One-step synthesis of in-situ N-doped ordered mesoporous titania for enhanced gas sensing performance

A simple in situ N-doping method was developed to synthesize the ordered mesoporous TiO2. The obtained material has excellent gas sensing performance, especially extremely fast response-recovery dynamics (response/recovery time was 4s/4s) and enhanced sensitivity (which is 11.6 times of undoped counterpart) for acetone.277
