相反，过渡金属硫化物作为催化剂反应活性低、不容易中毒显示了很高的选择性。
In contrast, transition-metal sulfides are less reactive and susceptible to poisoning and can show higher selectivity.
过渡族金属硫化物是一类很好的热电池正极材料。
The transition-metal sulphides are widely used as cathode in thermal batteries, especially iron disulphide and cobalt disulphide.
