提出了一种使用金属离子交换树脂的选择性低温碳热还原（CTR）工艺。通过该方法制备的钨化合物由直径约10-20 nm的超细颗粒组成，这些颗粒高度分散在多孔碳基体中。新的 CTR 工艺适用于任何其他金属元素，具体取决于树脂类型、金属离子种类和热处理条件的组合。
A selective, low-temperature carbothermal reduction (CTR) process with metal ion-exchanged resin has been proposed. The tungsten compounds prepared by this method consisted of ultrafine particles of around 10–20 nm in diameter which were dispersed highly in the porous carbon matrix. The new CTR process is applicable for any other metal elements, depending on the combination of resin type, metal ionic species and heat treatment conditions.
