Developing efficient and cheap photocatalysts that are sensitive to indoor light is promising for the practical application of photocatalysis technology. Here, N-doped TiO photocatalyst with loaded Cu crystalline cocatalyst is synthesized by a simple one-pot method. The structure is confirmed by transmission electron microscopy and X-ray photoelectron spectroscopy analysis, which exhibit that Cu metal nanocrystalline is uniformly deposited on the surface of N-doped TiO material. UV-Vis absorption spectra illustrate that the modified samples possess favorable visible light absorption properties and suppressed-electron hole separation. The as-fabricated Cu-loaded N-TiO materials show high activity in photocatalytic decomposing isopropanol and inactivating under the irradiation of a household white LED lamp. The developed synthetic strategy and photocatalytic materials reported here are promising for indoor environment purification.
开发高效且廉价的光催化剂，使其对室内光敏感，这对于光催化技术的实际应用是有前景的。在此，通过简单的一锅法合成了负载 Cu 晶状共催化剂的 N 掺杂 TiO2 光催化剂。通过透射电子显微镜和 X 射线光电子能谱分析对结构进行了确认，结果表明 Cu 金属纳米晶均匀地沉积在 N 掺杂 TiO 材料的表面上。紫外-可见吸收光谱表明，改性后的样品具有良好的可见光吸收性能和抑制电子-空穴分离的能力。所制备的负载 Cu 的 N-TiO 材料在异丙醇的光催化分解和在家庭用白色 LED 灯照射下的失活反应中表现出高活性。这里报道的开发的合成策略和光催化材料有望用于室内环境净化。
