摘要: Polymeric carbon nitride (PCN) is usually synthesized from nitrogen-rich monomers such as cyanamide, melamine, and urea, but rather disordered in many cases. Now, a new allotrope of with internal heterostructures was obtained by co-condensation very electron poor (for example, 5-amino-tetrazole nucleobases) the presence mild molten salts NaCl/KCl) to mediate polymerization kinetics thus modulate local structure, charge carrier properties, most importantly HOMO LUMO levels. Results reveal that as-prepared NaK-PHI-A material shows excellent photo-redox activities because nanometric hetero-structure which enhances visible light absorption promotes separation different domains.
