Mesoporous graphitic carbon nitride (MGCN) materials and method of making said MGCN materials is described. The MGCN materials include a three dimensional cyanamide based carbon nitride matrix having tunable pore diameters, a pore volume between 0.40 and 0.80 cm.sup.3 g.sup.1, and a surface area of 195 to 300 m.sup.2 gm.sup.1. The matrix comprises sheets of three dimensionally arranged s-heptazine (tri-s-triazine) units. The MGCN materials are used as catalysts in aldol condensation reactions, in particular Knoevenagel reactions. The mesoporous structure is obtained by means of a silica template like KIT-6, which is removed after polymerisation of the cyanamide monomers.
