摘要

采用湿化学技术合成了新型的Pd-Sn双金属纳米颗粒。纳米颗粒在不添加任何添加剂的情况下，以水为溶剂将仲苯甲醇氧化为相应的羰基，表现出优异的催化活性。它也经受住了多次循环而没有失去活性。初步动力学研究表明β-氢化物的消除机制。设计了一种适合实验台的湿化学方法来合成Pd-Sn双金属纳米合金，并通过PXRD、FESEM、HRTEM、UV-Vis、FT-IR、EDAX和ICP-OES进行了表征。该纳米合金在水中具有良好的分散性，可催化高TOF水中仲醇的氧化。

Catalysis via bimetallic Pd-Sn nanoparticles: green oxidation of secondary benzyl alcohol in water in the absence of base

Novel Pd-Sn bimetallic nanoparticles have been synthesized using the wet chemical technique. The nanoparticles show excellent catalytic activity in oxidizing secondary benzyl alcohol to the corresponding carbonyl in water as the solvent without any additive. It also withstood multiple cycles without loss of activity. Preliminary kinetic studies indicate a β-hydride elimination mechanism.

Graphical abstract

A bench-friendly wet-chemical method is designed to synthesize Pd-Sn bimetallic nanoalloys characterized by PXRD, FESEM, HRTEM, UV-Vis, FT-IR, EDAX, and ICP-OES. The nanoalloy is highly dispersible in water and catalyzes the oxidation of secondary alcohols in water with high TOF.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
