| Popis: | In this paper, we have presented the syntheses feasible scheme for reliable and suitable construction, using a two-step hydrothermal/ grinding method, g-AgI@TiO2/UiO-66-NH2 (gAT/U6N) composites. The photocatalytic efficiency was calculated by the elimination of Rhodamine B (RhB) by visible light radiation. Consequently, the optimized (AT30-U6N) exhibited a noteworthy photocatalytic performance and a rapid degradation ability for Rhodamine B with a removal efficiency of 82.9 % in 30 min, which was considerably enhanced than those of bulk U6N (22 %), bulk TiO2 (16.8 %), pure AgI (29 %) and g-AT under the identical conditions, proffering a synergistic efficacy in the hybrid materials. Remarkable amelioration in Photocatalytic efficiency was caused by the ternary structure of TiO2, U6N and photoelectrical efficiency of AgI, strongly absorbing visible light irradiation and promoting photoelectrons Transfer. This research demonstrates the superior outcome of ternary 30AT@U6N Z-scheme photocatalyst in dyed wastewater and creates a unique vision in improving U6N. |
