material has been carried out to find the best catalyst for TC degradation. (LDH)-based catalysts in this study have effectively synthesized using coprecipitation, calcination, and restacking procedures. Oxide (LDO) is derived calcination at 500°C. was also modified by adding Garcinia mangostana pericarp extract (GME). XRD, FT-IR, UV-DRS, SEM-EDX were used investigate catalyst. typical FT-IR spectra, whereas LDO showed metal oxide-like ZnAl-GME composite displayed combination spectra precursor material. XRD diffraction pattern attributes a layered material, other three did not. Calcination destroyed structure LDH, addition GME generated single-layered composite. decrease both particle size bandgap energy. At an ideal pH 5, batch system photodegradation 5 mg/L Tetracycline (TC), employing solar light irradiation. holds most significant catalytic activity structural stability through fifth regeneration cycle, degraded up 100% 90 minutes.

A photocurrent-polarity-switching photoelectrochemical (PEC) biosensor was developed for the ultrasensitive detection of tobramycin (TOB) through bipedal DNA walker amplification with hemin-induced using a laser-induced zinc oxide/graphene (ZnO/LIG) photoelectrode. Specifically, ZnO/LIG photoelectrode synthesized in situ by laser direct writing (LDW) technique. In presence TOB, it reacted HP1 and HP2 response activated to form stable hemin/G-quadruplex. Furthermore, hemin induced polarity shift photocurrent signal. The analytical platform exhibited excellent photoelectron transport performance ZnO/LIG, signal effect strategy, ability hemin. Therefore, demonstrated satisfying responses target TOB within working range 20 nM-1.0 μM at low limit 5.43 nM. PEC good stability, reproducibility, sufficient sensitivity high selectivity complex experimental samples. Moreover, improved anti-interference avoided false positives or negatives.
