Advancement in nanomaterials for environmental pollutants remediation: a systematic review on bibliometrics analysis, material types, synthesis pathways, and related mechanisms

Nosheen Asghar,
Alamdar Hussain,
Duc Anh Nguyen
et al.

Abstract: Environmental pollution is a major issue that requires effective solutions. Nanomaterials (NMs) have emerged as promising candidates for pollution remediation due to their unique properties. This review paper provides a systematic analysis of the potential of NMs for environmental pollution remediation compared to conventional techniques. It elaborates on several aspects, including conventional and advanced techniques for removing pollutants, classification of NMs (organic, inorganic, and composite base). The … Show more

“…The use of nanomaterials enhances the processes of adsorption and oxidation, enabling the degradation and removal of micropollutants that persist in the soil environment . Widely used nanotechnological applications in soil remediation for contaminant removal include carbon nanomaterials, iron­(III) oxide (Fe 3 O 4 ), titanium oxide (TiO 2 ), zinc oxide (ZnO), nZVI, and nanocomposites . Notably, nZVI is the most commonly used nanoparticle for eliminating heavy metal pollutants owing to its high efficiency in transforming contaminants such as toxic metals, chlorinated organic compounds, and inorganic compounds into less harmful forms …”

“…These sensors are categorized based on their performance, cost effectiveness as well as working conditions. A smart IAQ monitoring network works with on-the-go data transfer from sensors to server on cloud for subsequent IAQ processing and evaluation ( Husain et al, 2007 ; Arar and Jung, 2022 ; Asghar et al, 2024 ). IoT based network also comprises of end equipment and communication exchange facilities.…”

“…IoT-based systems have brought significant advancements to air quality monitoring in the Middle East, leading to a deeper understanding of pollution trends, notable improvements, and positive changes in public awareness and policies. IoT-based systems provide real-time and precise data on air quality, allowing for the identification of pollution hotspots and the sources of contaminants ( Him et al, 2019 ; Sai et al, 2019 ; Bousiotis et al, 2021 ; Saini et al, 2021 ; Buelvas et al, 2023 ; Asghar et al, 2024 ). Continuous monitoring has revealed seasonal and diurnal pollution patterns, aiding in the development of targeted mitigation strategies ( Chen et al, 2015 ; Ammar et al, 2018 ; Din et al, 2019 ; Hassan et al, 2020 ; Saini et al, 2021 ; Saini et al, 2021 ; Buelvas et al, 2023 ).…”
