Palladium nanoparticle-decorated multi-layer Ti 3 C 2 T x dual-functioning as a highly sensitive hydrogen gas sensor and hydrogen storage

nanocomposite showed superb hydrogen-sensing capability even at room temperature with sharp, large, reproducible, concentration-dependent, and hydrogen-selective responses. Furthermore, the nanocomposite also unveiled some extent of hydrogen storage capability at room temperature and 77 K, raising a possibility that it can dual-function as a hydrogen sensor and hydrogen storage.
