Rapid screening of gaseous catalysts in methane activation using ICP-QQQ-MS†
A novel platform for rapid screening of gaseous catalysts in methane activation using ICP-QQQ-MS was developed. The gaseous ion catalysts could be produced in an ICP torch from the bulk solution. The dynamic reaction cell in the ICP-QQQ-MS could be used as the reactor to mix methane with the gaseous ion catalyst to examine the important parts of the catalytic reaction. In this work, 37 kinds of gaseous catalysts were rapidly screened and the results obtained by using the ICP-QQQ-MS were also validated by using another dielectric barrier discharge reactor. The ICP-QQQ-MS platform was not only suitable for catalyst screening in methane activation, but also suitable for other full reactions.
