Abstract
Abstract null null In this work, the hybridization of Co(Ⅲ) doped-CoFe layered double hydroxide and graphene oxide (CoFe LDH/GO) was first employed as catalyst to establish a cataluminescence (CTL) gas sensor for detection of carbon monoxide. In order to obtain Co(Ⅲ) doped-CoFe LDH/GO with the best CTL performance, synthesis reaction parameters including amount of oxidant, oxidation time and amount of GO were studied. The structure and morphology of Co(Ⅲ) doped-CoFe LDH/GO were characterized. The Co(Ш) doped-CoFe LDH/GO based CTL sensor enabled the selective determination of carbon monoxide with signal response of 0.5 s and restores of 1.0 s. The RSD was 5.6% and CTL intensity remained stable within 10 days. The calibration curve of carbon monoxide is linear in concentration range of 0.01–20 mg/L and the limit of detection(LOD)is 0.002 mg/L. Comparing with the reported CTL sensor, the Co(Ш) doped-CoFe LDH/GO based CTL sensor shows wide linear range, low LOD and use little assistive technology. Carbon monoxide in automobile exhaust was quantified with recoveries of 92.0% to 108.0%. The analytical results were agreed well with gas chromatography method. This work designed high performance catalytic materials for CTL detection of carbon monoxide.

Abstract Cheap sensors are necessary for detection of automotive exhaust gas pollutants, to diagnose the fuel injector, engine and catalytic converter performances. SnO2 and Pt/SnO2 sensors reduced in CO were used for highly sensitive and selective detection of CO as the major pollutant in automotive exhaust gases. SnO2 was prepared by a sol-gel method, on which Pt nanoparticles were deposited by an impregnation method. The sensors were reduced in 1%CO in Ar at 300, 400 and 500°C for 1.5 h and c...

The freshness of meat has always been the focus of attention from consumers and suppliers for health and economic reasons. Usually, amine vapors, as one of the main components of the gas produced in the process of meat spoilage, can be used to monitor meat spoilage. Here, a new ratiometric cataluminescence (CTL) sensor based on energy transfer was developed to identify amine vapors and monitor meat freshness. After Tb doping, amine vapors exhibit a dual-wavelength (490 and 555 nm) property of CT...

Abstract As a highly toxic gas, hydrogen sulfide (H2S) poses risks in terms of environmental and human health. It is mandatory to investigate sensing materials for high performance H2S sensing. Compared with typically metal materials, metal-free materials show significant advantages in its low-cost, environmentally friendliness as well as stability, which attract more and more attentions in recent years. In this study, with Zinc (Zn) salt as a co-reagent, a two-dimensional metal-free material, p...

Abstract The global outbreak of coronavirus disease and rapid spread of the causative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represent a significant threat to human health. A key mechanism of human SARS-CoV-2 infection is initiated by the combination of human angiotensin-converting enzyme 2 (hACE2) and the receptor-binding domain (RBD) of the SARS-CoV-2-derived spike glycoprotein. Despite the importance of these protein interactions, there is still insufficient detection me...

Abstract Aminated graphene oxide (NGO) was synthesized by condensation of graphene oxide (GO) and diethylenetriamine (DETA). Highly catalytic nanostructured NGO-TiO2 composite catalysts were self-assembled by a two-phase system of toluene and water. The crystal structure, morphology, and optical properties of the composite catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible spectrometry (UV-Vis) and so on. The degradation of methyl ora...

Carbon monoxide (CO) has long been known as a "silent killer" because of its ability to bind hemoglobin (Hb), leading to reduced oxygen carrying capacity of Hb, which is the main cause of CO poisoning (COP) in humans. Emerging studies suggest that mitochondria is a key target of CO action that can impact key biological processes, including apoptosis, cellular proliferation, inflammation, and autophagy. Despite its toxicity at high concentrations, CO also exhibits cyto- and tissue-protective effe...

Cataluminescence is an attractive oxydic luminescence on the gas-solid interface, and metal-oxide@MOF core@shell architectures show great potential for cataluminescence sensing due to their integrated synergistic effect from core and shell components. However, restricting the direct nucleation and growth of metal-organic frameworks (MOFs) on the topologically distinct surface of metal oxides is a great challenge, owing to the high interface energy from the topology mismatch. Herein, for the firs...

Background To investigate the protective effect of recombinant human brain natriuretic peptide (rhBNP) on myocardial injury after acute carbon monoxide poisoning (ACOP). Methods We retrospectively reviewed medical records of patients with ACOP and high risk of cardiac events admitted to our hospital, and grouped them into rhBNP group and control group according treatments they received. Patients in control group received conventional treatment while those in rhBNP group were treated with rhBNP i...

Abstract In this work, a novel cataluminescence(CTL) strategy was developed for fast differentiation of sunscreen cosmetics. The CTL reactions occurring on the surface of sunscreen cosmetics whose characteristic composition served as catalyst. Normalization methodology was utilized to process sensor array signals, we developed a dimensionless quantity called “relative signal (Skr)” to characterize the sensor response. Firstly, aldehydes are eligible for triggering CTL reactions on the surface of...

ABSTRACT Electrocatalytic and plasma-activated processes receive increasing attention in catalysis. Density functional theory (DFT) calculations are state-of-the-art tools for the fundamental study of reaction mechanisms and predicting the performance of catalytic materials. Proper application of DFT-based methods is crucial when investigating charge-doped electrode surfaces during electrocatalytic and plasma-activated reactions. Here, as a model electrode for plasma-activated CO2 splitting, we ...
