Single atomic and diatomic catalysts have been extensively studied as electrocatalysts for the oxygen evolution reduction reactions (OER ORR) in recent years. It was found that interfacial chemistry between hydroxyl groups had a profound influence on electrochemical reaction process. In this work, we carried out systematic density functional theory (DFT) studies electrocatalytic process of OER ORR under alkaline conditions over group modified single metal atom (M = Ni, Co, Fe) bi-metal atoms...
Detection of ultralow concentrations ammonia is very important in many applications such as fishing, poultry, agriculture, industry, biomedicine, and clinical diagnosis. However, detecting sub-ppm NH3 remains a challenge for chemiresistive-type gas sensors. Two-dimensional (2D) materials display tremendous potential effective detectors that can be used these applications. The as-developed MXene/SnS2 heterojunction-based sensor presents superior gas-sensing performance toward at room...
Hollow In2O3@TiO2 double-layer nanospheres were prepared via a facile water bath method using the sacrifice template of carbon nanospheres. It is shown that size In2O3/TiO2 nanocomposites 150-250 nm, thickness In2O3 shell about 10 and TiO2 15 nm. The sensing performances synthesized nanocomposites-based chemiresistive-type sensor to formaldehyde (HCHO) gas under UV light activation at room temperature have been studied. Compared pure In2O3- TiO2-based sensors, nanocomposite exhibits much...
Abstract Graphene‐based heterostructure composite is a new type of advanced sensing material that includes composites graphene with noble metals/metal oxides/metal sulfides/polymers and organic ligands. Exerting the synergistic effect ligands way to design gas sensors for nitrogen‐containing species including NH 3 NO 2 solve problems such as poor stability, high working temperature, recovery, selectivity. Different fabrication methods graphene‐based are extensively studied, enabling massive...
In this work, MXene/NiO-composite-based formaldehyde (HCHO) sensing materials were successfully synthesized by an in situ precipitation method. The heterostructures between the MXene and NiO nanoparticles verified transmission electron microscopy (TEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS). HCHO performance of MXene/NiO-based chemiresistive-type sensors was investigated. Compared to pure materials, MXene/NiO-P2-based sensor gas at room temperature significantly enhanced...
Rationally designed conductive hierarchical nanostructures are highly desirable for supporting pseudocapacitive materials to achieve high-performance electrodes supercapacitors. Herein, manganese molybdate nanosheets were hydrothermally grown with graphene oxide (GO) on three-dimensional nickel foam-supported carbon nanotube structures. Under the optimal concentration, obtained nanotubes/reduced oxide/MnMoO4 composites (CNT/rGO/MnMoO4) as binder-free supercapacitor cathodes perform a high...
