The attention toward cost-effective and high-performance H2S sensors is increasing due to the growing need for physical health environmental monitoring. In this paper, Ag/WO3/reduced graphene oxide (rGO) nanocomposites were synthesized by using a microwave-assisted gas–liquid interfacial method. Nanomaterials with different Ag doping contents successfully prepared AgNO3 as an additive. Ag/WO3/rGO exhibit remarkable selectivity H2S, gas sensing performances of Ag-doped WO3/rGO are significantly better than those WO3/rGO. At 150 °C, response value 10 wt % sensor 100 ppm 204.5, which 7 times higher that WO3/rGO, response/recovery time 9/49 s, respectively. Additionally, performance further enhanced under ultraviolet (UV) irradiation. 685.8, 3 without UV irradiation, reduced 8/38 mechanism also discussed. This work offers potential application detection in monitoring smart healthcare.

Abstract Efficient, stable, and inexpensive electrocatalysts are essential to overcome the high overpotential slow kinetics of oxygen evolution reaction (OER) process during water electrolysis applications. 2D transition metal carbides (MXene) show great potential in functional heterogeneous interface engineering for electrocatalytic OER. However, it is still a challenge regulate interlayer space realize layer‐by‐layer ordered embedding MXene. Herein, simple hydrothermal‐assisted strategy proposed prepare highly conductive Ti 3 C 2 T x MXene supported by synergized Ni 2+ , Co Fe 3+ with bilayer H O, which significantly enlarges distances improves ion concentrations. Benefiting from modulated chemistry, embedded ions undergo multi‐directional situ growth on substrate, thereby forming stable 0D/2D@2D nano‐hybrid material (NiFe/MX‐HT). Combining density theory calculations experiments demonstrates that offers framework electron transfer, enhances exposure active sites, modulates electronic structure, greatly reduces energy barrier rate‐determining step Thus, NiFe/MX‐HT requires only 230 mV achieve 10 mA cm −2 maintains stability even after operating at 100 150 h. This work new insights into exploring various MXene‐based materials.
