“…Several analytical methods have been developed to evaluate that relevant water quality parameter [12][13][14][15][16][17] . The major barrier for accurate quantification of BTEX are their low concentrations (Aqueous miscibility: benzene, 1790 mg.L -1 , toluene, 526 mg.L -1 , ethylbenzene, 169 mg.L -1 , o-xylene, 178 mg.L -1 , m-xylene, 161 mg.L -1 , p-xylene, 162 mg.L -1 ) 4,5 and the several interferents present in the water bodies.…”

“…However, BTEX are neurotoxic and easily volatilized; even low concentrations of BTEX will cause neurasthenia, headache, and other symptoms. , Therefore, real-time and accurate detection of BTEX in a real environment is of great importance. In recent years, various detection techniques such as gas chromatography–mass spectrometry (GC-MS), , high-performance liquid chromatography (HPLC), , and fluorescent probes have been used to detect BTEX. However, these detection methods depend on bulky and costly instruments, which greatly hinder their applications in a specific environment.…”

A Pt nanoparticle-immobilized WO 3 material is a promising candidate for catalytic reactions, and the surface and electronic structure can strongly affect the performance. However, the effect of the intrinsic oxygen vacancy of WO 3 on the d-band structure of Pt and the synergistic effect of Pt and the WO 3 matrix on reaction performance are still ambiguous, which greatly hinders the design of advanced materials. Herein, Pt-decorated WO 3 nanosheets with different electronic metal−support interactions are successfully prepared by finely tuning the oxygen vacancy structure of WO 3 nanosheets. Notably, Pt-modified WO 3 nanosheets annealed at 400 °C exhibit excellent benzene series (BTEX) sensing performance (S = 377.33, 365.21, 348.45, and 319.23 for 50 ppm ethylbenzene, benzene, toluene, and xylene, respectively, at 140 °C), fast response and recovery dynamics (10/7 s), excellent reliability (σ = 0.14), and sensing stability (φ = 0.08%). Detailed structural characterization and DFT results reveal that interfacial Pt δ+ -O v -W 5+ sites are recognized as the active sites, and the oxygen vacancies of the WO 3 matrix can significantly affect the d-band structure of Pt nanoparticles. Notably, Pt/WO 3 -400 with improved surface oxygen mobility and medium electronic metal−support interaction facilitates the activation and desorption of BTEX, which contributes to the highly efficient BTEX sensing performance. Our work provides a new insight for the design of high-performance surface reaction materials for advanced applications.
