High‐performance H 2 sensors are becoming increasingly important in detecting and monitoring H 2 . By using pyrolytic carbon as a transition layer between a Pd film and an anodic aluminum oxide substrate, a nanoporous Pd film sensor is fabricated (see figure) that has a remarkable sensing performance with the ability to detect both dilute and high concentrations of H 2 gas quickly and at room temperature.
