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 ...

Coupled Chemical and Mechanical Control of the Pore Size in Carbon Honeycomb Membranes for Water Desalination

Advanced Materials Interfaces, EarlyView.
ABSTRACT The advancement of 3D carbon nanostructures for next‐generation desalination membranes is hindered by limited control of the pore size to ensure effective salt rejection. Chemical functionalization and mechanical modification are known approaches to address the problem, while the combined effect of the two approaches remains unexplored.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Analysis of the influence of fusion synthesis parameters on the SO2 sorption properties of zeolites produced out of fly ash

E3S Web of Conferences, 2016
Fly ash zeolites are interesting alternative for zeolies produced out of pure chemicals as well as for natural zeolites. It can be applied as SO2 sorbents out of flue gases. In the work the experiments were aimed at investigation of SO2 sorption capacity

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
