We have carbonized COP-M with or without using template KOH
and compared their adsorption properties under ambient condi-tions. Thus,a 4:1 mixture of KOH and COP-M was thermally an-nealed at 600–700 °C under N2 atmosphere, which produces KCOP-M-x (x is the activation temperature).Similarly,COP-M-x was produced from direct pyrolysis of COP-M at 600–700 °C under N2, without using any KOH (Scheme 1).
