Sub-second and ppm-level optical sensing of hydrogen using templated control of nano-hydride geometry and composition

Detecting hydrogen is important for development of renewable energy sources. Here, the authors present lightweight optical hydrogen sensors based on a metasurface of PdCo nano-patchy particle arrays, which achieve sensitive hydrogen detection in less than 1 s, and without risk of sparking.
