Bu çalışmada, çinko oksit (ZnO) nanoparçacıkları (NPs) çam kabuğu özütü kullanılarak yeşil sentez tekniği ile üretilmiştir. İndirgeyici ve dengeleyici bir madde olarak görev alan çam kabuğu özütü üç farklı oranda kullanılarak ZnO NP’leri sentezlenmiştir. Üretilen ZnO NP'leri X-ışını kırınımı (XRD), taramalı elektron mikroskobu (SEM), enerji dağılımlı X-ışını spektrum analizi (EDS) ve ultraviyole-görünür ışık spektroskopisi (UV-VIS) kullanılarak karakterize edildi. XRD kırınım piklerinin ZnO’nun karakteristik pikleriyle uyumlu olduğu ve hekzagonal wurtzit kristal fazında üretildiği belirlendi. SEM görüntülerinden numunelerin homojen bir şekilde üretildiği, parçacıkların hemen hemen küresel geometriye sahip olduğu ve ortalama parçacık boyutunun 20-30 nm aralığında olduğu belirlendi. Elementel analizde sadece Zn ve O elementleri gözlenerek, safsızlık atomlarının bulunmadığı tespit edildi. Ayrıca, ZnO NP’lerinin fotokatalitik aktivitesinin belirlenmesi için UV ışığı altında metilen mavisi (MB) boyasının bozunma performansı incelendi. Çam kabuğu özütü kullanarak sentezlenen ZnO NP’lerinin 80 dakikalık UV aydınlatması sonrasında MB’yi yaklaşık %66 oranında bozunma aktivitesine ulaştırdığı belirlendi.

Green Synthesis of ZnO Nanoparticles Using Pine Bark Extract

Öz

In this study, zinc oxide (ZnO) nanoparticles (NPs) were synthesized by green synthesis technique using pine bark extract. ZnO NPs were synthesized in three different pine bark extract ratios, which acts as a reducing and stabilizing agent. The produced ZnO NPs were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrum analysis (EDS) and ultraviolet-visible light spectroscopy (UV-VIS).It was determined that the XRD diffraction peaks were consistent with the characteristic peaks of ZnO, and ZnO NPs were produced in the hexagonal wurtzite crystal phase. It was determined from the SEM images that the samples were produced homogeneously which have almost spherical geometry and the average particles were in the range of 20-30 nm. In the elemental analysis, only Zn and O elements were observed without any impurity atoms. Also, the degradation performance of methylene blue (MB) dye under UV light was determined to determine the photocatalytic activities of ZnO NPs. It was determined that MB reached almost 66% degradation efficiency after 80 minutes of UV illumination of ZnO NPs synthesized by using pine bark extract.
