This work reviews advances in CO₂-to-DME synthesis under mild conditions, emphasizing gas and liquid-phase routes, catalyst design, and a novel methyl formate pathway, highlighting both its potential and current limitations.

The recent progresses in the ethylene conversion catalyzed by Ni-aluminosilicates, including types of catalysts depending on the support, active sites, oligomerization mechanism and kinetics and catalyst deactivation are examined in this review.

A hierarchical heterogeneous palladium on nickel foam-based catalyst system was demonstrated for the selective hydrogenation of quinoline and quinoline derivatives under low H₂ pressures, with green solvents (ethanol, ethanol water mixture).

A sulfonated carbon catalyst was rapidly synthesized via a one-pot microwave method, achieving >90% biodiesel conversion under mild conditions.

Heterometallic cooperativity can improve catalyst performance in lactide polymerisation, yet some heterocombinations do not cooperate. This work shows how the metal roles change with different heterocombinations, affecting polymerisation efficiency.

Bamboo activated carbon in bed-packed column flow system.

A stable, defect-rich peroxo-TiO₂ photocatalyst with low bandgap and high S_BET (>380 m² g⁻¹) shows high solar photocatalytic activity and regeneration.

The need for sustainable hydrogen production has driven the search for efficient, earth-abundant catalysts.

An innovative SiO₂–[PEIH]_x[POM] nanocatalyst efficiently converts fructose to HMF and oxidizes HMF to DFF, achieving a high TON of 1720 via a sustainable pathway.

Electronic tuning of the para-R group of the Ni precatalyst allows a means to regulate the branching density and the M_w of the PE. The E_1/2 value of the precatalyst has been used as a quantitative descriptor of this electronic effect.

Local confinement of the active site, estimated by CO bite angle from CO-DRIFTS, directs hydroformylation of ethylene over phosphonic acid modified Rh₁/TiO₂ catalysts.

Propane oxidative dehydrogenation with CO₂ is key for on-purpose propene production. V/CHA zeolites emerge as candidates. Insights into catalytic performance using box-and-whisker plots support data representation for catalyst design.

This study examines fructose dehydration to HMF over hydrothermally synthesized SrNb₂O₆, yielding 74.9% HMF (78.5% selectivity) via optimal acidity. The catalyst showed good recyclability, retaining stability over six runs with minor activity loss.

Different activation methods were applied to rice husk biochar from slow pyrolysis for use as sustainable catalyst support. Results show activation method greatly affects performance, with KOH activation yielding especially strong results.

Cerium oxide nanoparticles possess inherent strain, which facilitates the stabilization of various reactive oxygen species, such as hydrogen peroxide and its dissociation products, on their surfaces, thereby altering their surface activity.
