Special Issue "Nanocatalysts for Environmental Remediation"
Deadline for manuscript submissions: 25 February 2024 | Viewed by 4397
The global population is booming and production activities are ever-growing, leading to the discharging of various pollutants into the environmental media (e.g., soil, water, and air). When the concentration of the pollutants exceeds certain limits and poses great risks to the environment and human health, remediation actions are necessary. Techniques such as adsorption, biological treatment, physicochemical reactions, and membrane filtration are usually studied for environmental remediation. In the last decade, nanomaterials, owing to their large surface area, high surface reactivity, and multifunctional properties, have been studied extensively for environmental applications. Among various nanotechniques, nanocatalyst-based physicochemical methods with high reactivity for oxidation or reduction reactions are one of the most promising techniques for pollutants’ transformation and removal. Though significant progress has been made in recent years, the poor stability, costliness of preparation and applications, and potential toxicity to the environment are the main obstacles that limit nanocatalysts’ use for practical applications. Thus, green, sustainable, and cost-effective nanocatalysts are in demand for the development of state-of-the-art nanotechnologies for environmental remediation.
This Special Issue aims to present state-of-the-art nanocatalysts and related nanotechnologies for water, soil, or air remediation. We invite authors to contribute original research articles and review articles covering the current progress on nanocatalysts for environmental remediation. Potential topics include, but are not limited to:
- Nanocatalysts for soil/water remediation.
- Nanocatalysts mediated AOPs for wastewater treatment.
- Nanocatalysts for volatile organic compounds’ removal.
- Nanocatalysts for sterilization and disinfection.
- Nanocatalysts for CO2
- Coupled techniques for environmental remediation mediated by nanocatalysts.

Abstract: Halloysite nanotubes (HNTs) are nature-generated clay materials with nanotube structures. They have a large outer diameter of the Si-O group on the outside and the Ai-O group on the inside. HNTs is used in various applications with 10 Å interlayer spaces and high absorption. Graphene oxide (GO) is a sp2 bond and a light conductive material. As a result, it has a good adsorption component. In this study, we used the synergistic adsorption of HNTs and GO as the motivation. Photocatalytic experiments were conducted based on the use of the two as catalysts. ZnO is a semiconductor material with a band gap of 3.17 eV, which has been often used as a photocatalysis for degradation of organic dye. However, raw ZnO nanoparticles are poorly active in large amounts and for long time photocatalysis due to its strong aggregation. To overcome this issue, we combined adsorptive HNTs and GO with ZnO to create new nanocomposite consisting of GO/HNTs/ZnO. The nanocomposites were characterized using scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), ultraviolet–visible spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, x-ray Diffraction (XRD). It was found that GO/HNTs/ZnO nanocomposites showed higher photocatalytic effect for degradation of organic dyes by ~5 times compared with ZnO or HNTs/ZnO materials.
