Functional materials that can quickly absorb and degrade mustard gas are essential for chemical warfare emergency response kits. In this study, a fiber membrane with excellent adsorption and catalytic degradation activity was developed by solution blow spinning polystyrene (PS)/polyurethane (PU) and hydrothermal in situ growth of a zirconium-based MOF (MOF-808). The mechanical properties of the PS/PU fibers were improved by adding a trimethylolpropane tris (2-methyl-1-aziridine propionate) (TTMA) cross-linking agent. Moreover, the C═O bonds in TTMA provided abundant growth sites for MOF-808 in the hydrothermal process, thereby greatly increasing the loading capacity. The fiber surface was completely covered with the MOF-808 particles within 24 h. The PS/PU/TTMA/MOF-808 fiber membrane was used for the catalytic degradation of 2-chloroethyl ethyl sulfide (CEES). The degradation efficiency reached 97.7% after 72 h, indicating its great application potential in emergency wiping cloths for mustard gas adsorption and degradation.

Currently extensive effort is compulsively expended to decontaminate efficiently banned chemical war agents. In this work, H5PV2Mo10O40 molecules have been encapsulated in mesoporous MIL-101(Cr), which features two types of mesoporous cages (internal diameters of 29 Å and 34 Å) and microporous windows (diameters of 12 Å and 16 Å), leading to the formation of a new composite H5PV2Mo10O40@MIL-101(Cr) through a simple impregnation method. The composite was characterized thoroughly by elemental analysis, FT-IR spectroscopy, powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, TG/DTA, and textural analysis thereby confirming the encapsulation of the H5PV2Mo10O40 into MIL-101(Cr). The decontamination efficiency of sulfur mustard (4 μL HD in 40 μL of petroleum ether) by 20 mg of the composite is found to be 97.39% in 120 min under ambient conditions. GC-MS analysis on the decontaminated products using 2-chloroethyl ethyl sulfide (CEES), which has been widely used as a simulant of sulfur mustard, showed that MIL-101(Cr) just decontaminates CEES by adsorption, while CEES can be decontaminated under ambient conditions by a synergetic combination of adsorption of MIL-101(Cr) and subsequent chemical oxidation degradation to nontoxic 2-chloroethyl ethyl sulfoxide (CEESO) due to the presence of highly dispersed H5PV2Mo10O40 within the composites.

ε-[Al13O4(OH)24(H2O)12]7+, which shares similarity with the phosphotriesterase active site ZnII–OH–ZnII, was specially chosen to interact with the cluster α-PMo10V2O405− to form a new three-dimensional intercluster, which crystallized in the monoclinic space group P21/m with Z = 2, for the decontamination of chemical warfare agents. The experimental results showed that 50 mg of the compound decontaminated 96.4% (within 120 min) and 99.5% (within 40 min) of sulfur mustard (HD) (4 μL) and soman (GD) (4 μL), respectively, in ambient conditions. The decontamination processes followed first-order reaction kinetics with a rate constant and half-life of 0.01234 min−1 and 56.15 min for HD and 0.1198 min−1 and 5.78 min for GD, respectively. It was concluded that the α-PMo10V2O405− moiety was responsible for the catalytic oxidation of HD into non-toxic sulfoxide, while the ε-[Al13O4(OH)24(H2O)12]7+ moiety was responsible for the catalytic hydrolysis of HD and GD into nontoxic hydrolysates. Besides, the compound showed notable efficacy for the decontamination of HD on guinea pig skin and of GD on Kunming mouse skin, indicating high potential for use in human skin protection and treatment.

The development of very efficient bifunctional catalysts for the simultaneous detoxification of two kinds of the deadliest chemical warfare agents (CWAs), nerve agent and blister agent, is highly desirable. In this study, two porphyrin-based ligands [tetrakis(4-carboxyphenyl) porphyrin (TCPP) and protoporphyrin IX (PPIX)] are introduced into 2D Zr-1,3,5-tris(4-carboxyphenyl)benzene (BTB) metal–organic layers (MOLs), composed of six-connected Zr6 nodes and the tritopic carboxylate ligand BTB, by a solvent-assisted ligand incorporation method. The loads of TCPP and PPIX are 6.4 and 10.9 wt %, respectively. The detoxification of simulants of the nerve agent and the blister agent was conducted to investigate the catalytic activity of porphyrin-moiety-functionalized MOLs. The reaction half-life of optimal TCPP-functionalized MOL catalyzing the hydrolysis of a nerve agent simulant is only 2.8 min, meanwhile, the half-life of the selective catalytic oxidation of a blister agent simulant is only 1.2 min under LED illumination. More importantly, such a degradation half-life is only about 4 min under natural sunlight (∼60 mW/cm2). To our knowledge, TCPP-functionalized MOL is by far the most efficient catalyst for blister agent simulant degradation under solar light. Therefore, 2D ultrathin MOLs on demand appear to be a promising and efficient material platform for the development of bifunctional catalysts for CWA protection.

