20.500.12556/RUL-135235 Flow-through polyHIPE silver-based catalytic reactor Catalytic reactors performing continuously are an important step towards more efficient and controllable processes compared to the batch operation mode. For this purpose, homogenous high internal phase emulsion polymer materials with an immobilized silver catalyst were prepared and used as a continuous plug flow reactor. Porous material with epoxide groups was functionalized to bear aldehyde groups which were used to reduce silver ions using Tollens reagent. Investigation of various parameters revealed that the mass of deposited silver depends on the aldehyde concentration as well as the composition of Tollens reagent. Nanoparticles formed on the pore surface showed high crystallinity with a cuboctahedra crystal shape and highly uniform surface coverage. The example of the 4-nitrophenol catalytic reduction in a continuous process was studied and demonstrated to be dependent on the mass of deposited silver. Furthermore, productivity increased with the volumetric silver density and flow rate, and it was preserved during prolonged usage and storage. 4-nitrophenol reduction AGET ATRP heterogeneous catalysis Tollens reagent silver true false true Angleški jezik Ni določen Članek v reviji 2022-03-02 09:47:55 2022-03-02 09:47:55 2022-09-14 04:12:20 0000-00-00 00:00:00 2021 0 0 16 str. iss. 6, art. 880 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 54 2073-4360 10.3390/polym13060880 55287299 RAZ_Mravljak_Rok_2021.pdf RAZ_Mravljak_Rok_2021.pdf 1 4109658C05377AE8278791D894C4062E b26d94658e9dae12a90d4bce9505d7359b2c87b4d40d72d8622b62c846b5142c f877ac83-9a05-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154175 https://www.mdpi.com/2073-4360/13/6/880 0 c612c908-9a05-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154174 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
