使用还原氧化石墨烯（rGO）作为模板，通过高温溶胶-凝胶化学，我们制备了LaFeO 3纳米颗粒（NPs）。15 nm的LaFeO 3纳米颗粒具有1.86 eV的带隙和LaFeO 3-rGO可以作为一个有效的催化剂降解亚甲基蓝（MB）或罗丹明B（Rh B）在可见光照射下，从染料的电子转移到空穴占主导地位的氧化过程。报道的合成提供了一种用于高效光催化应用的钙钛矿型纳米颗粒的通用方法。
Using reduced graphene oxide (rGO) as a template and high temperature sol-gel chemistry, we have prepared LaFeO3 nanoparticles (NPs). The 15 nm LaFeO3 NPs have a bandgap of 1.86 eV and the LaFeO3-rGO can function as an efficient catalyst for degradation of methylene blue (MB) or Rhodamine B (RhB) under visible-light irradiation with the electron transfer from the dye to hole dominating the oxidation process. The reported synthesis offers a general approach to perovskite-type NPs for efficient photocatalytic applications.