Developing reliable and portable sensors for detection of highly toxic mustard gas is extremely important for public security. However, gas sensors based on pristine metal oxide semiconductors often suffer from high working temperature, inferior response, and inadequate detection limit owing to their poor intrinsic conductivity and weak adsorption toward target gases, thereby hindering their wide application. Herein, hierarchical WO 3 -Bi 2 WO 6 heterostructures were fabricated as sensing materials to comprehensively improve their sensing properties to 2-chloroethyl ethyl sulfide (2-CEES, a mustard gas simulant). The optimized sensor based on WO 3 -Bi 2 WO 6 -2 displayed short response time of 1.4 s and high sensing response (R a /R g = 63) to 50 ppm 2-CEES at 133 °C, together with an ultra-low detection limit of 10 ppb. The improvement of WO 3 -Bi 2 WO 6 -2 in sensing properties are synergistically attributed to the amount of heterojunction and surface adsorption sites, which were proved by DFT calculations and a series of characterizations. This work might pave the way for further developing heterostructure-based sensors for 2-CEES detection with superior sensing properties.

Atmospheric pressure plasma jet (APPJ), as an emerging clean and efficient technology, has been found a great potential for chemical warfare agents (CWAs) decontamination. In this study, we first proposed APPJ for the degradation of sulfur mustard (HD) and its surrogate 2-chloroethyl ethyl sulfide (2-CEES) in water. Under optimal conditions, the degradation efficiency of 2-CEES and HD reached 100 % after 5 min or 6 min plasma treatment. The degradation products of 2-CEES and HD were mainly non-toxic alcohols or low toxic sulfones, which can be degraded and converted into some small molecules (HCl, SO 2 , or CO 2 ) under further plasma treatment. We then identified two dominant short-lived reactive species (·OH and 1 O 2 ) and long-lived reactive molecule (H 2 O 2 ) and distinguished the effect of these three active particles during the degradation process of 2-CEES in water. This work provides detailed evidence of a novel decontamination strategy for HD and 2-CEES.

By combining the anionic salt meso-tetra(4-carboxyphenyl)porphyrin (TCPP4−) and the Keggin polyoxometalate cation cluster [Al13O4(OH)24(H2O)12]7+ via a simple ion-exchange method, a hybrid (C48H26N4O8)[Al13O4(OH)24(H2O)12]2(OH)10·18H2O (Al13–TCPP) was prepared and thoroughly characterized as a prototype of polyoxometalate–porphyrin hybrids for the photocatalytic degradation of the mustard gas simulant 2-chloroethyl ethyl sulfide (CEES). The experimental results showed that the catalytic degradation rate of CEES in the presence of Al13–TCPP reached 96.16 and 99.01% in 180 and 90 min in methanol and methanol–water solvent mixture (v/v = 1 : 1), respectively. The reaction followed first-order reaction kinetics, and the half-life and kinetic constant in methanol and solvent mixture were 39.8 min, −0.017 min−1 and 14.7 min, −0.047 min−1. Mechanism analysis indicated that under visible light irradiation in air, CEES was degraded through a combination of oxidation and alcoholysis/hydrolysis in methanol and the methanol–water solvent mixture. The superoxide radical (O2˙−) and singlet molecular oxygen (1O2) generated by Al13–TCPP selectively oxidized CEES into a non-toxic sulfoxide. The singlet oxygen capture experiments showed that Al13–TCPP (Φ = 0.236) had a higher quantum yield of singlet oxygen generation than H4TCPP (Φ = 0.135) under visible light irradiation in air. The material Al13–TCPP has good reusability, and the degradation rate of CEES can still reach 98.37% after being recycled five times.

The poor selectivity of metal oxide semiconductor sensors is a major constraint to their application in the detection of chemical warfare agents. We prepared a (Pt+Pd+Rh)@Al2O3/(Pt+Rh)-WO3sensor by using (Pt+Pd+Rh)@Al2O3as a catalytic film material and (Pt+Rh)-WO3as a gas-sensitive film material. Using temperature dynamic modulation, the (Pt+Pd+Rh)@Al2O3/(Pt+Rh)-WO3sensor was realised to improve the selectivity for mustard. Due to the catalytic effect of the (Pt+Pd+Rh)@Al2O3catalytic film on mustard, mustard was able to be catalytically generated into mustard sulphoxide after passing through the (Pt+Pd+Rh)@Al2O3catalytic film. Under a certain temperature dynamic modulation, the mustard concentration on the surface of the (Pt+Rh)-WO3gas-sensitive film showed an increase and then a decrease. Since the resistance response of the (Pt+Rh)-WO3gas-sensitive film to mustard was much higher than that of mustard sulphoxide, the change in the resistance of the (Pt+Rh)-WO3gas-sensitive film was mainly determined by the change in the concentration of mustard, which led to the peak signal in the curve of its resistance response to mustard. The experimental results showed that the (Pt+Pd+Rh)@Al2O3/(Pt+Rh)-WO3sensor had peak signals in the resistance response to mustard only, and not in the resistance response to 12 interfering gases, such as carbon monoxide.

