One-pot sonochemical synthesis of 3D flower-like hierarchical AgCl microsphere with enhanced photocatalytic activity.

A highly uniform 3D flower-like hierarchical AgCl microsphere was prepared by sonochemical method with the existence of β-dextrin. The 3D flower-like hierarchical structure can be ascribed to the existence of β-dextrin, which provides nucleation sites for the growth of nanosheets because of the strong interaction between β-dextrin and Ag. The 3D flower-like hierarchical AgCl microspheres were assembled by numerous interleaving nanosheet petals with small thickness.

Facile photo-ultrasonic assisted reduction for preparation of rGO/AgCO nanocomposites with enhanced photocatalytic oxidation activity for tetracycline.

Various antibiotics in the aquatic systems have threat the aquatic ecosystem balance and the human health. In this study, a degradation treatment method for tetracycline (TC), one of the commonly used antibiotics, was explored by using novel photocatalysts of rGO/AgCO under simulated sunlight, because conventional treatment methods are not efficient on the removal of TC. rGO/AgCO nanocomposites were synthesized via a facile photo-ultrasonic assisted reduction method.

Facile One-Step Sonochemical Synthesis and Photocatalytic Properties of Graphene/AgPO Quantum Dots Composites.

In this study, a novel graphene/AgPO quantum dot (rGO/AgPO QD) composite was successfully synthesized via a facile one-step photo-ultrasonic-assisted reduction method for the first time. The composites were analyzed by various techniques. According to the obtained results, AgPO QDs with a size of 1-4 nm were uniformly dispersed on rGO nanosheets to form rGO/AgPO QD composites.
