| Abstract: | Additive manufacturing (AM) of advanced functional ceramics using preceramic polymers (PCPs) is gaining attention due to its processability and tailorable properties. A photosensitive resin with iron-modified polysiloxanes was developed for vat photopolymerization (VPP) to create porous SiOC(Fe) catalytic supports with magnetic heating capability. Ferric acetylacetonate and ferrocene were examined as iron precursors, leading to the formation of Fe-based magnetic particles (α-Fe, Fe3C, FexSiy) within the silicon oxycarbide (SiOC) ceramic matrix after pyrolysis at 800 to 1500 °C. Depending on the Fe-based precursor used and the applied pyrolysis temperature, the obtained monoliths exhibited magnetic nanoparticle (MNP) contents ranging from 0.9 to 7.9 wt%, with particle sizes from 17 to 96 nm. The monolithic catalyst supports fabricated from ferric acetylacetonate modified PCP-based resin formulations, pyrolyzed at 900 °C, exhibited the highest specific absorption rate and resulted in magnetic heating up to 200 °C at an applied external magnetic field of 60 kA·m−1. While catalyst supports fabricated from ferrocene modified PCP-based resin formulations had lower heating capabilities, they offered better printability and higher ceramic yield. In situ formed MNPs impart magnetic properties advantageous for catalyst support heating, highlighting AM’s design flexibility and PCPs’ role in creating tailored, lightweight structures with controlled porosity. |