Sulfur mustard (2,2′-dichloroethylsulfide; SM) is a bifunctional alkylating agent that can easily penetrate skin and cause persistent pain and damage. Effective biological dressings are required to treat wounds caused or poisoned by SM. Though the use of SM is regulated under the Chemical Weapons Convention, it is still a threat during wars and terrorist attacks. Herein, we present a photothermal-enhanced detoxification microneedles array (MNA) encapsulated with ZnIn 2 S 4 @UiO-66-NH 2 (ZnInS/UIO) catalysts for the treatment of 2-chloroethyl ethyl sulfide (CEES, SM analog)-poisoned wounds under simulated sunlight (SSL) irradiation. Due to the excellent photothermal detoxification capability possessed by ZnInS/UIO, the conversion rate of CEES can be significantly increased under SSL exposure. When encased in a polyvinyl alcohol (PVA) MNA and piercing into the skin, ZnInS/UIO catalysts can be released quickly from MNA for detoxification. After applying the resultant ZnInS/UIO-MNA to the CEES-poisoned wound bed, acceleration of the wound healing process and a reduced inflammatory response can be confirmed. In conclusion, ZnInS/UIO-MNA has encouraging potential as a first-aid dressing for CEES-poisoned wound healing in battlefields and injuries related to acts of terrorism.

Protection against harmful chemical compounds is a major social concern, especially chemical warfare agents (CWAs) that are easy to synthesize and can cause mass casualties. The metal oxides with large surface area, porous structures, and a large number of active sites have shown outstanding performance for the adsorption and decontamination of CWAs. However, single-component metal oxides show a lower degradation rate for chemical warfare agents. Here, we demonstrate a convenient homogeneous hydrolysis method for the synthesis of mesoporous manganese-based multi-component metal oxides. Our strategy enables Ce or/and Zr to be doped into the δ-MnO 2 structure during the forming process, remarkably enlarging the surface area and providing rich active sites for CWA catalysis. The as-synthesized multi-component metal oxides exhibit excellent performance for the CWA degradation. It is surprising to find that the best degree of removal of mustard gas (HD), soman (GD), and the VX nerve agent (VX) is 90.60%, 87.32%, and 100%, respectively, reaction with multi-component samples in 4 h, 2.92-fold increase to HD, 8.28-fold increase to GD, and 1.67-fold increase to VX contrast with undoped δ-MnO 2 . This work may provide an avenue for developing new generation chemical warfare agent decontamination materials and other catalysts.

Conventional methods for the detection of the sulfur mustard poisoning metabolic marker, thiodiglycol (TDG), require expensive instruments and reagents as well as professional operators. To address these problems, a novel test strip based on a molecularly imprinted sensitive membrane (MIM) was developed in this work for point-of-care (POC) detection of TDG. The TDG test strip was prepared conveniently by coating molecular imprinted polymers (MIPs) on a nitrocellulose membrane. When the sample contained TDG, the MIPs could specifically bind with TDG. A great number of AuNPs (AuNPs) could then be adsorbed on the test strip via the formation of an Au–S bond between TDG and AuNPs, giving the test strip the obvious red color of AuNPs. In the absence of TDG, the test strip exhibited much lighter color because it could not adsorb AuNPs. By monitoring the color change of the test strip, TDG could be detected from 1.0 ng/mL to 100.0 μg/mL with a detection limit of 0.23 ng/mL (3σ) under the optimal conditions (the molar ratio of TDG to MAA was 1:2; the eluent was chloroform; the elution time was 50 min; the reaction time between MIPs and TDG was 15 min; the adsorption time of AuNPs was 40 min; the temperature of the reaction system was 35 °C). This method has excellent selectivity and has been used to detect TDG in urine, showing great potential for POC detection of TDG in clinical samples.

Chemical protective clothing is crucial for shielding operators from toxic and hazardous substances. However, the limited moisture permeability of these garments significantly affects worker comfort and functionality over long periods. In this study, we introduce a novel graphene oxide/polyurethane composite membrane with an innovative alternating layer structure and improved interlayer bonding, produced through a simple, scalable layer-by-layer assembly method. The outstanding L-GO/PU membrane offers robust chemical protection for up to 24 h against harmful agents like mustard gas and dichloromethane, while also showing excellent resistance to both acidic and alkaline solutions. With a moisture permeability of 3116 g m −2 d -1 , this membrane ensures optimal comfort during extended use. Additionally, it demonstrates remarkable resistance to swelling, maintaining its structural integrity for 27 days during prolonged immersion in water. The L-GO/PU composite stands out as an excellent choice for chemical protective gear, combining high toxicity resistance with superior moisture management capabilities.
