■ Title: Making Porous Materials Respond to Light for Adsorptive Separation

ABSTRACT

Adsorptive separation is a widely applied in chemical industry for purification of raw materials and products. However, traditional adsorbents have inflexible properties and suffer from the trade-off between selective adsorption and efficient desorption. In recent years, our group have developed a series of photoresponsive adsorbents, which might provide new avenues for adsorptive separation. These photoresponsive adsorbents possess active sites which can be regulated through steric hindrance or tunable adsorbent-adsorbate interactions. Therefore, variation in adsorptive capacity is achieved through photomodulation, which is different from conventional temperature- and pressure-swing adsorption processes and the corresponding adsorption/desorption cycles are energy-saving.

SPEAKER

Lin-Bing Sun received his PhD from Nanjing University in 2008. After that, he joined the faculty of Nanjing Tech University and State Key Laboratory of Materials-Oriented Chemical Engineering. He was a postdoctoral research associate at Texas A&M University in 2011-2012. Professor Sun’s current research interests focus on fabrication of porous functional materials (ranged from mesoporous molecular sieves to metal-organic frameworks and porous organic polymers) as well as their applications in adsorption and catalysis. He is the principal investigator of various projects such as the National Science Fund for Distinguished Young Scholars. His work has led to more than 200 papers in peer-reviewed journals including Chem. Rev., Chem. Soc. Rev., Acc. Chem. Res., Nature Commun., J. Am. Chem. Soc., Angew. Chem. Int. Ed., and AIChE J. as well as around 20 patents. He also coauthored two books including Dictionary of Chemical Technology.
