Calcination-regulated Microstructures of Donor-Acceptor Polymers towards Enhanced and Stable Photocatalytic H2O2 Production in Pure Water.

Angewandte Chemie, 2022
Regulating molecular structure of donor-acceptor (D-A) polymer is a promising strategy to improve photoactivity. Herein, a porous nanorod-like D-A polymer is synthesized via a strategy of supramolecular chemistry combined with subsequent calcination ...

Solid‐State Reaction Heterogeneity During Calcination of Lithium‐Ion Battery Cathode

Advances in Materials, 2022
During solid‐state calcination, with increasing temperature, materials undergo complex phase transitions with heterogeneous solid‐state reactions and mass transport. Precise control of the calcination chemistry is therefore crucial for synthesizing state‐

Mechanism of calcination modification of phosphogypsum and its effect on the hydration properties of phosphogypsum-based supersulfated cement

, 2020
Supersulfated cement (SSC) is a kind of environment-friendly and energy-saving cement, which is almost entirely made of industrial waste and could consume a lot of phosphogypsum (PG), which has great potential for industrial application.

Synthesis of eggshell derived hydroxyapatite via chemical precipitation and calcination method

, 2021
It had been reported that around 250, 000 tons of eggshells waste were produced annually worldwide. It is possible to transform the eggshell wastes to useful biomaterials such as hydroxyapatite (HAp).

Effect of calcination temperature on the crystallite size, particle size and zeta potential of TiO2 nanoparticles synthesized via polyol-mediated method

Materials Today: Proceedings, 2020
TiO2 nanoparticles (anatase and rutile) were prepared by polyol-mediated synthesis technique using titanium (IV) butoxide as titanium source, acetone as oil phase and ethylene glycol as the stabilizer. The prepared samples were dried in oven at 80 °C for

Calcination of phosphates: reactivity of calcined phosphate

Powder Technology, 1980
Abstract Detailed investigations of the effect of physical, chemical and mineralogical changes in calcined phosphate rocks on its chemical reactivity were carried out. It was found that the presence of CaCO 3 and/ or CaO decreases the chemical reactivity of phosphates by consuming the active reagent in the reactivity test.
