Abstract

Samarium oxide-decorated on zinc oxide nanorods (Sm₂O₃@ZnONRs) nanohybrid was prepared using the microwave-assisted hydrothermal (MW-HT) method and utilized for the visible light (VL) driven photo-oxidtion of flavonoid (MR: morin). It exhibits optical energy gap (E_g) ca. ∼2.57 eV compared to ZnONRs (E_g: ∼3.25 eV). The reduced E_g of nanohybrid is favourable for the VL harvesting and the tight interface of Sm₂O₃ and ZnONRs strengthen the transfer and mobility of charge carries, leading to the high resistance to the recombination of photo-induced electron (h⁺/e⁻) pairs. Particularly, the nanohybrid yielded 98.8 % degradation of MR in 60 s and the rate constant (k) 0.0244 s⁻¹, which was 3.2, 2.9, and 1.9 times faster than commercial ZnO, Sm₂O₃, and ZnONRs. The significant MR photo-oxidation can be related to synergetic effect and the inhibition of charge–carrier recombination system. Moreover, the good results provide an important guidance for the various flavonoids oxidation applications.

微波辅助水热合成Sm2O3@ZnO光氧化类黄酮纳米杂化物

采用微波辅助水热法（MW-HT）制备了氧化锌纳米棒（Sm2O3@ZnONRs）上的氧化钐纳米杂化物，并将其用于可见光驱动的类黄酮（MR: morin）光氧化。与znonr （Eg: 3.25 eV）相比，它具有约2.57 eV的光能隙（Eg）。还原后的Eg有利于VL的收获，Sm2O3和ZnONRs的紧密界面增强了载流子的转移和迁移率，从而对光诱导电子（h+/e−）对的重组具有高电阻。特别是，纳米杂化物在60 s内降解率达到98.8%，速率常数(k)为0.0244 s−1，比商用ZnO、Sm2O3和ZnONRs分别快3.2、2.9和1.9倍。显著的MR光氧化可能与协同效应和对载流子复合体系的抑制有关。研究结果对黄酮类化合物的各种氧化应用具有重要的指导意义。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
