Abstract:Ultrasensitive
photoelectric detection of nitrogen dioxide (NO2) with
PHI under visible light irradiation at room temperature
(RT) remains an ongoing challenge due to the low charge separation
and scarce adsorption sites. In this work, a dimensionally matched
ultrathin CoNiHHTP MOF/PHI Z-scheme heterojunction is successfully
constructed by taking advantage of the π–π interactions
existing between the CoNiHHTP MOF and PHI. The amount-optimized heterojunction
possesses a record detection limit of 1 ppb (response… Show more
