Synthesis and Evaluation of Novel Ruthenium on Dysprosium‐Praseodymium Oxide Catalysts for Ammonia Synthesis and Decomposition in the Hydrogen Energy Vector Transition

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
Adding dysprosium to a praseodymium oxide support led to an increase in ammonia decomposition activity, ammonia synthesis activity, improved catalyst stability, and improved electron transfer to the ruthenium. Currently, there is a push to reduce reliance on hydrocarbon fuels for energy storage by using hydrogen carriers.

From Citrus to Cymene: Understanding the Hydrothermal Conversion of Limonene

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
When life gives you limonene… Hydrothermal conversion and pyrolysis of limonene give two distinct sets of products, arising from differing reaction cascades. While p‐cymene dominates in the presence of water, indicative of an isomerisation/aromatisation pathway, pyrolysis favours cracking and loss of carbon affording an m‐xylene rich aromatic mix.

Electrodeposited MnCo and MnNiCo Spinels for Anion Exchange Membrane Direct Ammonia Fuel Cell Cathodes: An Alternative to Platinum

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
Electrodeposited MnCoOX and MnNiCoOX spinels on Ni foam are evaluated as binder‐free, platinum group metal‐free cathodes in direct ammonia fuel cells. MnCoOX matches and surpasses Pt in oxygen reduction performance while tolerating ammonia crossover, whereas Ni incorporation dilutes the active Co–Mn sites and degrades performance.
