Tailoring of Waste‐Derived CO2 Adsorbents From the Perspective of Apparent and Intrinsic Property Regulation

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT The conversion of waste materials into solid CO2 adsorbents is a promising strategy for carbon capture and waste management. In this review, we discuss recent advances in the preparation and modification of waste‐derived CO2 adsorbents, including carbon‐based materials, zeolites, metal–organic frameworks, layered double hydroxides, CaO, and ...

Phlogopite Mica Under Acidic and Alkaline Conditions: Reactivity and Silicate Gel Formation

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Alkali‐activated materials (AAMs) produced using industrial residues offer a sustainable alternative to Portland cement, the production of which contributes nearly 8% of global CO2 emissions. However, commercial sodium silicate, commonly used as an activator, remains costly and energy‐intensive to produce, motivating the development of ...

Effects of three different types of fibers and dosage on the properties of alkali-activated copper slag–slag cementitious materials

Scientific Reports
The use of copper slag instead of part of the slag to prepare alkali-activated cementitious materials can achieve the resource utilisation of copper slag, but alkali-activated copper slag–slag composite cementitious materials have the disadvantages of ...
