摘要: 通过水热法合成具有协同机制的三元复合材料Bi2Fe4O9/g-C3N4/UiO-66,研究表明三元复合光催化剂的催化活性要高于二元材料和纯材料。这主要是由于Bi2Fe4O9更易于和g-C3N4结合形成稳定的Z-scheme异质结结构,使三元复合材料增强了可见光响应能力,提高了电子-空穴分离能力,增强了空穴和电子的氧化还原能力。 |

Abstract: Bi2Fe4O9/g-C3N4/UiO-66 ternary composites synthesized by a facile hydrothermal method possess synergistically enhanced visible-light photocatalytic performance for degradation of both RhodamineB dye and colorless phenol solutions as compared with purity materials of g-C3N4, Bi2Fe4O9 and UiO-66. The ternary composite materials show increased visible light absorption, efficient separation of charge carriers, strong redox capability via Z-scheme Bi2Fe4O9/g-C3N4 heterojunction and high adsorption ability. |
