Ammonia is essential for global food production as a component of fertiliser, and a potential energy carrier in the energy transition. Electrochemical ammonia synthesis faces numerous challenges as an alternative to the carbon intensive Haber-Bosch process, including competition from hydrogen evolution, and mass transport limitations. An...

The discovery that enzymes could function efficiently in organic solvents revolutionized their use in industry but represented a change from the natural “green” solvent, water, to a host of environmentally undesirable solvents. Considerable effort is being devoted to making such processes greener again. Bio-based solvents, derived from waste...

This review article critically compares two widely used types of catalysis, chemo- and biocatalysis, and provides insights on their greenness according to specified parameters. A comparative analysis of the environmental impact of chemo- and biocatalytic oxyfunctionalisation reactions based on published experimental data reveals that both...

Heterogeneous catalysis plays a pivotal role in the current chemical and energy vectors production. Notably, to fully utilize the intrinsic activity and selectivity of a catalyst, the chemical reactor has to be designed and operated optimally to achieve enhanced heat/mass transfer, well-defined contact time of reactants, uniform flow pattern,...

Direct valorization of methane via oxidative coupling of methane (OCM) is an encouraging alternative to conventional oil-based processes for the production of light hydrocarbons (ethane and ethylene). Abundant, inexpensive simple oxides such as MgO and La<sub>2</sub>O<sub>3</sub> possess the ability to selectively activate methane. However,...

Dynamic coke-mediated dry reforming of methane (DC-DRM) is an unsteady-state strategy to overcome the limitations of co-feed operation, including the fast deactivation of the catalysts and the loss of valuable H<sub>2</sub> in the reverse water gas-shift reaction. This paper proves the feasibility of DC-DRM on Ni-based catalytic systems,...

Aromatic aldehydes are important aromatic compounds for the flavour and fragrance industry. In this study, a parallel cascade combining aryl alcohol oxidase from Pleurotus eryngii (PeAAOx) and unspecific peroxygenase from the basidiomycete Agrocybe aegerita (AaeUPO) to convert aromatic primary alcohols into high-value aromatic aldehydes is...

The redox balance in tumor and diseased cells often leads to the production of reactive oxygen species (ROS). Many ROS-responsive materials based on sulfur oxidation have been reported with the goal of achieving controlled delivery at the tumor. However, these materials often lack responsiveness to low ROS concentrations present in the tumor...

Rational plastic recycling is critical for addressing the environmental challenges associated with plastic waste. Among the various recycling methods, chemical recycling, particularly via homogeneous catalysis, holds promise for converting plastic waste into valuable products. Post-consumer polymer wastes could present a challenge for...

Designing a simple, yet representative reaction network for subsequent micro-kinetic analysis is important for limiting the cost of evaluation and ensuring model solvability. This is currently achieved by employing sensitivity analysis over a comprehensive reaction network (CRN) to screen reaction species. However, as a reaction network is...

The growing demands for sustainable chemical technologies have prompted a wave of searching new catalysts based on earth-abundant metals. In the field of (de)hydrogenation catalysis, however, the huge performance gap is commonly seen between the 3d-metal-based catalysts and their noble metal counterparts, which largely hampers their practical...

Many drugs cannot be made without homogeneous catalysis. To increase the yield of drug synthesis, the search for new catalysts continues. Computational catalysis is becoming a more prominent tool since it en- ables to screen many catalysts without performing (m)any laboratory experiments.
