【摘要】 摘要:柴油车尾气排放的PM(碳黑)颗粒已引起了广泛的关注。对于柴油车尾气PM颗粒的处理必须使用高效的的催化剂来使其完全氧化。本文总结了几种不同类型的柴油车PM颗粒后处理催化剂:碱(碱土)金属催化剂、纳米贵金属催化剂、过渡金属纳米催化剂以及复合多组分催化剂,分析了它们的可能的催化机理,概述了这些催化剂的优、缺点,并对它们在实际应用中存在的问题和发展方向进行了探讨。更多还原

【Abstract】 The emission of particulate matter from diesel engines has led to widespread attention.It is necessary to apply efficient catalysts to make the particulate matter oxidated completely.A large number of candidate oxidation catalysts,their advantages and disadvantages were summarized and discussed,including alkali metal or alkali earth metal catalysts,noble metal catalysts,transitional metal catalysts and composite compound catalysts.The latest research progress of these catalysts was summarized,and some tentative suggest ions were also put forward for their practical problems and potential application prospects.更多还原
