Abstract

Herein, we show the detailed behavior of palladium leaching from palladium on charcoal by aqueous HCl, directly observed by X-ray absorption spectroscopy measurement employing a simplified reaction setup. While Pd is not affected by the addition of HCl, palladium oxide in nanoparticles readily reacts with HCl to form the ionic species [PdCl], even though these ions mostly remain adsorbed on the surface of activated charcoal and can only be detected at a low level in the solution phase. This finding provides a new aspect for control of the leaching behavior and robust usage of palladium on charcoal in organic reactions.

摘要

在此，我们展示了通过采用简化反应装置的X射线吸收光谱测量直接观察到的，盐酸水溶液从载钯炭中浸出钯的详细行为。虽然钯不受盐酸添加的影响，但纳米颗粒中的氧化钯很容易与盐酸反应形成离子物种[PdCl]，尽管这些离子大多仍吸附在活性炭表面，且只能在溶液相中低水平检测到。这一发现为控制浸出行为以及在有机反应中稳健使用载钯炭提供了一个新的视角。
