Abstract

Background

The widespread use of methylene blue (MB) dye in industrial applications has resulted in severe water pollution, posing environmental and public health challenges. Conventional wastewater treatment methods often fall short in effectively removing organic dyes, necessitating the development of advanced photocatalytic solutions.

Methods

Vanadium pentoxide (V₂O₅) nanosheets were synthesized via a hydrothermal method using the surfactant Pluronic P123 to minimize agglomeration. The nanosheets demonstrated enhanced photocatalytic properties due to their increased surface area and reduced electron-hole recombination. Under compact fluorescent lamp illumination, their ability to degrade MB dye was systematically evaluated, achieving a degradation efficiency of 97.96 % within 150 min.

Significant findings

The superior catalytic activity of V₂O₅ nanosheets was attributed to their porous structure and oxalic acid-induced thinner morphology, which facilitated enhanced H⁺ ion interaction. These nanosheets offer a promising approach for visible-light-driven dye degradation, providing a sustainable and efficient solution for wastewater treatment and environmental remediation.

水热合成V2O5纳米片高效降解亚甲基蓝：一种可持续废水处理的创新方法

亚甲基蓝染料在工业应用中的广泛使用造成了严重的水污染，对环境和公共卫生构成了挑战。传统的废水处理方法往往不能有效地去除有机染料，因此需要开发先进的光催化溶液。方法采用水热法制备五氧化二钒（V2O5）纳米片，以Pluronic P123为表面活性剂，减少团聚现象。纳米片由于其增加的表面积和减少的电子-空穴复合而表现出增强的光催化性能。在紧凑型荧光灯照射下，系统评价了它们对MB染料的降解能力，在150 min内降解效率达到97.96%。V2O5纳米片优异的催化活性归因于其多孔结构和草酸诱导的更薄的形貌，这有助于增强H +离子的相互作用。这些纳米片为可见光驱动染料降解提供了一种很有前途的方法，为废水处理和环境修复提供了可持续和高效的解决方案。
