Facile sol–gel auto-combustion synthesis of β-Zn3B2O6 nanoparticles: optical and photocatalytic studies

The present work reports a simple sol–gel auto combustion route for synthesizing β-Zn 3 B 2 O 6 nanoparticles using Zn(NO 3 ) 2 ·6H 2 O and H 3 BO 3 precursors. Effect of acid type, gelling agent, and acid-to-gelling agent ratio on morphology of prepared products was well studied. Moreover, the effi...

Zusammenfassung:	The present work reports a simple sol–gel auto combustion route for synthesizing β-Zn 3 B 2 O 6 nanoparticles using Zn(NO 3 ) 2 ·6H 2 O and H 3 BO 3 precursors. Effect of acid type, gelling agent, and acid-to-gelling agent ratio on morphology of prepared products was well studied. Moreover, the efficiency of β-Zn 3 B 2 O 6 nanoparticles as a photocatalyst for the decolorization of an azo dye (Acid Red 88; AR88) using ultraviolet irradiation was evaluated and >81% of AR88 was decolorized under UV light after 90 min. Also, the effect of particle size and morphology on the photocatalytic activity was evaluated.
