Abstract:
A highly porous carbon was synthesized using a coordination complex as an unusual precursor. During controlled pyrolysis, a trinuclear copper complex, [Cuᴵᴵ₃Cl₄(H₂L)₂]·CH₃OH, undergoes phase changes with melt and expulsion of different gases to produce a unique morphology of copper-doped carbon which, upon acid treatment, produces highly porous graphitic carbon with a surface area of 857 m² g–¹ and a gravimetric hydrogen uptake of 1.1 wt % at 0.5 bar pressure at 77 K.
