Abstract

Benzene series as highly toxic gases have inevitably entered human life and produce great threat to hu-man health and ecological environment,and thus it is distinctly meaningful to monitor benzene series with quickly,real-time and efficient technique.Herein,novel sulfur-doped mesoporous WO3 materials were synthesized via classical in-situ solvent evaporation induced co-assembly strategy combined with doping engineering,which possessed highly crystallized frameworks,high specific surface area(40.9-63.8 m2/g)and uniform pore size(∼18nm).Benefitting from abundant oxygen vacancy and defects via S-doping,the tailored mesoporous S/mWO3 exhibited excellent benzene sensing performance,including high sensitivity(50 ppm vs.48),low detection limit(ca.500 ppb),outstanding selectivity and favorable stability.In addition,the reduction of band gap resulted from S-doping promotes the carrier migration in the sensing materials and the reaction at the gas-solid sensing interfaces.It provides brand-new ap-proach to design sensitive materials with multiple reaction sites.
