Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Magnetic field‐assisted concentration swing adsorption for CO2 capture over Fe3O4/fibrous nanosilica‐PEI adsorbent

open access: yesAIChE Journal, EarlyView.
Abstract Magnetic field‐assisted concentration swing adsorption (CSA) provides an electrification‐compatible alternative to conventional temperature swing adsorption (TSA) by enabling rapid heating/cooling and energy‐efficient regeneration under near‐isothermal conditions, thereby eliminating the need for sensible heat input.

Zeolite-Modified Fischer-Tropsch Synthesis

open access: yes, 2011
The improvement of the gasoline selectivity and quality with the addition of HZSM-5 to the Fe-FT process is evident from literature. The catalytic performance of the combined Fe-FT/HZSM-5 system has been observed to decline with time-on-stream ...

Topology‐Aware Machine Learning for High‐Throughput Screening of MOFs in C8 Aromatic Separation

open access: yesAdvanced Intelligent Discovery, EarlyView.
We screened 15,335 Computation‐Ready, Experimental Metal–Organic Frameworks (CoRE‐MOFs) using a topology‐aware machine learning (ML) model that integrates structural, chemical, pore‐size, and topological descriptors. Top‐performing MOFs exhibit aromatic‐enriched cavities and open metal sites that enable π–π and C–H···π interactions, serving as ...

Zeolite deactivation during hydrocarbon reactions: characterisation of coke precursors and acidity, product distribution

open access: yes, 2008
The catalytic conversion of hydrocarbons over zeolites has been applied in large scale petroleum-refining processes. However, there is always formation and retention of heavy by-products, called coke, which causes catalyst deactivation. This deactivation

The Process Transport of Drying Corn With Mixed-Adsorption Drying [PDF]

open access: yes, 2012
Mixed-adsorption drying with adsorptive material such as zeolite is an option to enhance the performance of drying corn. In this case, zeolite and seeds are mixed and fluidized by warm air as drying medium.

Photolytic and thermolytic decomposition products from iron pentacarbonyl adsorbed on Y zeolite [PDF]

open access: yes, 1985
Zeolite supported iron systems obtained by photolysis and thermolysis of Fe(CO)5/Na---Y adducts are characterized via evaluation of the respective magnetic isotherms taken with a FONER magnetometer at T = 4.2 K.

Acidity of Zeolites

open access: yes
Zeolites, known for their crystallinity and porosity, exhibit versatile acid functionalities, making them valuable industrial catalysts. This chapter discusses the acidity of zeolites, including Brønsted and Lewis acids, and their variations. It focuses on the principal methodologies for adjusting zeolite acidity, including isomorphous substitution ...
