Article Abstract

To improve the indoor air quality of apartments in Korea, a toluene adsorptive paint was manufactured and tested for its efficiency to remove the indoor toluene released from wallpaper adhesives. The toluene adsorptive paint was prepared by blending activated carbon and inorganic binder, and the pore characteristics and chemical functional groups of the activated carbon were analyzed to determine whether the micropores and surface functionalities of activated carbon affected toluene adsorption. Toluene adsorption performance of the toluene adsorptive paint was confirmed through static and verification experiments. The average adsorption efficiency of toluene adsorptive paint in the static experiment was 98.3% and the verification experiment confirmed that about 96.3% of toluene was adsorbed from the indoor air of the apartment. As a result, the use of toluene adsorptive paint effectively removes toluene, which may occur in the adhesive, and thus can be considered to have a good effect on the improvement of indoor air quality. Furthermore, toluene adsorptive paint has been found to be an effective way to achieve consumer wall finishing preferences and maintenance convenience.

Efficiently activating inert C-H bonds while maintaining control over the selective pathways of complex chemical reactions involving high-energy species remains a highly challenging and as-yet unattained objective. Herein, we propose a novel concept called 'dynamic local free radical confinement-mediated mechanism' to efficiently achieve synergetic selective oxidation of toluene and hydrogen generation for the first time a CdS-CdInS semi-coherent heterojunction (CCS) under two-phase conditions. Surprisingly, the optimized CCS-2 exhibited amazing catalytic efficiency and long-term stability in gram-scale experiments and automatically separated the catalyst from the product.

Selective removal of aromatic contaminants from water matrices poses substantial difficulties in environmental remediation processes, necessitating sophisticated materials with discriminatory molecular recognition properties. Herein, we report a framework-elastomer hybrid membrane containing [Co(4-pmntd)(NO)] (4-pmntd represents ,'-bis(4-pyridylmethyl)naphthalene diimide) designed for effective toluene recovery from trace aqueous environments. Systematic structural analysis employing crystallographic diffraction, gas adsorption measurements, surface electron spectroscopy, and proton nuclear magnetic resonance elucidates the material's architectural characteristics and surface phenomena.

Achieving both high activity and good stability remains a challenge for the design of MoS-based catalysts in the hydrodeoxygenation (HDO) reaction. Herein, a robust catalyst with single-layer CoMoS anchored on hydrophobic reduced graphene oxide (SL-CoMoS/rGO) was fabricated, which exhibited high activity, selectivity and excellent stability in the HDO of lignin-derived phenolics to arenes. Utilizing the HDO of 4-methylphenol as a probe reaction, the catalyst afforded a conversion of 98.

Most studies have shown that oxygen vacancies on CeZrO solid solution are important for enhancing the catalytic oxidation performance. However, a handful of studies investigated the different roles of surface and subsurface oxygen vacancies on the performance and mechanisms of catalysts. Herein, a series of zirconium doping on CeO samples (CeO, CeZrO, and CeZrO) with various surface-to-subsurface oxygen vacancies ratios have been synthesized and applied in toluene catalytic oxidation.
