Influence of pH tuning at the precursor-preparation process on the structural characteristics and catalytic performance of hydrothermally synthesized ZnAl₂O₄ nanoparticles

Abstract

pH tuning at the precursor-preparation process on the structural characteristics and catalytic performance of hydrothermally synthesized ZnAl 2 O 4 nanoparticles,

Catalyst supports based on ZnO–ZnAl2O4 nanocomposites with enhanced selectivity and coking resistance in isobutane dehydrogenation

“…A low surface area, which is a disadvantage of spinel materials for catalytic applications, can be improved by choosing an appropriate synthesis method. For example, ZnAl 2 O 4 can be synthesized by the solid-state reaction or the ceramic method; 14 l ,15 wet chemical routes such as the sol–gel technique, 16 precipitation or coprecipitation; 17 and other techniques, such as hydrothermal methods, 18 mechano-chemical methods, 14 g solution combustion synthesis (SCS), 19 including microwave-initialized SCS; 20 molten salts synthesis, 21 vibrational milling method, 22 etc .…”

Particle size-controlled synthesis of high-performance MnCo-based materials for alkaline OER at fluctuating potentials

“…An influence of pH on the particle size and crystallinity of metal oxide materials obtained from hydrothermal synthesis was already observed by other research groups. 38,[40][41][42] N 2 -Physisorption measurements reveal a type II isotherm after IUPAC with a small hysteresis for MnCo-pH 7 (Fig. S3 in the ESI †).…”

Influence of fabrication conditions on the structural characteristics and the magnetic properties of FeAl2O4

“…Applications of spinel materials have been widely investigated in a wide range of scientific fields, including magnetism, 4,5 catalytic chemistry, [6][7][8][9] optical science, [10][11][12] pigments, 13 and so on. In particular, catalytic applications are meaningful and promising challenges.…”
