Mechanochemical activation can be defined as a process able to induce structural disorder
through intensive grinding. In certain conditions, it may increase the chemical reactivity of …

Acid activation is a chemical treatment traditionally used on clays, typically bentonites in
hydrochloric or sulphuric acid, to obtain partly dissolved materials with enhanced surface …

Historically, clay mineral catalysts have found industrial applications since the early 1930s.
However, inherent limitations such as impurities, porosity, low surface area and acidity …

Kaolin from a Serbian deposit, characterized by high content of impurities, such as mica and
quartz, disordered kaolinite and high specific surface area, was subjected to thermal and …

Coal gangue, a type of kaolinite clay in coal measures, is one of the largest categories of
solid industrial wastes in China. Alumina extraction from coal gangue could offer an …

This study presents novel characterisation techniques to evaluate the effects of mechanical
activation (MA) on the kaolinite structure. MA was achieved with a planetary ball mill at …

Cr (VI) has great solubility and mobility in water, and is a class of highly toxic heavy metals.
Illite modified gC 3 N 4 (IL-CN) materials were successfully synthesized and their …

Planetary ball mill is used to process kaolinite clay powder under a commercial name of
proclay kaolinite. Influence of milling time on structure and thermal behavior of proclay …

Acid activation is a common chemical modification of clays, usually bentonites, with a hot
solution of a mineral acid (typically HCl or H 2 SO 4), and it is used for both scientific and …

A novel kaolinite/gC 3 N 4 (KA/CN) composite with enhanced visible light-driven
photocatalytic activity was prepared through a simple mechanochemical method. The …
