Simple pyrolysis of urea into graphitic carbon nitride with recyclable adsorption and photocatalytic activity

, 2011
Graphitic carbon nitride (g-C3N4) was produced on a large scale by the pyrolysis of urea under ambient pressure without additive assistance. The retainable pyrolysis-generated self-supporting atmosphere and the reaction temperature are two necessary ...
