铵离子是由一个氮原子和四个氢原子组成的,其中一个氢原子与氮原子形成离子键,其余三个氢原子与氮原子形成共价键。氮原子有5个外层电子,但作为铵离子,它失去了一个电子,所以只有4个外层电子参与成键。每个氢原子有1个外层电子。在铵离子中,氮原子的4个外层电子与4个氢原子的4个外层电子形成4个共价键。 铵...

Acetone, ethanol and methanol gas molecules were successfully detected by using 3D Ti3C2Tx MXene as a sensor [160]. The developed sensor exhibited lower detection limits (ppb level) due to their morphology and porous structure. Ti3C2 MXene was efficiently used as a sensor for the detection ...
