摘要
文章对天然气汽车尾气净化催化剂的关键性材料--耐高温高比表面载体材料的制备及性能进行了深入的研究。结果证明,新型载体YSZ-Al2O3材料具有高比表面和耐高温性能,YSZ-Al2O3的添加对全Pd三效催化剂的耐高温性能改善明显。
The key materials-alumina for three-way catalysts in natural gas powered engines were prepared and studied. It was proved that the new alumina has good performance of high-temperature-resistant, and add it to the Pd-only three-way catalysts improve the activities and thermal stability greatly.
