SÜRDÜRÜLEBİLİR CuO NANOKATALİZÖR: METİLEN MAVİSİ VE KRİSTAL VİYOLENİN FOTOKATALİTİK BOZUNUMU

Abstract

Bu çalışmada nane (Mentha spicata) bitki özütü kullanılarak çevre dostu bir yeşil sentez yöntemiyle CuO nanoparçacıklar (NP’ler) sentezlenmiştir. Elde edilen CuO nanoparçacıklarının yapısal, optik ve fotokatalitik özellikleri sistematik olarak incelenmiştir. Sentezlenen CuO nanoparçacıkları XRD, FE-SEM, FT-IR ve UV-Vis analizleri kullanılarak karakterize edilmiştir. Elde edilen sonuçlar, monoklinik kristal yapıya sahip nano boyutlu CuO parçacıklarının oluştuğunu ve bitki özütündeki fitokimyasal bileşenlerin nanoparçacık yüzeyinde stabilizasyon sağladığını göstermiştir. Sentezlenen CuO nanoparçacıklarının fotokatalitik aktivitesi, 300 W’lık ksenon lamba altında görünür ışık koşullarında metilen mavisi (MB) ve kristal viyole (CV) boyalarının bozunması ile değerlendirilmiştir. Artan ışınlama süresiyle boya konsantrasyonunda kademeli bir azalma meydana gelmiş ve 105 dakika sonunda MB için %92,4 CV için ise %83,2 bozunma verimine ulaşılmıştır. Kinetik analiz sonuçları, her iki boyanın bozunma sürecinin sözde birinci dereceden reaksiyon modeline uyduğunu ve sürecin yüzey kontrollü fotokatalitik mekanizma ile gerçekleştiğini göstermiştir. Elde edilen bulgular, yeşil sentez yöntemi ile üretilen CuO nanoparçacıklarının görünür ışık altında etkin fotokatalitik performans sergilediğini ve atık su arıtımı ile çevresel iyileştirme uygulamaları için önemli bir potansiyele sahip olduğunu ortaya koymuştur.

SUSTAINABLE CuO NANOCATALYST: PHOTOCATALYTIC DEGRADATION OF METHYLENE BLUE AND CRYSTAL VIOLET

Abstract

This study reports the green synthesis of CuO nanoparticles (NPs) using mint (Mentha spicata) leaf extract as an environmentally friendly reducing and stabilizing agent. The structural, optical, and photocatalytic properties of the synthesized CuO nanoparticles were systematically investigated. The nanoparticles were characterized by XRD, FE-SEM, FT-IR, and UV-Vis analyses. The results confirmed the formation of nanosized CuO particles with a monoclinic crystal structure and indicated that phytochemical compounds present in the plant extract contributed to the surface stabilization of the nanoparticles. The photocatalytic activity of the synthesized CuO nanoparticles was evaluated through the degradation of methylene blue (MB) and crystal violet (CV) dyes under visible light irradiation using a 300 W xenon lamp. A gradual decrease in dye concentration was observed with increasing irradiation time, and maximum degradation efficiencies of 92.4% for MB and 83.2% for CV were achieved after 105 minutes. Kinetic analysis revealed that the degradation of both dyes followed a pseudo first order reaction model, indicating a surface controlled photocatalytic process. Overall, the findings demonstrate that green synthesized CuO nanoparticles exhibit efficient visible light driven photocatalytic performance and hold significant potential for wastewater treatment and environmental remediation applications.
