通过溅射PTFE薄膜增强了Pd合金薄膜的催化性能，从而大大改善了Pd基和Pd催化的氢传感器和储氢材料中的氢吸附和脱附。显着增强的催化性能是由于化学改性的催化剂表面的溅射PTFE导致可能的变化，在氢吸附过程中所涉及的中间物种的结合强度。
The catalytic properties of Pd alloy thin films are enhanced by a thin sputtered PTFE coating, resulting in profound improvements in hydrogen adsorption and desorption in Pd-based and Pd-catalyzed hydrogen sensors and hydrogen storage materials. The remarkably enhanced catalytic performance is attributed to chemical modifications of the catalyst surface by the sputtered PTFE leading to a possible change in the binding strength of the intermediate species involved in the hydrogen sorption process.
