钯膜对氢的扩散具有显著的亲和力，因此对膜反应器中氢的分离和纯化具有重要意义。然而，钯是昂贵的，它的薄膜在几个氢分离循环后就会变脆。用银合金化已被证明可以克服钯的脆化问题。钯银薄膜已通过几种方法生产，但都有缺点，如难以控制合金成分。本研究探索了两种很有前途的喷墨打印方法：喷墨和气溶胶喷墨。这两种方法都具有潜在的优点，例如直接图像化，减少浪费，使薄膜生产成为可能，并允许控制合金成分。首次使用钯银金属有机分解（MOD）油墨通过喷墨打印生产钯银合金，该油墨在300°C的温度下与氮气结合。同样，这项研究也展示了一种开创性的气溶胶喷射打印方法，显示了一种新的室温方法的潜力，用于钯银MOD油墨的沉积。这种低温方法被认为是一项重要的发展，因为钯银MOD油墨最初设计用于在加热的衬底上沉积。
Palladium films hold signicance due to their remarkable affinity for hydrogen diffusion, rendering them valauble for the seperation and purification of hydrogen in membrane reactors. However, palladium is expensive, and its films can become brittle after only a few cycles of hydrogen separation. Alloying with silver has been shown to overcome the problem of palladium embrittlement. Palladium‐silver films have been produced via several methods but all have drawbacks, such as difficulties controlling the alloy composition. This study explores two promising jet printing methods: Inkjet and Aerosoljet. Both methods offer potential advantages such as direct patterning, which reduces waste, enables thin film production, and allows for the control of alloy composition. For the first time, palladium‐silver alloys have been produced via inkjet printing using a palladium‐silver metal organic decomposition (MOD) ink, which alloys at a temperature of 300 °C with nitrogen. Similarly, this study also demonstrates a pioneering approach for Aerosol Jet printing, showing the potential of a novel room‐temperature method, for the deposition of palladium‐silver MOD inks. This low temperature approach is considered an important development as palladium‐silver MOD inks are originally designed for deposition on heated substrates.
