Summary: A simple wet chemical method was used to prepare two-dimensional transition metal carbides (MXene), and Pd metal nanoparticles were loaded on its surface to catalyze the dehydrogenation of formic acid. The prepared Pd/PDA-MXene catalyst exhibited excellent catalytic activity in formic acid decomposition process, and maintained stable activity in five consecutive catalytic cycles.

Summary: This research presents a method of hydrogen production from formic acid using fluidized bed technology. A core-shell catalyst was developed by applying a Ni layer on cenospheres via gaseous deposition. The efficiency of formic acid decomposition was tested continuously in the range of 200-500°C. An analytical method based on infrared spectroscopy was developed for the continuous monitoring of product concentration in the gas phase. The proposed solution in a fluidized bed was compared with other methods, showing advantages such as on-demand hydrogen generation, use of biomass or CO2 as an energy carrier, process simplicity, easy temperature control, repeatability, scalability, continuous monitoring, and high hydrogen generation efficiency per unit volume.

Summary: Research has shown that PyCoPc/GO fabricated from cobalt-phthalocyanine and graphene oxide exhibits efficient hydrogen evolution reaction in alkaline media. The active area of the catalyst was controlled through π-π stacking interaction between GO and PyCoPc, leading to the development of a highly efficient catalyst for hydrogen evolution.

Summary: Three imidazole-based hybrid materials, IGOPS, IPS, and impyridine@SiO2 nanohybrids, were prepared for H-2 generation from formic acid. The immobilization of imidazole derivative onto SiO2 affected its surface area, pore volume, and particle size distribution. The [Fe2+/IGOPS/PP3] heterogeneous catalyst showed superior activity but low recyclability, while [Fe2+/IPS/PP3] demonstrated high stability and considerable performance after three consecutive uses. The reduced recyclability of [Fe2+/IGOPS/PP3] and [Fe2+/impyridine@SiO2/PP3] nanohybrids was due to the reductive cleavage of their C-O-C bonds during catalysis.

Summary: The development of a new electrolytic water hydrogen production coupling system is essential for efficient and low-cost hydrogen production. In this study, a green and efficient electrocatalytic biomass to formic acid (FA) coupled hydrogen production system was created. The system showed a high yield of glucose to FA (62.5%) and a low electrical consumption (2.9 kWh Nm(-3) (H-2)). This work provides a promising direction for low-cost hydrogen production coupled with efficient biomass conversion.

Summary: Formic acid can be used as a hydrogen donor in hydrogen production and transfer reactions catalyzed by metal and metal-complex catalysts. This review highlights the potential of heterogeneous catalysts with single metal atoms stabilized by pyridinic nitrogen atoms on the edge or vacancy sites of graphene sheets. Understanding the nature and coordination of single-atom active sites is crucial for enhancing the performance of catalysts in these reactions, with the aim of developing novel and efficient catalysts.

Summary: We developed an efficient process for producing hydrogen gas from aqueous ethylene glycol (EG) at 90-160 degrees C over a ruthenium catalyst. The role of reaction temperature and base concentration was found to be critical in achieving a high yield of H2. The ruthenium catalyst exhibited high long-term stability, generating ca. 290 L of H2 per gram of Ru with a yield of 1035 L of H2 per L of ethylene glycol.

Summary: The study demonstrates that the addition of formic acid in the hydrothermal liquefaction process of municipal sludge at high loading can significantly improve the yield and quality of biochar, leading to efficient energy recovery. Additionally, the synergistic use of heterogeneous catalysts and formic acid can also enhance the yield and quality of biochar, although carbon fouling on the catalyst's surface may occur at higher concentrations.
