本文提出铜-铬型炭催化剂的活性物质为碱式铬酸铜-水配位络合物,其结构可写为■从热差分析和吸水等温线的数据支持这种活性物质的可能组成结构。催化剂上括性物质的分布大部份位于活性炭的大孔部位,在靠近中一微孔表面仍有小部份活性物质,因此当空气的潮湿度高于90%以上时,催化剂孔内吸附大量水,使中-微孔表面上沉积的活性物质被水覆盖而活性下降。 This paper suggests that the active species of the copper-chromium type carbon catalyst is a basic copper chromate-water coordination complex with a structure that can be written as ■ The possible compositional structure of this active species is supported by data from the thermal differential analysis and the water absorption isotherms . Most of the distribution of the catalyst on the macroporous activated carbon surface, there is still a small part of the active substance close to the surface of a micro-pore, so when the air humidity is higher than 90%, the catalyst pore adsorption large Water causes the active substance deposited on the mesoporous surface to be covered with water and its activity decreases.
