Abstract：
Metal-organic frameworks (MOFs), constructed by joining metal-containing units with organic linkers, have received tremendous attention due to their variety of potential applications. However, most of these MOFs still suffer from the insufficient hydrothermal stability, which precludes them to be applied in processes involving water. In this presentation, continuous water stable zirconium (IV) based MOF(UiO-66) membranes have been prepared. The membrane exhibited excellent multivalent ion rejection based on size exclusion with good permeability and high stability, suggesting the developed UiO-66 membrane as a promising candidate for water desalination. Furthermore, highly effective removal of heavy metal (arsenic) from water is realized by using UiO-66 as adsorbent. A reactive adsorption mechanism is proposed based on the raised Zr-O-As bonds. With the superior adsorption performance towards aquatic arsenic species, UiO-66 could work as a promising advanced adsorbent in the arsenic decontamination industry for water treatment.
Introduction：
Dr. Xinlei Liu received his BS degree (2007) in Chemistry from Northwest University (Xi’an, China) and PhD degree (2013) in Physical Chemistry from Dalian Institute of Chemical Physics, Chinese Academy of Sciences under the supervision of Prof. Weishen Yang and Prof. Yanshuo Li. From 2013, he moved to Prof. Kang Li’s group as a postdoctoral research fellow in Imperial College London. More than ten papers have been published by him in Science, AngewChem etc., coupled with two PCT patents. He won the Rector's Award of Chinese Academy of Sciences and First Class Award of Yanchang Petroleum Company. His recent research interests focus on the studies of porous materials (e.g. Zeolites, MOFs), polymers and membranes for the applications of biofuel production, H2 purification, CO2 capture and water treatment etc.
