Loading of g‐C₃N₄ on Core‐Shell Magnetic Mesoporous Silica Nanospheres as a Solid Base Catalyst for the Green Synthesis of some Chromene Derivatives under Different Conditions

Using heterogeneous basic catalysts has a great importance in chemical reactions because of their advantages (such as easy separation and thermal stability at harsh conditions) over homogeneous catalysts. In this study, magnetic mesoporous silica nanoparticles (mSiO 2 ) containing graphitic carbon nitride layers (mSiO 2 /g‐C 3 N 4 (x)) were fabricated through a facile process (x signifies the amount of melamine applied during synthesis)....
