Abstract
A method for synthesizing a Cu2(OH)3NO3/CaSiO3@g-C3N4 nanostructure includes mixing a calcium silicate (CaSiO3), a graphite-phase carbon nitride (g-C3N4) and a copper salt in a glycol solvent to form a mixture. The method also includes microwaving the mixture to form the nanostructure having a multi-phase crystalline structure with controlled morphology.
