It is known that bimetallic and trimetallic catalysts offer improved properties over single metal catalysts.

已知双金属和三金属催化剂提供了优于单金属催化剂的性能。

The catalysts can divide into two kinds: the transition metal bifunctional catalysts and oxycarbide catalysts of transition metals.

催化剂可以分为两种：过渡金属双官能催化剂和过渡金属的碳氧化物催化剂。

There seem to be two catalysts.

这里面似乎存在两项推动因素。

Catalysts make things happen.

促进者是能使事情发生。

We need catalysts to forge these new partnerships.

为了培育这些新的合作伙伴关系，我们需要催化剂。
