文摘

Synthesis of NiO assembled TiO2 composites using ultrasound assisted wet impregnation method Coupling of wide band-gap NiO with TiO2 enhances the absorption to visible region A synergistic of 4.8 fold is achieved when ultrasound is combined with photocatalysis under diffused sunlight The reduction of TOC confirms the mineralization of MO dye TiO2–NiO composite shows higher photocurrent response than bare TiO2
