Photothermal CO2 Hydrogenation: Reactions, Mechanisms, and Catalyst Design

Carbon Energy, EarlyView.
Reactions, mechanisms, and catalyst design for photothermal CO2 hydrogenation. ABSTRACT Photothermal CO2 hydrogenation has attracted extensive attention because it provides a green and sustainable approach to fuel and chemicals production. The photothermal catalyst plays a critical role in CO2 conversion through a range of reactions.

Microstructural characterization of in-situ MgAl2O4 nanoparticles reinforced Al–2Mg–1Si composite produced using the ultrasonic assisted stir casting process

Journal of Materials Research and Technology
The ceramic particle reinforced Aluminium Matrix Composites (AMCs) lead to a reduction in ductility due to the restricted plastic flow of the matrix. The present work shows an enhancement in tensile properties without considerable loss in ductility by ...

Synthesis of MgO Doped with CoO/MgAl2O4, NiO/MgAl2O4, and CuO/MgAl2O4 in a Single Pot for Efficient Dye Adsorption

Inorganics
A simple method employing dextrose as a capping agent was adopted for making MgAl2O4@MgO (AM), 5%NiO-MgAl2O4@MgO (AMNi), 5%CoO-MgAl2O4@MgO (AMCo), and 5%CuO-MgAl2O4@MgO (AMCu) nanocomposites. The average particle sizes, determined via SEM, were in the range of 21.6–51.4 nm, 9.8–13.8 nm, 19.1–32.2 nm, and 9.2–31.2 nm for AM, AMCu, AMNi, and AMCo ...

Structural characteristics of MgAl2O4 spinel [PDF]

, 2023
Magnesium aluminate spinel (MgAl2O4) is a material with good mechanical, chemical, and thermal properties, low dielectric permeability and loss tangent. Based on those properties, MgAl2O4 has found a significant application in refractory ceramics, ceramics windows, integrated electronic devices, etc.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.
