We investigated the visible-light sensitive photocatalytic ability of a designed ternary Pd-GO/TiON nano-composite for use as an effective photocatalyst in membranes. We succeeded in synthesizing the TiO2-based photocata-lyst for Suzuki coupling reaction and application of this photocatalyst for fabricating high performance photocatalytic membrane. In this regard, palladium metal as a complementary metal in combination with N-doped TiO2 (TiON) and graphene oxide (GO) nanosheets was utilized to synthesize the upgraded version of the visible light sensitive nanocom-posite photocatalyst. The synthesis of Pd-GO/TiON hierarchical nanostructure was confirmed by detecting Ti, Pd, C, O and N elements by X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray (EDX) and EDX mapping analysis. Then, a series of PVDF-based photocatalytic nanocomposite membranes (PhNMs) filled with Pd-GO/TiON was fabricated. Evaluating the yield of Pd-GO/TiON photocatalyst was around 99% and 70% for heterogeneous system and the prepared PhNM containing 3% Pd-GO/TiON, respectively. Although, yield of Pd-GO/TiON photocatalyst in membrane is not comparable with the high yield reported by other researchers in heterogeneous system; however, it can be considered as a valuable result because of the importance of photocatalytic reactions and the environmental advantages of membrane technology. Furthermore, various analyses were also performed to study the synthesized photocata-lysts and the prepared photocatalytic membranes, including thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and diffuse reflectance spectrophotometry (DRS).

一种用于纳米复合膜的新型三元 Pd-GO/N 掺杂 TiO2 分级可见光敏感光催化剂

我们研究了设计的三元 Pd-GO/TiON 纳米复合材料用作膜中有效光催化剂的可见光敏感光催化能力。我们成功合成了用于铃木偶联反应的 TiO2 基光催化剂，并将该光催化剂用于制备高性能光催化膜。在这方面，钯金属作为互补金属与 N 掺杂的 TiO2 (TiON) 和氧化石墨烯 (GO) 纳米片相结合，用于合成升级版的可见光敏感纳米复合光催化剂。通过 X 射线光电子能谱 (XPS)、能量色散 X 射线 (EDX) 和 EDX 映射分析检测 Ti、Pd、C、O 和 N 元素，证实了 Pd-GO/TiON 分层纳米结构的合成。然后，制备了一系列填充有 Pd-GO/TiON 的基于 PVDF 的光催化纳米复合膜（PhNMs）。评估 Pd-GO/TiON 光催化剂的产率对于非均相系统和制备的含有 3% Pd-GO/TiON 的 PhNM 分别约为 99% 和 70%。尽管膜中Pd-GO/TiON光催化剂的产率与其他研究人员报道的非均相系统的高产率不相上下；然而，由于光催化反应的重要性和膜技术的环境优势，它可以被认为是一个有价值的结果。此外，还进行了各种分析以研究合成的光催化剂和制备的光催化膜，包括热重分析 (TGA)、扫描电子显微镜 (SEM)、
