A high-performance hydrogen gas sensor using ultrathin polypyrrole-coated CNT nanohybrids

摘要

A novel strategy for designing ultrathin polypyrrole skin-coated carbon nanotube (CNT) nanohybrids is demonstrated by vapor deposition polymerization (VDP). The ultrathin skin technology provides a stable immobilization of the mono-disperse Pd nano-particles (NPs) on the CP-CNT nanohybrid surface, leading to a high-performance hydrogen gas sensor at room temperature.
