Potential pathways for CO utilization in sustainable aviation fuel synthesis.

The development of sustainable aviation fuels (SAFs) is a must for the decarbonization of the aviation industry. This paper explores various pathways for SAF production, focusing on innovative catalytic processes for the utilization of CO as a potential feedstock. Key pathways analyzed include the Modified Fischer-Tropsch Synthesis (MFTS), methanol synthesis, and subsequent transformations of methanol into hydrocarbons (MTH), aromatics (MTA) and olefin oligomerization.

Engineering Metal-MOF Interfaces for Selective CO₂ Hydrogenation to Methanol.

The hydrogenation of CO₂ to methanol is a promising pathway toward sustainable fuel production and carbon recycling. A key factor in the efficiency of this process lies in the interaction between the metal catalyst and its support. Metal-Organic Frameworks (MOFs) have emerged as highly effective platforms due to their tunable structures, large surface areas, and ability to form stable interfaces with single-atom metals or metal nanoparticles.

Highly Dispersed Pd@ZIF-8 for Photo-Assisted Cross-Couplings and CO to Methanol: Activity and Selectivity Insights.

Our study unveils a pioneering methodology that effectively distributes Pd species within a zeolitic imidazolate framework-8 (ZIF-8). We demonstrate that Pd can be encapsulated within ZIF-8 as atomically dispersed Pd species that function as an excited-state transition metal catalyst for promoting carbon-carbon (C-C) cross-couplings at room temperature using visible light as the driving force. Furthermore, the same material can be reduced at 250 °C, forming Pd metal nanoparticles encapsulated in ZIF-8.

Reactive Infiltration: Effects of Different Parameters.

Currently, the production of complex SiC and SiC/SiC parts through reactive infiltration is one of the most widely used technologies, due to its versatility and cost-effectiveness compared to more conventional technologies such as Hot Isostatic Pressing (HIP). This technology, while widely adopted, still faces some debate regarding the mechanisms of infiltration. Questions persist about what determines how infiltration occurs and whether the process is governed by physics (flow dynamics) or chemistry (reactions at the triple line (LT: (contact line between the solid, liquid and gas phases)).

Copper nanoparticles encapsulated in zeolitic imidazolate framework-8 as a stable and selective CO hydrogenation catalyst.

Metal-organic frameworks have drawn attention as potential catalysts owing to their unique tunable surface chemistry and accessibility. However, their application in thermal catalysis has been limited because of their instability under harsh temperatures and pressures, such as the hydrogenation of CO to methanol. Herein, we use a controlled two-step method to synthesize finely dispersed Cu on a zeolitic imidazolate framework-8 (ZIF-8).
