Graphitic carbon nitride is an organic semiconductor material composed of carbon and nitrogen. Theoretical calculations have shown that when g-CN is grown into tube shapes, the affinity for hydrogen adsorption on nitrogen atoms improves compared to sheet forms, suggesting its potential application as a hydrogen storage material. We have synthesized g-CN nanotubes (hereinafter, g-CNT) and reported that their application to hydrogen gas sensors results in improved sensor sensitivity compared to sheet forms. However, the previously reported g-CNT contained structures other than the tubular form, and the characteristics of the tubes were not sufficiently evaluated. Therefore, in this study, we attempted to separate and purify the synthesized g-CNT to extract the tubular structures. The extracted samples were then applied to quartz crystal microbalance (QCM)-type hydrogen gas sensors to investigate the effect of the tubular structures on sensor performance.
