A cubic Ti-MOF ([Ti2-(TpA)2-H2BIPA]), constructed from a titanium metal center and a benzo-imidephenanthroline tetracarboxylic acid (H4BIPA-TC) ligand was photo-inductively grown on the surface of a titanium dioxide (TiO2) composite optical waveguide (COWG) substrate and the influence of photo-inductive growth period on the [Ti2-(TpA)2-H2BIPA] film surface morphology, optical properties and gas adsorption/sensing characteristics was investigated. The results showed that [Ti2-(TpA)2-H2BIPA] formed a cubic structure after grew for only 5 minutes. As an ideal gas adsorbent, it exhibits a specific response to ethylenediamine (EDA) among various benzene, amine and acid gases, due to the intrinsic electron deficiency, rich COOH active sites of the Ti-BIPA-TC-MOF-5 frame and the higher molar refractive indexes (RDs) or dipoles of EDA than other gases. In the EDA concentration range from 10 ppt to 100 ppm, the Ti-BIPA-TC-MOF-5 film COWG exhibited a rapid, repeatable response. Moreover, the Ti-BIPA-TC-MOF-5 film COWG was relatively stable, within 17 days of EDA detection, the response intensity was almost constant and slightly decreased within 40 days. In a static gas adsorption stage at 283-313 K, the EDA gas adsorption behaviour of the Ti-BIPA-TC-MOF-5 film is consistent with the pseudo-second-order (PSO) kinetic model.

“…EDA vapors can invade the body through the respiratory system and skin, thus causing serious health problems such as conjunctivitis, pneumonia, contact dermatitis, asthma, liver and kidney dysfunction, and even tumors [4,5]. The permissible concentration-short term exposure limit (PC-STEL) for EDA is 10 ppm [6]. Therefore, achieving real-time, effective detection and monitoring of EDA is essential to production life safety.…”

An ethylenediamine (EDA) gas sensor based on a composite of MoO3 nanoribbon and reduced graphene oxide (rGO) was fabricated in this work. MoO3 nanoribbon/rGO composites were synthesized using a hydrothermal process. The crystal structure, morphology, and elemental composition of MoO3/rGO were analyzed via XRD, FT-IR, Raman, TEM, SEM, XPS, and EPR characterization. The response value of MoO3/rGO to 100 ppm ethylenediamine was 843.7 at room temperature, 1.9 times higher than that of MoO3 nanoribbons. The MoO3/rGO sensor has a low detection limit (LOD) of 0.235 ppm, short response time (8 s), good selectivity, and long-term stability. The improved gas-sensitive performance of MoO3/rGO composites is mainly due to the excellent electron transport properties of graphene, the generation of heterojunctions, the higher content of oxygen vacancies, and the large specific surface area in the composites. This study presents a new approach to efficiently and selectively detect ethylenediamine vapor with low power.

The niobium metal–organic framework (Nb‐MOF = [Nb2(bdc)2(NDI)]n) membrane, constructed from terephthalic acid(bdc) and 1,8,4,5‐naphthalenetetracarboxdiimide (NDI), is in this work grown on the surface of lithium niobate (LiNbO3) film composite optical waveguide (COWG) substrate using UV‐light illumination method. After growing for 20 min, the Nb‐MOF membrane forms as a graphene‐like structure with 50 nm pore size and 96 nm thickness. At room temperature (25 °C), in terms of COWG sensors, Nb‐MOF exhibits the greatest response to H2S and SO2, followed by ethylenediamine (EDA) and NO2, coexistence with 15 kinds of benzenes, amines, and acidic gases. In order to improve its response selectivity, the spirooxazine (SP) is embedded into the Nb‐MOF frame, and a SP@Nb‐MOF membrane COWG with smooth‐snowflake imprinted surface is obtained. In gas sensing performance, the obtained COWG shows the greatest response to H2S, while the response of SO2, NO2, and other gases are obviously diminished. When the SP@Nb‐MOF membrane exposes to H2S gas, proton‐transfer and morphology modulation are induced. The presented sensor also shows a wide detection range (1 × 104–0.1 ppb), fast response (4 s), and long‐term stability of 120 d to H2S at room temperature (25 °C) and 25% relative humidity.
