Microwave-Assisted Synthesis of Porous ZnO/SnS₂ Heterojunction and Its Enhanced Photoactivity for Water Purification

Table 2

Pollutants and some experimental conditions used in testing the photocatalytic activity of the porous ZnO/SnS₂ heterostructures. Unless otherwise indicated, reactions were performed at (30 ± 1)°C in a water-jacketed photoreactor, continuously air/argon-sparged and stirred at 400 rpm.
