Sulfur dioxide (SO2) is one of the most hazardous and common environmental pollutants. However, development room-temperature SO2 sensors seriously lagging behind that other toxic gas due to their poor recovery properties. In this study, a light-assisted sensor based on polyaniline (PANI) Ag nanoparticle-comodified tin nanostructures (Ag/PANI/SnO2) was developed exhibited remarkable sensitivity excellent The response Ag/PANI/SnO2 (20.1) 50 ppm under 365 nm ultraviolet (UV) light illumination...
To address the challenge of rapid detection trace amounts NH3 at room temperature, gas sensor based on PANI/g-C3N4 (graphitic carbon nitride) nanocomposite was fabricated via hydrothermal exfoliation g-C3N4 combined with in situ oxidative polymerization PANI. The test results demonstrated that 30 mol % nanosheet-doped PANI hybrid (PCN (30)) exhibited highest sensitivity to NH3. sensing response PCN (30) (19.53) 200 ppm improved by 50% compared pure (12.99) and reached ppb-level limit 25 °C....
Sulfur dioxide is one of the most hazardous and toxic air pollutants. Herein, S-doped SnO2 material (S-SnO2) was successfully recovered from tin sludge that an important secondary resources with a tremendous output high oxide content. After dispersion Ag modification S-SnO2, as-prepared Ag/Ag2S-doped S-SnO2 (Ag/Ag2S/S-SnO2) showed excellent sensing performance toward SO2. The morphology, structure, surface state materials were performed by X-ray diffraction (XRD), scanning electron...
The Cu-loaded polyaniline-coated MoO3 nanowire ternary nanohybrids were successfully prepared by the solution heat method and in situ oxidation polymerization for traces of ammonia (NH3) detection at room temperature. placed on fork finger electrode alumina substrate a spin coating method. gas sensitivity devices to NH3 was evaluated static results showed that sensor based Cu-3-PMN-20 nanohybrid (doping 20 wt % nanowires loaded 3 nano Cu PANI) exhibited best (17.11), which 6 times higher...
Device stability is the most important issue that hinders perovskite solar cell (PSC) commercialization, given achieved efficiency of PSC exceeds 23%. The materials and contact layers throughout device stack are scrutinized with regard to stability, but research has mainly focused on examination long‐term behavior. Herein, impacts short‐term PSCs, which always overlooked, investigated. PSCs correlated additives solution‐processed hole‐transport layer. These exert a critical impact underneath...
Solution-processed 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine) 9,9′-spirobifluorene [spiro-OMeTAD] material was employed as the hole-transport layer that is widely used in solid-state dye-sensitized and perovskite solar cells. The electrical optical properties of spiro-OMeTAD single crystals are still ill-defined. Here, we an antisolvent vapor-assisted crystallization method to grow up several millimeters. different presented, compared with powder film. Our investigation provides a...
Mesoporous n-i-p perovskite solar cells (PeSCs) demonstrate attractive potential for obtaining high power conversion efficiencies (PCEs), by employing inorganic electron transport layers (ETLs). However, these ETLs composed of dual (a condense layer and a mesoporous layer) suffer the composite process sintering temperature. Here, we simple efficient to improve device performance PeSCs using textured SnO2 film. Self-aged sol-gel solution after spin coating results in structure without...
