Constructing oxygen vacancies (OVs) in metal-oxide semiconductors is an effective and simple way to enhance the photocatalytic performance via promoting utilization of solar light boosting formation surface reactive species (ROS). The presence different atoms same crystal structure can possibly lead types OVs with distinct physicochemical optoelectronic properties. Particularly, two crystallographic positions [BiO]22+ layer (BiO)2CO3 (BOC) allow construction (OVs1 OVs2). In this work,...
Oxygen vacancies (Ov) as the active sites have significant influences on gas sensing performance of metal oxides, and self-doping Ce3+ in CeO2 might promote formation oxygen vacancies. In this work, hydrothermal process is adopted to fabricate composites graphene nanoparticles, well ions response NO2 are studied. It found that sensitivity increases gradually, proportion relative all cerium increased from 14.6% 50.7% but decreases after value. First-principles calculations illustrate becomes...
Highly exposed active facets and surface oxygen vacancies (OVs) are beneficial for the photocatalytic removal of various harmful organic compounds. In this study, uniform Zn2+-doped BiOI microspheres, assembled by ultrathin nanosheets with highly {001} facets, OVs were successfully synthesized NO under visible light irradiation. The phase structure chemical states analyzed means X-ray diffraction photoelectron spectroscopy, respectively. transmission electron microscopy observations reveal...
VO<sub>2</sub> thin films are prepared on Si substrates by direct-current (DC) magnetron sputtering at room temperature and annealed in vacuum different argon pressures.
Although high-energy facets on metal oxides are usually active and preferred for gas sensing, it is difficult to expose them according thermodynamics. In this work, nanocomposites of SnO2 graphene prepared by a hydrothermal method. The nanoparticles change from lance shape an octahedral as the concentration HCl in solution increased gradually 6.5 10 vol %. However, have elongated if further. mainly surrounded high-surface-energy {221} facets, thus facilitating sensing. First-principles...
Single-layer MoS2 (SLMoS2) nanosheets promise potential applications in flexible electronic and optoelectronic nanodevices for which the mechanical stability is crucial. However, measured fracture strength extremely dispersive, might be due to random crack configuration. In this work, molecular dynamics (MD) simulations are conducted investigate propagation of nanocracks SLMoS2 mechanism at atomic scale, modified Griffith criterion developed by Yin et al. adopted fit dependence stress on...
The CeFCl monolayer is a ferromagnetic bipolar semiconductor with stable semiconducting features and high Curie temperature.
Ferromagnetic (FM) two-dimensional (2D) transition metal dichalcogenides (TMDs) have potential applications in modern electronics and spintronics doping of TMDs with metals can enhance the magnetic characteristics. In this work, structural stability, electronic states, properties Mn-doped monolayer/bilayer MoS2 are studied systematically by first-principles calculations. Substitutional Mn dopants at Mo sites energetically favorable both monolayer bilayer under S-rich condition which is...
