Recent progress in dehydrogenation catalysts for heterocyclic and homocyclic liquid organic hydrogen carriers

Yeongin Jo et al.

Summary: Liquid organic hydrogen carriers (LOHC) are promising for H-2 storage and transportation, with the most stringent limitation being high temperatures required for the dehydrogenation reaction. Pd-based catalysts are preferred in the conversion of heterocyclic LOHC due to preferential adsorption of heteroatoms, while Pt-based catalysts dominate in the cleavage of C-H bonds for homocyclic LOHC. Efforts are needed to inhibit the generation of byproducts and improve overall performance and stability.

Mesoporous sulfur-decorated Pt-Al2O3 for dehydrogenation of perhydro benzyltoluenes: Activity-favorable adsorption of reaction species onto electron-deficient Pt atoms

Yeongin Jo et al.

Summary: The addition of sulfur to supported Pt catalysts has an impact on Pt defect sites and side reactions, which is influenced by the catalyst preparation methods. In this study, mesoporous sulfur-decorated Pt-Al2O3 catalysts with different sulfur contents were prepared using the solvent-deficient precipitation (SDP) method. The dehydrogenation of perhydro benzyltoluenes showed a volcano-shaped dependence on the sulfur content, with the maximum dehydrogenation achieved at 0.21 wt% sulfur. The best performing catalyst exhibited excellent recyclability due to negligible Pt growth and sulfur loss. The SDP method facilitated favorable contact between Pt and sulfur species, resulting in a reduction in electron density of Pt atoms. This electron-deficient Pt atoms weakened the adsorption of aromatic products and facilitated appropriate H-2 adsorption. As a result, the titled catalyst exhibited tolerance towards dehydrogenation products and lower selectivity towards the side product methylfluorene.

Sodium-Mediated Bimetallic Fe-Ni Catalyst Boosts Stable and Selective Production of Light Aromatics over HZSM-5 Zeolite

Summary: This study reports the use of Na-mediated bimetallic Fe-Ni catalyst simply mixed with HZSM-5 to enhance the stable and selective production of aromatics from syngas. The addition of Ni with Na substantially regulates iron carbide formation and suppresses carbon deposition, leading to increased selectivity to light alpha-olefins. The presence of Na weakens the Fe-Ni interaction, reduces electron transfer from Fe to Ni, and promotes the formation of lighter olefins, demonstrating the potential for developing stable and selective iron-based catalysts for the production of FT products.

Hongyi Ding et al.

Summary: Ru/Mg1-xFexO catalyst, prepared by hydrogen reduction of MgFeRu-LDHs precursor, shows structure and performance affected by reduction temperature. The catalyst reduced at 300 degrees C exhibits high catalytic activity for ethanol oxidation, possibly due to the roles of MgO, ruthenium, and FeOx in breaking bonds and promoting catalytic cycle. The confinement effect enhances effective contact between active site and substrate for improved O-2 activation and ethanol adsorption.
