(2023) Influence of Potassium-Based Activation on Adsorptive Properties of Carbon Spheres Modified with Iron(III) Citrate. Materials, Vol. 16, iss. 15, pp. 1-18, no. art. 5227. https://doi.org/10.3390/ma16155227https://hdl.handle.net/20.500.12539/2001Composites synthesized from iron(III) citrate and carbon spheres, and activated with potassium compounds were prepared and then characterized using XRD, SEM, and low-temperature nitrogen adsorption methods. The adsorption properties of the composites toward carbon dioxide were assessed using CO2 uptake measurement, as well as by measuring their selectivity toward carbon dioxide, given their further application as photocatalysts for the reduction of this gas. The effect of changing preparation conditions on the structural and adsorption properties of the material was assessed. The potential strength of such material is a synergistic effect between the high adsorption capacity related to the microporosity of carbon spheres combined with the catalytic properties of iron particles.enAttribution-NonCommercial-NoDerivs 3.0 Polandcarbon spheresiron modificationpotassium activationcarbon dioxide adsorptioninżynieria chemicznaArticle10.3390/ma16155227OPUS 17 grant 2019/33/B/ST8/02044.
