CO-Tolerant Heterogeneous Ruthenium Catalysts for Efficient Formic Acid Dehydrogenation.
Angew Chem Int Ed Engl
January 2025
The development of improved and less costly catalysts for dehydrogenation of formic acid (HCOOH) is of general interest for renewable energy technologies involving hydrogen storage and release. Theoretical calculations reveal that ruthenium (Ru) nanoparticles supported on nitrogen-doped carbon should be appropriate catalysts for such transformations. It is predicted that nitrogen doping significantly decreases the formation of CO, but at the same time increases CO tolerance of the catalysts.

- - A 3D-printing technique is used to create precursor microarchitectures that, after heating to 650 °C, transform into hierarchical 3D hollow microarchitectures (3DHMs) primarily made of TiO and inorganic stabilizers.
- - The structure features hollow beams with inner and outer diameters of approximately 80 μm and 150 μm, respectively, composed of TiO nanoparticles.
- - The study investigates the use of these 3DHMs, enhanced with α-FeO nanoparticles, for solar-driven photo-Fenton reactions to degrade organic pollutants like methyl blue and acetaminophen, demonstrating their potential for effective catalytic applications.
Article Synopsis
- A new method combines photocatalytic hydrogen generation with green enzymatic reductions, showing a significant increase in efficiency.
- The system, using Pt(x)@TiO, produces hydrogen at levels much higher than existing technologies, based on a unique photocatalytic mechanism rather than thermal reactions.
- The approach successfully synthesizes valuable compounds at low pressure and room temperature, indicating potential applications in flavors, fragrances, and pharmaceuticals.
The development of highly efficient and stable visible-light-driven photocatalysts for the removal of herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) from water is still a challenge. In this work, BiMoO (BMO) materials with different morphology were successfully prepared via a simple hydrothermal method by altering the solvent. The morphology of the BMO material is mainly influenced by the solvent used in the synthesis (HO, ethanol, and ethylene glycol or their mixtures) and to a lesser extent by subsequent thermal annealing.

However, most studies have focused solely on investigating the RWGS reaction over catalysts with high Cu and Fe loadings, thus leading to an increase in the complexity of the catalytic system and, hence, preventing the gain of any reliable information about the nature of the active sites and reaction mechanism. In this work, a CeO-supported single-atom Cu catalyst modified with iron was synthesized and evaluated for the RWGS reaction.
