Abstract High surface area, suitable pore size distribution and good wettability of carbonaceous materials are crucial for a variety of surface and interfacial interaction-related applications. Herein, hydrophilic porous carbon nanosheet with an ultrahigh surface area (4482 m2 g−1) was prepared using lotus leaf (LL) as the carbon source. It was revealed that the surface area and microporosity are dependent on the reactivity of the precursor, which can be characterized by the sp2 hybridized carbo...

Abstract Molybdenum trioxide (MoO3) is an important oxide semiconductor with a broad range of potential applications in electronics, catalysts and gas sensors. Experimentally, it has been demonstrated that MoO3 exhibits ultrahigh sensitivity and selectivity towards trimethylamine (TMA) detection, but the physical mechanism remains elusive. In this work, by using density functional theory based first-principles calculations, we systematically investigated the geometric, energetic and electronic p...

Abstract Photodetectors based on organic-inorganic hybrid are promising which can combine the merits like function tunability of organic materials as well as broadband absorption, excitonic mechanisms and high carrier mobility of inorganic materials. Flexible thin film photodetectors based on inorganic WSe2 nanosheets and organic PANI by tuning composition are developed by simple, cost effective solution blending process. The fabricated hybrid thin films on filter paper substrate manifest visibl...

Abstract We present a study on the synthesis of multi-layer graphene using carbon ion implantation on thin cobalt (Co) films. Carbon ions were bombarded at 20 keV and doses of 4 × 1015 cm−2 and 8 × 1015 cm−2 onto the surface of a Co/SiO2/Si substrate. This process was followed by heat treatment (500–900 °C) to form graphene on Co film. The effects of the heating conditions were systematically investigated by micro-Raman spectroscopy and transmission electron microscopy. The result proved that mu...

Abstract Electroreduction of N2 into NH3 (NRR) under ambient conditions is an attractive alternative compared to the Haber-Bosch process. However, high activity catalyst is still desired for N2 fixation. Herein, we report for the first time nonmetal phosphorus cation (P) is an effective dopant to enhance NRR performance of TiO2. In 0.1 M LiClO4, P-doped TiO2 nanorods lead to excellent NRR performance with a highest FE of 12.26% and a larger NH3 production rate of 23.05 µg h−1 mgcat. −1. Density ...

Abstract The novel V2CTx MXenes have gained increasing attention as anode materials in lithium-ion batteries, but to boost their practical to the theoretical values is still challenging. Herein, the partially etched V2CTx was oxidized in the presence of H2O2 through a hydrothermal reaction and the electrochemical properties of as-obtained oxidized V2CTx were assessed. It is illustrated that the oxidized V2CTx possesses a large surface interlayer spacing, and enriched with VO2 (A) and O-terminate...

Abstract The impact of plasma treatment in the different atmosphere on the surface of the polymer TiO2/PVP microfibers, prepared by needleless electrospinning technology was investigated. The fibers were treated by a low-temperature plasma-induced surface sintering process by a so-called Diffuse Coplanar Srface Barrier Discharge (DCSBD) in three different atmospheres: oxidative – air, reducing – H2 and inert – N2 atmosphere. The impact of the plasma treatment in different atmospheres on the morp...

Abstract Two Co-MOF-74 (Co-MOF-I and Co-MOF–II) were designed for the sensing of H2 gas. Owing to the high density of Co ions (+2 and + 3 states) located in metal clusters in the p-type phase, Co-MOF-74 exhibited better selectivity in gaseous H2 sensing, compared with those of Ni-MOF-74 and Mg-MOF-74. The Co-MOF-II sensor, with higher porosity and Co ion concentration than the Co-MOF-I sensor, had more adsorption sites; consequently, more target gas molecules were adsorbed, resulting in a strong...

Abstract Reported here is a first-principle study of the adsorption of four SF6 decomposition products on pristine arsenene and arsenene with Stone-Wales defects (SW). The results revealed that pristine arsenene exhibited high sensitivity and selectivity to SO2, and Stone-Wales defects enhanced the SO2-sensing performance. The presence of ambient O2, H2O, and SF6 only slightly affected the adsorption on both pristine and SW arsenene. We also investigated the effect of biaxial strain and an exter...

Abstract The reaction mechanism in heterogeneous catalysis which is involving O2 or atomic oxygen has been dicussed intensely because the spin change of O2 molecule and atomic O during the reaction. To understand the mechanism of CO oxidation is key for design of advanced materials. Here we demonstrate spin conversion occurs in the path of CO oxiation on Fe-doped graphene (Fe-Gr) with or without electric field according to our DFT investigations. Moreover, the reations proceed via the similar fa...
