To address this, we develop a simple and controllable two\u2010step strategy. A Sn\/Pd bimetallic precursor is first prepared via mild hydrothermal deposition, then calcined in inert argon to realize in situ phase transformation and interfacial regulation, successfully yielding an SnO\n                    <jats:sub>2<\/jats:sub>\n                    \u2010PdO\u2010Pd\n                    <jats:sub>2<\/jats:sub>\n                    Sn (SPO\/PS) composite suitable for rapid and efficient low\u2010temperature hydrogen detection.
