Aloe Vera Extract-Assisted Hydrothermal Synthesis of CuO Nanoparticles for Photocatalytic Degradation of Methylene Blue Dye

Abstract

Different plant extract-assisted hydrothermal synthesis offers an eco-friendly alternative to traditional approaches for sustainable technological production. Our research explores this environmentally beneficial terrain by presenting copper oxide nanoparticles (CuO NPs) created from Aloe Vera extract. This study contributes to the economical and environmentally friendly green synthesis of CuO NPs by thoroughly investigating synthesis parameters and operating parameters. Using methylene blue (MB) as a model dye, the photocatalytic characteristics of the resulting nanoparticles were examined. The synthesis factors influencing photocatalytic activity efficiency were examined, and the best circumstances were established. When the CuO photocatalyst developed under optimal conditions was used, the degradation efficiency of MB dye was 18.39%, 98.53%, and 83.46% for dark, UV, and visible light, respectively for 90 min reaction time. The influence of catalyst quantity, dye concentration, and reusability on operational parameters was then investigated. This environmentally friendly synthesis process is affordable and simple to utilize for commercial production of CuO NP on a large scale for applications connected to health.

Aloe Vera Ekstraktı Varlığında Hidrotermal Sentez Yöntemiyle Metilen Mavisi Boyasının Fotokatalitik Bozunması İçin CuO Nanoparçacıklarının Üretimi

Abstract

Farklı bitki özütleri ile desteklenen hidrotermal sentez, sürdürülebilir teknolojik üretim için geleneksel yaklaşımlara çevre dostu bir alternatif sunmaktadır. Araştırmamız, Aloe Vera özütünden üretilen bakır oksit nanopartiküllerini (CuO NP'ler) sunarak bu çevreye faydalı alanı incelemektedir. Bu çalışma, sentez parametrelerini ve işletme parametrelerini kapsamlı bir şekilde inceleyerek CuO NP'lerin ekonomik ve çevre dostu yeşil sentezine katkıda bulunmaktadır. Model boya olarak metilen mavisi (MB) kullanılarak, elde edilen nanopartiküllerin fotokatalitik özellikleri incelenmiştir. Fotokatalitik aktivite verimliliğini etkileyen sentez faktörleri incelenmiş ve en iyi koşullar belirlenmiştir. Optimal koşullar altında geliştirilen CuO fotokatalizörü kullanıldığında, 90 dakikalık reaksiyon süresi için MB boyasının bozunma verimliliği karanlıkta %18,39, UV'de %98,53 ve görünür ışıkta %83,46 olmuştur. Daha sonra katalizör miktarı, boya konsantrasyonu ve tekrar kullanılabilirliğin işletme parametreleri üzerindeki etkisi araştırılmıştır. Bu çevre dostu sentez süreci, sağlıkla ilgili uygulamalar için CuO nanopartiküllerinin büyük ölçekli ticari üretimi için uygun fiyatlı ve kullanımı kolaydır.
