Baking ‘crumbly’ carbon nitrides with improved photocatalytic properties using ammonium chloride†
Abstract
Ammonium chloride can serve as a green, unreactive and reusable template to prepare heptazine-based graphitic carbon nitrides with surface areas up to 30 m2 g−1 and up to 6 times higher photocatalytic activity, by a simplified procedure that comprises only pyrolysis of the reaction mixture containing precursor and salt.
