The CO2 adsorption performances of a Linde-Type A (LTA) zeolite and natural Clinoptilolite (Clino) zeolite, both in shaped form, were investigated as such or after an ion-exchange procedure compared to assess their potential application solid adsorbents for Carbon Capture Storage (CCS). samples characterized following multi-technique approach. Their structural textural properties evaluated investigate the accessibility different ions present inside microporous structure strength interaction...
Abstract The diffusion of saturated and unsaturated hydrocarbons is fundamental importance for many zeolite‐catalyzed processes. Transport small alkenes in the confined zeolite pores can become hindered, resulting a significant impact on ultimate product selectivity separation. Herein, intracrystalline light olefin/paraffin through 8‐ring windows SAPO‐34 characterized by complementary set first‐principle molecular dynamics simulations, PFG‐NMR experiments, pulse‐response temporal analysis...
Cu-exchanged zeolites are widely studied materials because of their importance in industrial energetic and environmental processes. Cu redox speciation lies at the center many these processes but is experimentally difficult to investigate a quantitative manner with regular laboratory equipment. This work presents novel technique for this purpose that exploits selective adsorption CO over accessible Cu(I) sites quantify them. In particular, isothermal volumetric measurements performed 50 °C...
Electrochemical reduction of CO2 (CO2RR) is expected to play a key role among the various strategies being explored limit global warming. In this scenario, Layered Double Hydroxides (LDHs) are emerging as promising class electrocatalysts replace most used noble metals. work three Zn-Al LDH with different Zn2+/Al3+ ratio were synthesized and characterized by means XRD, STEM-EDX HR-TEM. Their suitability for CO2RR CO was assessed custom-made three-compartment cell, showing an increase in...
Supported metal nanoparticles may undergo adsorbate-induced phenomena, with evident consequences for their performance in catalytic applications. CO-induced surface phenomena involving Pd have been documented mostly at high temperatures. In this work, we report an unusual step-shaped CO adsorption isotherm 30 °C on Pd/Al2O3, associated unexpected increase the heat of and a modification relative abundance different Pd-carbonyl species. These three independent observations can be reconciled by...

A combined use of structural, textural and spectroscopic techniques serve as a photographic lens to gain insights into the mixed-linker Ce-UiO-67 MOFs that we have successfully synthesised.
Ce metal-organic frameworks (MOFs) have recently gained scientific interest, since cerium is the most abundant rare-earth element in Earth crust, and their synthesis has some advantages, including first of all its redox activity, high porosity these crystalline materials, cost-effectiveness. In particular, Ce(IV)-based MOFs, such as Ce-UiO-66 Ce-UiO-67, are synthesised under mild conditions. For applications, presence functional groups needed: this context, linkers containing...
Mittels eines synergetischen theoretischen und experimentellen Ansatzes zeigen Veronique Van Speybroeck et al. in ihrem Forschungsartikel auf S. 10104, dass die Gegenwart von Brønsted-Säurezentren Ethen-Diffusion durch Käfige H-SAPO-34 fördert, während Ethan-Diffusion der Dichte Säurezentren unbeeinflusst bleibt. Die Wechselwirkung Ethen mit den (gelbe Punkte) erleichtert Diffusion Katalysator führt zu einem kürzeren Diffusionsweg (blauer Weg) im Vergleich Ethan, das einer zufälligen...
