Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Experimental Investigation on the Effect of Dry and Wet Activation Processes on the Morphological Properties of Activated Carbon Derived From Sugarcane Bagasse

Carbon Innovation, EarlyView.
Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

Chemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
