Abstract

When it comes to fabricating metal oxide nanoparticles (NPs), green synthesis stands out as a dependable, sustainable, eco-friendly, and remarkable substitute for the more effective and classical chemical processes. This study prepared and investigated green synthesis on fabrication of titanium dioxide nanoparticles (TiO₂ NPs) utilizing peel extract of Baccaurea racemosa and evaluated its photocatalytic activity. The XRD patterns demonstrated the highly crystalline structure of anatase TiO₂ with nanocrystallite size obtained about 8 nm. FESEM image confirmed spherical-shaped of TiO₂ with nanosized about 32 nm and showed that prepared TiO₂ was a stable particle from zeta potential data. The phytochemical components in the peel extract were in responsibility of the capping and reducing agents in the production of TiO₂, as indicated by the FTIR spectra. This study showed that Baccaurea racemosa waste may be a viable reducing and capping agent in synthesis of TiO₂-NPs. Furthermore, the prepared TiO₂ exhibited high photocatalytic activity and 99 % degraded the Acid Red-185 dye which fitted pseudo first order kinetics.

用总状巴氏菌皮提取物制备光催化降解酸性红-185的TiO2纳米颗粒的绿色合成方法

当涉及到制造金属氧化物纳米颗粒（NPs）时，绿色合成作为一种可靠、可持续、环保和显着的替代更有效和经典的化学过程而脱颖而出。本研究利用总形假葡萄皮提取物制备并研究了绿色合成制备二氧化钛纳米粒子（TiO2 NPs），并对其光催化活性进行了评价。XRD谱图显示了锐钛矿型TiO2的高结晶结构，纳米晶尺寸约为8 nm。FESEM图像证实TiO2为球形，纳米尺寸约为32 nm， zeta电位数据表明制备的TiO2是稳定的颗粒。FTIR光谱显示，果皮提取物中的植物化学成分在TiO2的生成过程中起封顶作用和还原剂作用。本研究表明，总状芽孢杆菌废物可能是合成TiO2-NPs的一种可行的还原和封盖剂。制备的TiO2具有较高的光催化活性，对酸性红-185染料的降解率达到99%，符合准一级动力学。

期刊介绍： Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
