光催化水净化是一种有效的环境保护方法，可用于去除工业废水中的有毒有害物质。然而，目前使用的基于tio2的催化剂只吸收太阳光谱中紫外线区的一小部分，导致效率较低。在本文中，我们展示了一种二硫化钼/沸石咪唑酸框架-8 （MoS2/ZIF-8）复合光催化剂，其光催化降解环丙沙星（CIP）和盐酸四环素（TC）分别提高了1.21和1.07倍。初步确定了CIP和TC在催化过程中的转化产物，其中金属有机骨架（MOF）被认为是主要活性物质，孔被认为是主要活性物质。MoS2/ZIF-8纳米复合材料的产氢率是MoS2的1.79倍。本研究通过优化表面纳米异质结结构的构建，为探索新颖高效的1T/2H-MoS2/ mof基光催化剂提供了新的视角。经稳定性测试，复合光催化剂经久耐用，催化性能保持不变。因此，基于1T/2H-MoS2/ mof的光催化剂在抗生素降解工程中具有良好的应用前景。(c) 2019年提交人。由爱思唯尔有限公司代中国工程院高等教育出版社有限公司出版。
Photocatalytic water purification is an efficient environmental protection method that can be used to eliminate toxic and harmful substances from industrial effluents. However, the TiO2-based catalysts currently in use absorb only a small portion of the solar spectrum in the ultraviolet (UV) region, resulting in lower efficiency. In this paper, we demonstrate a molybdenum disulfide/zeolitic imidazolate framework-8 (MoS2/ZIF-8) composite photocatalyst that increases the photocatalytic degradation of ciprofloxacin (CIP) and tetracycline hydrochloride (TC) by factors of 1.21 and 1.07, respectively. The transformation products of CIP and TC from the catalysis processes are tentatively identified, with the metal-organic framework (MOF) being considered to be the main active species with holes being considered as the main active species. The hydrogen production rate of the MoS2/ZIF-8 nanocomposites is 1.79 times higher than that of MoS2. This work provides a novel perspective for exploring original and efficient 1T/2H-MoS2/MOF-based photocatalysts by optimizing the construction of surface nano-heterojunction structures. The composite photocatalyst is found to be durable, with its catalytic performance being preserved under stability testing. Thus, 1T/2H-MoS2/MOF-based photocatalysts have excellent prospects for practical antibiotic-degradation engineering. (C) 2019 THE AUTHORS.
