摘要：In this study, we designed SiNX solid-state nanopores to detect the temperature effect on the hydrogen nanobubble formation. Here, we integrated a temperature controller with the highly sensitive nanopore. As the temperature decreases from 25 degrees C to 5 degrees C, the occurrence of the nanobubble nucleation inside a 12.3 nm SiNX nanopore confined space decreased from 102 s(-1) to 23 s(-1), and the life-time of nanobubbles increased from 1.16 ms to 4.78 ms. The results further gave the activation energy for nanobubble nucleation which was 8.1 x 10(-20) J with a 12.3 nm SiNX nanopore. Our method provides an efficient analytical tool for revealing the temperature-dependent nanobubble nucleation, which further benefits the fundamental understanding of nanobubble nucleation.
