The efficient enhancement of mass and heat transfer, as well as mechanical stability, has attracted particular interest for fixed-bed reactors in practical applications. Herein, a monolithic CuNi alloy catalyst with ordered microchannels composed of a triply periodic minimal surface (TPMS) was designed and fabricated using three-dimensional (3D) printing technology, which boosted the highly efficient and robust reverse water-gas shift (RWGS) reaction. The unique TPMS lattice structure enabled the monolithic CuNi catalyst to enhance mass and heat transfer efficiencies, resulting in a significantly improved catalytic performance for the RWGS reaction compared with the monolithic catalyst with a honeycomb structure or the traditional CuNi/Al2O3 catalyst. Furthermore, the 3D-printed monolithic CuNi catalyst exhibited excellent catalytic and mechanical stability at high reaction temperatures. The simple and cost-effective fabrication of conductive metal catalysts with tunable 3D multichannel architectures opens new opportunities in developing heterogeneous catalysts for fixed-bed reactors.

Journal of Materials Chemistry A

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.
