Abstract

Ultrathin platinum nanowires obtained from wet‐synthesis with no strong binding ligands exhibit very high sensitivity toward hydrogen gas (two orders of magnitude increase compared with state‐of‐the‐art devices). Their chemical sensitivity, selectivity, and other sensing characteristics can be rationally tailored through further surface engineering. A significantly reduced cross‐sensitivity toward humidity is achieved, while the hydrogen sensitivity is preserved or even enhanced.
