Abstract

This study reports the fabrication and characterization of activated zinc oxide (ZnO) thin films via oxygen plasma treatment for application in d-glucose oxidation. ZnO thin films were synthesized using a co-precipitation method followed by spin coating, and subsequently exposed to oxygen plasma for 6 and 9 min. Their structural and optical properties were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), atomic force microscopy (AFM), ultraviolet-visible (UV–Vis) spectroscopy, attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), and photoluminescence (PL) spectroscopy. XRD analysis revealed a reduction in the average crystallite size from 16 nm to 12 nm after plasma treatment. SEM images showed clear surface morphological modifications, while AFM indicated an increase in surface roughness from 2.85 nm to 6.03 nm due to the incorporation of oxygen-containing functional groups. UV–Vis spectroscopy showed an increase in the optical band gap from 3.26 eV to 3.32 eV. Moreover, ATR–FTIR and PL results confirmed the enhanced glucose oxidation activity of the plasma-treated ZnO thin films.

氧等离子体处理的ZnO薄膜在葡萄糖氧化中的表面研究

本研究报道了氧等离子体处理制备和表征用于d-葡萄糖氧化的活性氧化锌（ZnO）薄膜。采用共沉淀法和自旋镀膜法制备ZnO薄膜，分别在氧等离子体中暴露6和9 min。利用x射线衍射（XRD）、扫描电镜（SEM）、能量色散x射线能谱（EDX）、原子力显微镜（AFM）、紫外-可见（UV-Vis）光谱、衰减全反射傅里叶变换红外光谱（ATR-FTIR）和光致发光（PL）光谱分析了它们的结构和光学性质。XRD分析表明，等离子体处理后，晶粒的平均尺寸从16 nm减小到12 nm。SEM图像显示了明显的表面形貌改变，而AFM图像显示，由于含氧官能团的加入，表面粗糙度从2.85 nm增加到6.03 nm。紫外可见光谱显示，光学带隙从3.26 eV增加到3.32 eV。此外，ATR-FTIR和PL结果证实了等离子体处理的ZnO薄膜的葡萄糖氧化活性增强。

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
