Localized Surface Plasmon Resonance Enhanced Photocatalytic Activity via MoO2/BiOBr Nanohybrids under Visible and NIR light

Abstract: Direct efficient employing of solar energy for environmental treatment is obtaining considerable attention at present, where the efficient utilizing the visible (Vis) and near‐infrared (NIR) light is of utmost importance. Herein, the plasmonic MoO2 has been firstly employed to enhance photocatalytic activity in visible and near‐infrared light. By loading MoO2 on BiOBr nanosheets, the plasmonic MoO2/BiOBr photocatalysts have been designed and synthesized through simple hydrothermal method. Localized surface pla… Show more

“…As shown in Figures a,b and S4, the Fermi level of MoO 2 enters the conduction band level, and no distinct gaps are observed between the conduction and valence bands. This is consistent with the results reported in previous literatures. , Moreover, the DOS crosses the Fermi energy, which indicates that both MoO 2 and Mo/MoO 2 present metallic behavior. The metallicity of MoO 2 mainly comes from Mo 3d orbitals with a high density of free d electrons.…”

“…The tight contact between CZS and Co–WS 2 is significant to promote the separation and transfer of photogenerated electrons and holes. [ 33 ] The elemental mapping images of the 7% (Co–WS 2 )/CZS sample are shown in Figure 2d–i; Cd, Zn, S, W, and Co elements are homogeneous distribution over the entire area of the 7% (Co–WS 2 )/CZS sample, indicating the uniform loading of the CZS nanoparticles on the surface of Co–WS 2 and no other impurity substances existing in the composite. [ 34 ] The concentration of Co is 0.093 mg L −1 by inductively coupled plasma optical emission spectrometer (ICP–OES) measurement (Table S2, Supporting Information).…”

“…At the same time, MoO 2 nanomaterials have remarkable thermal and chemical stability . Notably, the high concentration of free electrons and low resistivity of MoO 2 make them have a strong LSPR effect . The doping of oxygen vacancies and loading of metal nanoparticles will promote charge transfer and improve the LSPR effect of MoO 2 . ,, Controlled doping in semiconductors is of vital importance in developing novel materials. Moreover, interface engineering is of crucial significance for functional devices. Therefore, it is desirable to design a facile method to localize the defects and metal catalytic centers in MoO 2 .…”
