Fabrication of the TiO2/Ti3C2 loaded ceramic membrane targeting for photocatalytic degradation of PPCPs: ciprofloxacin, tetracycline, and ibuprofen
Photocatalytic membranes offer an effective strategy to overcome the difficulties of solid-liquid separation and secondary contamination of powdered photocatalysts. MXene is a 2D material of layered Ti3C2, which is considered to limit electron-hole separation and contribute to photocatalysis. In this work, the etched Ti3C2 MXene was loaded on the surface of ceramic membranes using polydopamine (PDA) as a binder, followed by one-step calcination to produce TiO2 nanoparticles (NPs) in situ. The characterizations supported that the TiO2/Ti3C2 ceramic membranes had high mechanical strength while retaining the layered structure of Ti3C2, which was conducive to the inhibition of electron and hole complexation, improving the photocatalytic performance. Degradation experiments revealed that the material showed enhanced degradation of pharmaceuticals and personal care products (PPCPs) such as ciprofloxacin (CIP), tetracycline (TCN) and ibuprofen (IBP). The LC-MS and toxicity prediction models indicated that the developmental toxicity of CIP degradation products decreased with prolonged photocatalytic reaction, exhibiting no acute toxicity to fish. The MT650 exhibited significantly enhanced water flux properties (320 L/(m2·h)). The TiO2/Ti3C2 ceramic membranes explored in this work are expected to target the treatment of PPCPs with excellent engineering promise.
期刊介绍:
Frontiers of Environmental Science & Engineering (FESE) is an international journal for researchers interested in a wide range of environmental disciplines. The journal''s aim is to advance and disseminate knowledge in all main branches of environmental science & engineering. The journal emphasizes papers in developing fields, as well as papers showing the interaction between environmental disciplines and other disciplines.
FESE is a bi-monthly journal. Its peer-reviewed contents consist of a broad blend of reviews, research papers, policy analyses, short communications, and opinions. Nonscheduled “special issue” and "hot topic", including a review article followed by a couple of related research articles, are organized to publish novel contributions and breaking results on all aspects of environmental field.
