Ru on covaltent triazine frameworks (CTF) are highly active and selective catalysts for the conversion of xylitol to glycols (80% C-yield) in basic media. With increasing N-content decarbonylation reactions are suppressed leading to high glycol selectivity. The suppression can be attributed to the presence of N in the support and to metal-support interactions. The catalysts exhibit high stability and could be recycled 5 times with minor loss of activity.

在共价三嗪骨架上通过Ru从木糖醇选择性生产乙二醇–抑制脱羰反应

共价三嗪骨架（CTF）上的Ru是在碱性介质中将木糖醇转化为乙二醇（80％C收率）的高活性和选择性催化剂。随着N含量的增加，脱羰反应被抑制，导致高的乙二醇选择性。抑制作用可归因于载体中N的存在以及金属与载体的相互作用。催化剂显示出高稳定性，可以循环使用5次，而活性损失很小。
