Can zeolites, specifically zeolite 13X, be an efficient CO2 capture agent for post-combustion technologies in the industry?
Skatter, Hedda (Bachelor thesis, 2022)Økende konsentrasjoner av klimagasser er en medvirkende årsak til global oppvarming og klimaendringer, hvor CO2 er den viktigste. For å redusere den økende mengden CO2, er karbonfangst foreslått for å redusere CO2 utslipp ... -
Copper incorporated silica aerogels: effect of synthesis parameters, characterisation and catalytic applications
Ertesvåg, Ragnhild Lea (Master thesis, 2022)Abstract will be available on 2024-07-01 -
Evaluating characterization methods for new porous functional materials
Ali, Daniel (Doctoral theses at NTNU;2021:312, Doctoral thesis, 2021)This thesis is concerned with the development and evaluation of characterization methods for new porous functional materials. Functionalized one-dimensional silicoaluminophosphates (SAPOs) were chosen as model systems for ... -
Evaluation of surfactant templates for one-pot hydrothermal synthesis of hierarchical SAPO-5
Ali, Daniel; Zeiger, Caren; Azim, Muhammad Mohsin; Lein, Hilde Lea; Mathisen, Karina (Peer reviewed; Journal article, 2020)Hierarchical SAPO-5 molecular sieves were synthesized with three different mesopore structure-directing agents (meso-SDAs) (cetyltrimethylammonium bromide (CTAB), myristyltrimethylammonium bromide (MTMAB) and [3-(trime ... -
Hierarchical SAPO-34 Catalysts as Host for Cu Active Sites
Fernandes Pape Brito, Julio C.; Miletto, Ivana; Marchese, Leonardo; Ali, Daniel; Azim, Muhammad Mohsin; Mathisen, Karina; Gianotti, Enrica (Peer reviewed; Journal article, 2023)Cu-containing hierarchical SAPO-34 catalysts were synthesized by the bottom-up method using different mesoporogen templates: CTAB encapsulated within ordered mesoporous silica nanoparticles (MSNs) and sucrose. A high ... -
Ionothermal Synthesis of Conventional and Hierarchical SAPO-11 and Framework Incorporation of Iron
de Alwis, Kudachchige Asanga Geethanjana (Master thesis, 2021)This project focuses on the ionothermal synthesis and characterization of conventional and hierarchical SAPO-11 and the incorporation of iron into the SAPO-11 framework. Conventional SAPO-11 was synthesized by following ... -
Is sustainable production of the MOFs MIL-101 and MOF-5 possible without reducing the hydrogen storage capacity of the material?
Tøgersen, Frida (Bachelor thesis, 2022)Metal organic frameworks (MOFs) er noen av de mest lovende porøse materialene når det kommer til hydrogenlagring, hvorav to av de mest lovende er MIL-101 og MOF-5. De konvensjonelle syntesene av de to MOFene involverer ... -
Nickel incorporated silica aerogels for the catalytic hydration of carbon dioxide.
Heistad, Gjermund (Master thesis, 2023)Denne oppgaven investigerer potensialet for å inkorporere nikkel i en silika aerogel atomisk og om en slik katalysator vil være aktiv for hydrering av karbondioksid. For å oppnå dette ble det brukt en optimalisert medforløper ... -
Pinpointing basic sites formed upon incorporation of iron in hierarchical SAPO-11 using catalytic model reactions
Ali, Daniel; Li, Zhihui; Azim, Muhammad Mohsin; Lein, Hilde Lea; Mathisen, Karina (Peer reviewed; Journal article, 2022)By utilizing previously established catalytic model reactions, a method for probing the topological location of transition metal sites incorporated in hierarchical silicoaluminophosphates (SAPOs) is presented. For the first ... -
Pore Characteristics and Acid Properties of Hierarchical SAPO-34
Ali, Daniel (Master thesis, 2015)This thesis investigates the pore connectivity and acid properties of the hierarchical SAPO 34 molecular sieve. The hierarchical version of the SAPO 34 molecular sieve was synthesized using the dry gel conversion as ... -
Potensielle adsorpsjonsteknikker for fangst og seperasjon av CO2 ved MOF
Kjenes, Mats (Bachelor thesis, 2022)Dagens samfunn er for tiden dominert av gass- og kullkraftverk, og vil være det i den overskuelige fremtiden. I nyere tid har det dermed blitt rettet en del forskning mot materialer som kan fange og separere CO2 fra ... -
