Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

open access: yesCarbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

Process engineering with planetary ball mills

Chemical Society Reviews, 2013
Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus ...
