We utilized untreated and mildly oxidized CNTs for monolith For the stability of the synthesized monoliths, we determined the comparable synthesis. Both supplies enable the formation of steady monoliths using a dispersion and gelation ofsurface location. Nonetheless, by using oxidized CNTs the conductivity on the monoliths factor. distinct the particles by ultrasonication throughout the synthesis method to be a keyThus, ultrasonic treatment led tow robust gelation as drying within a heating chamber additional stabilized the CNT network. We utilized untreated and mildly oxidized CNTs for monolith synthesis. Both materials enable the formation of stable monoliths with a comparable precise surface location. Having said that, by using oxidized CNTs the conductivity of the monolithsAppl. Sci. 2021, 11,12 ofcould be strongly improved, indicating a more homogenous and pronounced particle network. Upon electrochemical characterization, the presence of capacitive and faradaic currents could be determined for both materials. Nonetheless, pronounced faradaic currents were detected with oxidized monoliths, top to an overall stronger current response. The potential-controlled adsorption of maleic acid was investigated as a proof of concept for an electrosorption method on CNT monoliths. Untreated and oxidized monoliths showed electrosorption behavior. Whilst the adsorption capacity could be improved by means of oxidation, strong heterogeneous interactions still complicate a potential-triggered release of your model analyte. Within this respect, the utilization of electro-active composites may be a attainable solution to control the reversible electrosorption onto CNT monoliths. Additionally, the interfacial interactions guiding the reversible electrosorption of organic molecules should be additional examined. Together with the aim of developing a potential-controlled process for biotechnological separations, we continue working on a preparative setup for the targeted electrosorption onto CNT monolith electrodes.Supplementary Supplies: The following are obtainable on the net at https://www.mdpi.com/article/10 .3390/app11209390/s1, Figure S1: Test rig for conductivity measurements on cylindrical monoliths.
