“…In particular, VOCs such as benzene, toluene, and xylene have been regulated due to them causing cancer or odor [ 4 , 5 , 6 ]. In the Republic of Korea, VOCs are among the main air pollutants, and around 55% of secondary atmospheric particulate matter is derived from organic compounds, such as toluene [ 7 , 8 , 9 ]. The VOCs are transformed in the air into secondary atmospheric particulate matter via photochemical reaction, leading to environment pollution.…”

A volatile organic compound adsorbent based on a porous clay heterostructure (PCH) with alginate biopolymer was successfully prepared. From N2 adsorption–desorption analysis, the specific surface area, pore volume, and pore size of bentonite were dramatically increased after introducing the porous structure. Following complexation with alginate (Alg-PCH), the pore volume and pore size were not significantly affected by pore structure. The thermal stability of Alg-PCH shows enhanced thermal stability compared to alginate and alginate beads. The morphology layered structure of Alg-PCH was carried out by transmission electron microscopy (TEM), suggesting the disorder and re-order of the c-axis layer stacking by porous structure and complexation with alginate, respectively, which was well-matched with X-ray diffraction results. To optimize the preparation of Alg-PCH, various reaction conditions (alginate, CaCl2 concentration, bead size, and weight ratio between alginate and PCH) were utilized. According to the toluene adsorption–desorption experiments, the preparation conditions for Alg-PCH were selected as a 2 mm extrusion tip, 0.5% of alginate, and 2% of CaCl2 solution with a 1:50 alginate:PCH weight ratio. Additionally, it shows 61.63 mg/g adsorption capacity with around 49% desorption efficacy under atmospheric temperature and pressure.

“…Despite the associated improvement in safety rules and economic benefits, the risks of hazardous chemical accidents are serious, such as hydrogen fluoride leakage 9 . According to the statistical report of the National Institute of Chemical Safety in Republic of Korea, hazardous chemicals including hydrogen fluoride, hydrogen chloride (HCl), nitric acid, ammonia, H 2 O 2 , chlorine gas, formaldehyde, aromatic compounds such as benzene‐toluene‐xylene (BTX), and heavy metal are major contaminants in chemical accidents 10 . Considering reports that toxic heavy metal elements may threaten safety, mercury, cadmium, lead, and others should also be checked after chemical accidents 11 .…”

Chemical accidents, such as fire, explosion, and leakages, not only cause damage to humans but also have a harmful impact on the environment. In modern industrialization period, researchers have been attracted by the elaboration of novel detection platforms that have been widely adopted for monitoring and the early warning of the risk of hazardous chemicals including hydrogen fluoride, hydrogen chloride, nitric acid, ammonia, hydrogen peroxide, chlorine gas, formaldehyde, aromatic compounds such as benzene‐toluene‐xylene, and heavy metals. This review explores novel sensor platforms based on novel materials including plasmonic metals, transition metal oxides, and composites. Due to the unique optical, spectroscopic, electrical, and physicochemical properties of materials, the development of functional materials‐based sensors significantly augments the current outlook on reducing the risk of hazardous chemical accidents to ensure security for humans and the environment.
