Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...

Lattice Distortion‐Driven Metal Exsolution in Perovskite Oxides

Advanced Science, EarlyView.
This study elucidates the mechanism of lattice distortion‐driven exsolution through a combination of computational simulations and experimental approaches. Lattice distortion facilitates the formation of oxygen vacancies and subsequent metal segregation, thereby enhancing the exsolution behavior.

CO2 Adsorption Capacities in Zeolites and Layered Double Hydroxide Materials

Frontiers in Chemistry, 2019
The development of technologies that allow us to reduce CO2 emissions is mandatory in today's society. In this regard, we present herein a comparative study of CO2 adsorption over three types of materials: zeolites, layered double hydroxides (LDH), and ...

A Pore or not a Pore? Understanding Pore Size Distributions of Non‐Graphitic Carbon and Atomically‐Dispersed M‐N‐C Materials

Advanced Science, EarlyView.
Gassorption analysis of in‐plane functionalized carbons reveals small, uniform ultramicropore signatures as potential artefacts of specific adsorption of the probe gases. Low‐pressure Langmuir fitting links these features to distinct functionalities via adsorption energies, enabling straightforward quantification of otherwise inaccessible surface‐site ...

Exceptional CO2 Hydrogenation to Gasoline Enabled by GaZrOx/Ga‐ZSM‐5 Tandem Catalyst

Advanced Science, EarlyView.
A GaZrOx/Ga‐ZSM‐5 tandem catalyst achieves 17.2% CO2 conversion with 83.2% C5+ selectivity and >400 h stability relies on optimized O‐vacancies and Ga‐H coverage for CO2 hydrogenation. ABSTRACT CO2 hydrogenation to gasoline offers a promising route for addressing energy challenges and enabling the effective utilization of carbon resources. However, the

Mechanisms of formation of extraframework Al2O3 in zeolites [PDF]

, 1997
Extraframework alumina in zeolites is considered by some authors to play a crucial role in the establishment of their reactivity. Charge transfer molecular dynamics simulations (CTMD) in the microcanonical ensemble of zeolite Y confirmed that ...

Cs+ and Sr2+ adsorption selectivity of zeolites in relation to radioactive decontamination

Journal of Asian Ceramic Societies, 2015
Zeolites are used as adsorbents of cationic elements in the radioactive decontamination process of water, soil and others. We determined Cs+ and Sr2+ adsorption selectivity of some zeolites to know effective zeolite species for the decontamination of ...

Acidity of Zeolites

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 ...
