本研究中,二硫化鉬奈米花(MoS2 NFs)包覆金奈米粒子(Au NPs)的異質結構在可見光照射與聲波處理下,已被證實它可以增強壓電光催化氫析出反應之活性。二硫化鉬由於其較窄的能帶隙而顯示出顯著的光催化性能,並且在其邊緣部位擁有獨特的壓電性質。在此,電子和電洞高複合速率以及缺少活性位點等限制氫氣釋放效率的問題,可通過將金奈米顆粒引入二硫化鉬奈米花中解決。而該異質結結構可以通過簡單的水熱過程合成。在基於光致發光(PL)光譜的結果中,證實金奈米粒子@二硫化鉬奈米花可達到減少電子和電洞再結合的可能性。通過氣相層析(GC)分析,金奈米粒子@二硫化鉬奈米花的析氫性能為與原始二硫化鉬比較之161%以上。於紫外可見(UV-Vis)光譜儀的吸收光譜和表面增強拉曼散射(SERS)光譜所觀察,顯著改善主要來自於壓電效應誘導局部表面等離子體共振(LSPR)效應的熱電子。為了進一步驗證熱電子的貢獻,更採用了密度泛函理論(DFT)和有限元素法(FEM)等計算方法來模擬電場分佈。局部表面等離子體共振增強壓電光催化氫釋放的機理將被研究與探討。
This work, Au nanoparticles covered by MoS2 nanoflowers (referred to Au NPs@MoS2 NFs here forth) heterostructure sonicated with visible light irradiation, has been confirmed it can enhance the piezo-photocatalytic activity for hydrogen evolution reaction. MoS2 displays prominent catalytic properties due to its abundant active edge sites and obsesses unique piezoelectricity in a few-layered structure. Herein, the high rate of electrons and holes recombination and lack of active sites that limit the efficiency of hydrogen evolution reaction have been resolved by introducing gold nanoparticles into MoS2 nanoflowers. The heterojunction structure could be synthesized by a facile hydrothermal process. Based on the photoluminescence (PL) spectrum, Au NPs@MoS2 NFs achieve to reduce the recombination possibility. Through gas chromatography (GC) analysis, the hydrogen evolution of Au NPs@MoS2 NFs shows over 161% better than pristine MoS2. The significant improvement mainly arises from piezoelectricity inducing hot electron of localized surface plasmon resonance (LSPR) effect as observed by the absorption spectrum of ultraviolet-visible (UV-Vis) spectrophotometer and surface enhanced Raman scattering (SERS). For further verifying the contribution of hot electrons, density functional theory (DFT), and finite element method (FEM) was employed to simulate the charge distribution. The mechanism on LSPR enhanced piezo-photo catalytic hydrogen evolution will be investigated.
