On the one hand, because of its catalytic activity, it still cannot surpass platinum, and secondly, because of its harsh synthesis conditions, it is difficult to scale up the preparation
On the one hand, because its catalytic activity still can not surpass platinum, and on the other hand, because its synthesis conditions are harsh and difficult to enlarge the preparation
On the one hand, its catalytic activity is still unable to surpass that of platinum, and on the other hand, it is difficult to enlarge its synthesis conditions<br>
