文摘

Efforts are taken to deposit WO3 directly on to glass substrate without assistance of seed layer hydrothermal technique. 2D nanoplates like structure of WO3 were synthesized via simple route. The 2D nanoplates of WO3 exhibited excellent and highly selective gas response ∼10 for 5 ppm. The new synthesis route and sensing behavior of as synthesized WO3 nanoplates revealed a promising candidate for fabricating low-consumption gas sensors.
