要旨

The development of structured catalyst supports to promote chemical process intensification is of great interest, and porous activated carbon (AC) is an excellent material to overcome this challenge. In addition, the current increasing hydrogen demand and its limitations in terms of transportation and storage require the development of novel approaches for the application of hydrogen. In this study, highly porous and robust 3D-printed patterned AC-based architectures were additive manufactured using the direct ink writing technology. Different AC inks containing a boehmite gel with no organic additives were rheologically characterized to select the most suitable ink for building AC supports, which were thermally treated to promote solid–solid contacts and increase their robustness (strength of ∼0.5 MPa) while maintaining a high porosity (86%). Subsequently, the AC supports were impregnated with a 5 wt% palladium (Pd) precursor to develop a 3D Pd/AC catalyst, which could generate hydrogen via the dehydrogenation of formic acid (FA), a very promising liquid organic hydrogen carrier, in a fixed-bed reactor. These 3D catalysts produced CO-free hydrogen from FA under ambient conditions with an FA conversion of 81% and hydrogen flow rate of 6 mL min−1. Furthermore, the long-term experiments in continuous mode operation showcased their good catalytic stability and recyclability. These results demonstrate that 3D Pd/AC catalysts exhibit a great potential to develop a new technology using FA as hydrogen carrier.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
