在中学化学演示实验中,氨催化氧化的实验是用铂作催化剂使氨氧化,其反应方程式为:4NH_3+5O_2(?)4NO(无色)+6H_2O2NO+O_2=2NO_2(红棕色)由于金属铂价格昂贵,一般学校因条件所限,对此实验无法做,教师只能是口述实验现象,学生观察不到实际的操作及现象,不能真正掌握氨催化氧化的原理。因此,要使一般学校都能做此实验,并且得到同样的实验效果,选择合适的催化剂是关键。我们在《化学
In the middle school chemistry demonstration experiment, the ammonia oxidation oxidation experiment uses platinum as a catalyst to oxidize ammonia. The reaction equation is: 4NH 3 + 5O 2 (?) 4NO (colorless) + 6H 2 O 2 NO + O 2 = 2NO 2 (reddish brown) due to metal platinum The price is expensive. In general schools, due to limited conditions, this experiment can not be done. The teacher can only dictate the phenomenon of the experiment. Students cannot observe the actual operation and phenomenon and cannot really grasp the principle of ammonia catalytic oxidation. Therefore, to enable the general school to do this experiment, and get the same experimental results, the choice of the right catalyst is the key. We are in Chemistry
