Online ahead of print.ABSTRACTA rapeseed pollen biotemplate, sol-gel impregnation and calcination yielded hierarchically porous WO3. La doping formed WO3/La2WO6 heterojunctions, and Pt nanoparticles boosted interfacial catalysis. Owing to large specific surface area, heterojunction electron modulation and Pt catalytic activation, the composite delivered a high DMTS response of 520 with superior sensitivity, stability and humidity tolerance.PMID:42619571 | DOI:10.1039/d6ay01579d
