In an effort to develop a long-lasting gas sensor, this article presents titanium nitride (TiN) as a potential substitute sensitive material in conjunction with (copper(II) benzene-1,3,5-tricarboxylate) Cu-BTC-derived CuO. The work focused on the gas-sensing characteristics of TiN/CuO nanoparticles in detecting HS gas at various temperatures and concentrations. XRD, XPS, and SEM were utilized to analyze the composites with varied Cu molar ratios. The responses of TiN/CuO-2 nanoparticles to 50 and 100 ppm HS gas at 50 °C and 250 °C are 34.8 and 60.0, respectively. The related sensor had high selectivity and stability towards HS, and the response of TiN/CuO-2 is still 2.5-5 ppm HS. The gas-sensing properties as well as the mechanism are fully explained in this study. TiN/CuO might be a choice for the detection of HS gas, opening up new avenues for applications in industries, medical facilities, and homes.

The synthesis of biomass-derived nanocarbons via ball milling has emerged as an innovative, sustainable, and cost-effective strategy in the field of nanotechnology. This review comprehensively explores the principles, mechanisms, and process parameters that influence the production of high-quality nanocarbons from biomass using ball milling. This process efficiently transforms biomass residues into nanoscale carbon, including graphene, carbon nanotubes, and nanofibers, with tunable physicochemical properties tailored for advanced applications.

Layered double hydroxides (LDHs) have attracted considerable attention in gas sensing applications due to their highly tunable chemical composition and unique two-dimensional layered architecture. In this study, a series of ZnAl-LDHs with varying Zn/Al molar ratios were synthesized a facile hydrothermal method, and their ethanol sensing performance at room temperature was systematically evaluated. The influence of composition on the structural, morphological, and electronic properties of the materials was thoroughly investigated using a suite of characterization techniques, including XRD, FTIR, SEM, TEM, BET, XPS, PL, and EPR.

Nanogranular films obtained by the soft assembly of atomic clusters feature functional properties that are of interest in a variety of fields, ranging from gas sensing to neuromorphic computing, heterogeneous catalysis and the biomedical sector. Bimetallic nanogranular films, combining a post-transition metal (tin) and a catalytic metal (platinum), were produced using supersonic cluster beam deposition. By operating the cluster source with a double-rod cathode or sintered cathode configuration, completely different nanostructures were obtained.

The exceptional electronic properties, high surface area, and structural versatility of two-dimensional materials make them excellent candidates for gas-sensing applications. In this study, we propose novel biphenylene (b) and graphenylene (g) lattices of ZnCdO and explore their potential for detecting NO and SO gases via density functional theory calculations. The dynamic and thermal stability of b-(g)-ZnCdO monolayers is confirmed through phonon dispersion and ab initio molecular dynamics simulations.

Herein, tungsten-doped nickel titanate (WNiTiO3) nanoparticles are synthesized using hydrothermal route and investigated physicochemical and gas sensing properties. The effect of W-dopant concentrations on the physicochemical and electrical characteristics of NiTiO3 is systematically investigated. X-ray diffraction analysis revealed a consistent decrease in crystallite size, accompanied by an increase in dislocation density and micro-strain with higher W doping levels.
