A novel electrochemical sensor based on ZrO 2 and ZnO hybrid nanocomposites was constructed for the speci c determination of dopamine (DA) with ultra-high sensitivity and selectivity. The structure and electrochemical properties of the composites were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), automatic gas adsorption apparatus and electrochemistry. The results show that in the ZrO 2 /ZnO nanocomposite, ZrO 2 has a large speci c surface area and abundant active site, which can accelerate the oxidation reduction reaction of DA, while ZnO nanomaterials have good conductivity, which can improve the adsorption ability of the sensor to DA. The detection limit of the electrochemical sensor is 94.1 nM in the linear range of 0.5~100 μM. Assays were performed using human serum samples at physiological pH, the recovery rate was 98.5%~101.0%, and the relevant standard deviations were less than 5%. This indicates that the electrochemical sensor is promising for bioanalysis and disease monitoring.

Photocatalysis is considered a promising and efficient oxidation technique for wastewater treatment. Developing more environmentally biocompatible, simple, effective, and inexpensive photocatalysts enables photocatalysis technology to be at the forefront of wastewater treatments. As an alternative to harmful chemicals, this work focused on the biosynthesis of a variety of ZnO and doped ZnO based on the extract of the brown alga Cystoseira crinite. X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDX), Fourier transform‐infrared (FTIR) spectroscopy, and ultraviolet–visible (UV–vis) spectroscopy were used to characterize the structure, phase, morphology, and UV–vis properties of the biosynthesized samples. XRD showed the crystalline structure of ZnO and S‐doped ZnO. SEM analysis revealed agglomerated spherical particles of the prepared samples. EDX analysis confirmed the formation of S‐doped ZnO. FTIR spectra exhibited that phenolic compounds and protein molecules are present in the Cystoseira crinite extract. The photocatalytic efficiency of biosynthesized materials was examined by monitoring the degradation of crystal violet (CV) and methyl orange (MO) dyes, which serve as cationic and anionic dye models, respectively. The various factors that influence the efficacy of the photodegradation process were investigated. In total, 5% S‐doped ZnO decomposed 97.40% and 89.18% of CV and MO dyes, respectively. The dye degradation was most efficient in samples calcined at 500 °C. The photodegradation of CV dye was enhanced at high pH, while the highest photocatalytic activity of MO dye was observed at low pH values. The kinetic study confirmed that the photodegradation follows the first‐order reaction.
