Porous polymer catalysts with hierarchical structures.
The emergence of porous organic polymers (POPs) has provided great opportunities for new applications in heterogeneous catalysis owing to their unprecedented intrinsic structural features such as high surface areas, extraordinary framework stabilities and chemically adjustable compositions. In this tutorial review, representative recent developments in the POPs-based catalysts with hierarchical...
متن کاملConcurrent design of hierarchical materials and structures
Significant achievements have been demonstrated in computational materials design and its broadening application in concurrent engineering. Best practices are assessed and opportunities for improvement identified, with implications for modeling and simulation in science and engineering. Successful examples of integration in undergraduate education await broader dissemination.
متن کاملOrganosilane with gemini-type structure as the mesoporogen for synthesis of hierarchical porous ZSM-5 zeolite
A new kind of organosilane (1,6-bis (diethyl(3-trimethoxysilylpropyl)ammonium) hexane bromide) with a geminitype structure was prepared and used as a mesoporogen for the synthesis of hierarchical porous ZSM-5 zeolite. There are two quaternary ammonium centers along with double hydrolysable -RSi(OMe)3 fragments in the organosilane, which results in a strong interaction between this mesoporogen a...
متن کاملHierarchical porous materials made by drying complex suspensions.
Porous structures containing pores at different length scales are often encountered in nature and are important in many applications. While several processing routes have been demonstrated to create such hierarchical porous materials, most methods either require chemical gelation reactions or do not allow for the desired control of pore sizes over multiple length scales. We describe a versatile...
متن کاملMesoporous materials with zeolite framework: remarkable effect of the hierarchical structure for retardation of catalyst deactivation.
Hierarchical MFI zeolite was synthesized following a synthesis route using organic-inorganic hybrid surfactants; the resultant zeolite with mesoporous/microporous hierarchical structure exhibited remarkably high resistance to deactivation in catalytic activity of various reactions such as isomerization of 1,2,4-trimethylbenzene, cumene cracking, and esterification of benzyl alcohol with hexanoi...
