Special Issue Information

Dear Colleagues,

Today, environmental pollution is a major problem facing the world. The main sources of land, water and air pollution are extensive industrialization and intensive agricultural activities. Nanomaterials have attracted a lot of interest in environmental remediation. Due to their large surface area and associated high reactivity, nanomaterials perform better than other conventional methods for environmental cleanup. They act on environmental contaminants as small structures or small-sized particles that can be modified for specific applications to provide new functions. Nanoscale materials can be extremely reactive due to the large surface-area-to-volume ratio and the presence of more reactive sites. These characteristics allow for higher interaction with pollutants, leading to a rapid reduction in pollutant concentrations.

The present Special Issue of Nanomaterials is aimed at presenting the current state-of-the-art in the use of nanomaterials and nanotechnology in pollutant detection and removal. We invite authors to contribute original research articles and review articles.

Volatile organic compounds (VOCs), particularly monoaromatic hydrocarbon compounds (MACHs), pose a potential risk to the atmospheric environment and human health. Therefore, the progressive development of efficient detection methodologies is a pertinent need, which is still a challenge at present. In this study, we present a rapid and sensitive method to detect trace amounts of MACHs using a bifunctional SERS composite substrate. We prepared an Au/SiO2 enhanced layer and a porous Cu(OH)2 adsorption layer via microfluidic-assisted gas-liquid interface self-assembly. The composite substrate effectively monitored changes in benzaldehyde using time-varying SERS spectra, and track-specifically identified various VOCs such as benzene, xylene, styrene, and nitrobenzene. In general, the substrate exhibited a rapid response time of 20 s to gaseous benzaldehyde, with a minimum detection concentration of less than 500 ppt. Further experimental assessments revealed an optimum Cu(OH)2 thickness of the surrounding adsorption layer of 150 nm, which can achieve an efficient SERS response to MACHs. Furthermore, the recoverable and reusable property of the composite substrate highlights its practicality. This study presents a straightforward and efficient approach for detecting trace gaseous VOCs using SERS, with significant implications in the designing of SERS substrates for detecting other VOCs.
