Fecha de publicación: | 1-jul-2023 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Catalysts 13(7): 1039 (2023) | Resumen: | This work shows a new method for the preparation of 100% carbon-structured devices. The method is based on resorcinol-formaldehyde polymerization, using starch as a binder with the addition of a certain amount of external carbon source before polymerization. Molds obtained by 3D printing are used to shape the structured devices in the desired shape, and the ultimate pyrolysis step consolidates and produces the carbonaceous devices. The proposed method allows obtaining supports with different textural and surface properties varying the carbonaceous source, the solvent, or the pyrolysis conditions, among other factors. The as-obtained devices have demonstrated their usefulness as palladium supports for the gas-phase formic acid dehydrogenation reaction. The monolith shows a high conversion of formic acid (81% according to H2 production) and a high selectivity towards hydrogen production at mild temperatures (80% at 423 K). | Versión del editor: | https://doi.org/10.3390/catal13071039 | URI: | http://hdl.handle.net/10261/330403 | DOI: | 10.3390/catal13071039 | E-ISSN: | 2073-4344 |
