    Abstract: A method of lowering undesirable vehicle exhaust emissions includes preparing a catalyst for use in the exhaust stream of the vehicle. The method includes preparing a solution of an ammonia metal complex, applying the complex to an alumina substrate, heating the substrate to remove water and ammonia, and converting the metal to its active form. Additional metals may be complexed in a similar manner and deposited on separate substrates and the separate substrates may then be mixed to achieve any desired proportion of the metal catalysts.

    Abstract translation: 减少不期望的车辆废气排放的方法包括制备用于车辆排气流中的催化剂。 该方法包括制备氨金属络合物的溶液,将配合物施加到氧化铝基底上,加热基底以除去水和氨,并将金属转化为活性形式。 另外的金属可以以类似的方式复合并沉积在单独的基底上,然后可以将分开的基底混合以实现任何所需比例的金属催化剂。
