Special Issue Information

Dear Colleagues,

At this time, it is of great urgency to achieve chemical processes that produce renewable emissions in whole or in part. For this purpose, green hydrogen is presented as a valuable tool for generating various organic compounds of a renewable nature, since it can be essential in hydrogenation processes of CO2 captured in any type of industrial reaction. Likewise, the hydrogenation of N2 through the Haber process or the Haber–Bosch process can be utilized to produce green ammonia, which can lead to the industrial production of multiple organic compounds of interest. Currently, the most characteristic method for obtaining green hydrogen is based on capturing it through the hydrolysis of water using renewable electricity, that is, through water electrolysis. However, given the interest in this process, we have considered publishing a Special Issue dedicated to the production of green hydrogen using the following criteria: any type of catalysis, homogeneous or heterogeneous, including photocatalysis and biocatalysis; any type of catalyst; and any type of substrate.

We look forward to receiving your contributions.

Impact of K on the Basicity and Selectivity of Pt/m-ZrO2 Catalysts for Methanol Steam Reforming with co-fed H2
by Braedon McFee, Michela Martinelli, Dali Qian, Phoenix Macfarlane, Fernanda Perez Marin and Gary Jacobs

This study investigates the effect of potassium (K) promotion on Pt/m-ZrO2 catalysts in methanol steam reforming (MSR), revealing critical insights into reaction pathways and catalyst performance. While increasing K loading reduces catalytic activity, it selectively enhances the hydrogen-producing formate dehydrogenation and de-carboxylation pathway. Structural analyses using HR-TEM and DRIFTS show that higher K concentrations block Pt sites and promote agglomeration, reshaping catalytic behavior. Notably, the 3.1% K-promoted catalyst achieves high stability at 358 °C, with a CO2 selectivity exceeding 80% and minimal methane formation, outperforming the unpromoted catalyst in terms of CO and CH4 selectivity. Temperature studies further demonstrate reduced CO selectivity at higher temperatures, highlighting distinct advantages of K-doped catalysts. These findings underscore the role of K in enhancing surface basicity and its impact on formate interaction, offering valuable insights for optimizing MSR catalysts and advancing hydrogen production technologies.

Aqueous gel-casting provides a cost-effective and scalable approach for synthesizing nano-spherical Co3O4 powders, enabling precise control over particle morphology. In this study, Co3O4 powders were prepared using this method and evaluated as a catalyst precursor for the hydrolysis of sodium borohydride (NaBH4). The effects of the monomer (acrylamide, AM)-to-metal molar ratio and initiator content (ammonium persulphate, APS) on particle size and catalytic performance were systematically explored. X-ray diffraction (XRD) analysis confirmed the formation of the Co3O4 phase at 400 °C, while transmission electron microscopy (TEM) images revealed particle sizes ranging from 16 to 85 nm, with higher AM and APS concentrations promoting finer particles. The optimized catalyst achieved a high hydrogen generation rate (HGR) of 28.13 L min−1·cat.−1, demonstrating excellent catalytic activity. Moreover, in situ-formed cobalt boride, derived from Co3O4 calcined at 600 °C for 2 h, exhibited an activation energy of 51.81 kJ mol−1, comparable to Ru-based catalysts. This study underscores the aqueous gel-casting technique as a promising strategy for synthesizing efficient and low-cost hydrogen generation catalysts, offering an alternative to noble metal-based materials.

Cleavage of C-C bonds is crucial for hydrogen production via aqueous phase reforming of biomass-derived oxygenates. In this study, the hydrogen production performance and C-C bond cleavage capacity of Ni-W/AC catalysts with varying W/Ni ratios are evaluated using ethylene glycol as a model compound. A series of APR experiments conducted suggests that Ni-0.2W/AC catalyst exhibits the highest C1/C2+ ratio of 15.87 and achieves a hydrogen yield of 47.76%. The enhanced Ni-W bimetallic interactions, which significantly improve the efficiency of C-C bond cleavage and increase catalyst activity by promoting active site dispersion, are confirmed by detailed characterization techniques. Further analysis of product distribution provides insights into the reaction pathways of ethylene glycol and the reaction mechanism for ethanol during aqueous phase reforming. All the results indicate that this catalytic reforming method effectively facilitates C-C bond cleavage and hydrogen production, contributing to a better understanding of APR mechanisms for biomass-derived oxygenates.
