摘要
考察过渡金属氧化物催化剂深度氧化活性以及吡啶氧化过程NO_x控制能力。结果表明,各类有机物氧化的难易程度与它们的极性大小有一定的对应关系,极性越大,包容易氧化。对于吡啶,催化剂的氧化活性与氧化过程NO_x控制能力成正比。随着过渡金属氧化物生成焓(-ΔAH_0)增加,催化剂对丙酮的氧化活性下降,而对吡啶、苯的氧化活性呈现最低点。
The catalytic activity of transition metal oxide catalysts for acetone,pyridine andbenzene,and NOx control ability for pyridine oxidation were studied.The oxidation activityof some organic substances on oxide catalysts coincides with their polarity.The easier theoxidation of organic substances,he larger will be the polarity.As the heat of formation ofthe metal oxides rises,the oxidatioh activity shows a minimum。The oxidation activity of theoxide catalysts is in direct proportion to the NOx control ability for pyridine oxidation.
