因为氮原子有优异的给电子特性，从而协同活性中心实现甲醛分子的催化氧化。

Because nitrogen atoms have excellent electron donating properties, the catalytic oxidation of formaldehyde molecules can be achieved by cooperating with the active centers. Nitrogen vacancies are formed when nitrogen atoms evaporate, and they are able to trap oxygen molecules, thereby enhancing the ability of formaldehyde to catalyze oxidation.

Because nitrogen atoms have excellent electron donor properties, they cooperate with active centers to realize the catalytic oxidation of formaldehyde molecules. Nitrogen atoms will form nitrogen vacancies after evaporation, which can capture oxygen molecules and improve the catalytic oxidation of formaldehyde.
