Smart sensors capable of detecting NH3 at sub-ppb levels are important for human health in our daily life. Here, we demonstrate a surface acoustic wave (SAW) sensor based on ZnO@MXene hybrid heterostructure ultrahigh gas detection under UV illumination room temperature (RT). Under illumination, the SAW not only significantly enhances frequency response (Δf ≈ 32.24 kHz/20 ppm) but also effectively improves selectivity with low limit (89.41 ppb), short response/recovery times (92/104 s),...
Abstract An n-p type homostructural metal-free graphitic carbon nitride (g-C 3 N 4 ) semiconductor is designed and developed for pollutant abatement energy storage application. The successful grafting of vibrio-like morphology-based g-C by 2, 5-Thiophenedicarboxylic acid (TDA) molecule the development amide-type linkage substantiated prosperous uniting with organic TDA moiety demonstrated. extended π-conjugative grafted exhibited band gap tunability broadband optical absorbance in visible...
Vanadium oxides (VxOy) are classic “smart functional materials” used in a wide array of thermochromic, electronic, and catalytic applications. Specifically, vanadium dioxide (VO2) class nanomaterials enormous interest due to their unique first order reversible metal-insulator phase transition (MIT) behavior accompanied by structural transition, inducing dramatic changes electrical optical properties with large lattice deformation. To date, plethora reports exemplifying the MIT...
Metal-free polymeric carbon nitride (PCN) materials are at the forefront of photocatalytic applications. Nevertheless, overall functionality and performance bulk PCN limited by rapid charge recombination, high chemical inertness, inadequate surface-active sites. To address these, here, we employed potassium molten salts (K+X-, where X- is Cl-, Br-, I-) as a template for in situ generation surface reactive sites thermal pyrolyzed PCN. Theoretical calculations imply that addition KX to...
Abstract Mixed tin–lead perovskites suffer from structural instability and rapid tin oxidation; thus, the investigation of their optimal composition ranges is important to address these inherent weaknesses. The critical role triple cations in mixed Sn–Pb iodides studied by performing a wide range compositional screenings over mechanochemically synthesized bulk solution‐processed thin films. A ternary phase map FA (Sn 0.6 Pb 0.4 )I 3 , MA(Sn Cs(Sn formed, promising window (FA 0.6− x MA Cs )Sn...
Molecular engineering of graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) is achieved by the copolymerization π-conjugated phenyl urea, melamine, and urea.
The utilization of the dielectric barrier discharge (DBD) plasma process presents a promising avenue for transforming carbon dioxide (CO2) into valuable compounds. In this research, we explore integration DBD with NiOx/γ-Al2O3 catalyst to amplify efficiency and selectivity conversion CO2 monoxide (CO). A series NiOx-loaded on γ-Al2O3 catalysts were synthesized through wet impregnation employed in reactor. synergy between nonthermal resulted significant enhancement conversion, particularly...
Abstract All‐perovskite tandem solar cells have garnered considerable attention because of their potential to outperform single‐junction cells. However, charge recombination losses within narrow‐bandgap (NBG) perovskite subcells hamper the advancement this technology. Herein, we introduce a lithium salt, bis(trifluoromethanesulfonyl)imide (LiTFSI), for modifying NBG perovskites. Interestingly, LiTFSI bifunctionally passivates surface and bulk by dissociating into Li + TFSI − ions. We found...
