Repurposing Mining and Metallurgical Waste as Electroactive Materials for Advanced Energy Applications: Advances and Perspectives

Catalysts, Journal Year: 2023, Volume and Issue: 13(9), P. 1241 - 1241

Published: Aug. 26, 2023

Developing cost-effective electroactive materials for advanced energy devices is vital the sustainable development of electrochemical conversion/storage systems. To reduce fabrication cost (electrocatalysts and electrodes), growing attention has been paid to low-cost precursors. Recently, mining metallurgical waste used design materials, which shows great economic environmental benefits. Herein, current achievements in applications waste-derived fields (batteries, supercapacitors, fuel cells, small-molecule electro-conversion) are comprehensively analyzed. The waste-to-materials conversion methods materials’ structure–performance relationships emphasized. In addition, perspectives related further high-performance pointed out.

Novel dual-phase ceramic membrane for sustainable oxygen separation

Sustainable Horizons, Journal Year: 2024, Volume and Issue: 10, P. 100095 - 100095

Published: Feb. 23, 2024

Mixed ionic–electronic conducting (MIEC) perovskite oxide membranes are greatly required in fields of oxygen separation. In this study, Gadolinium-doped Cerium (GDC) and La2NiO4 (LNO) powders prepared into dual-phase by ball-milling sintering. The mixed show a distorted phase with orthorhombic structure cubic structure. For permeability membranes, the fluxes increase enhancement temperatures or He sweep gas flows. effects four doping ratios (10 %, 20 30 40 %) on discussed. Compared LNO membrane, permeation varying degrees improvement. And, optimal ratio is wt.%. maximum flux ∼3.53 mL·min−1·cm−2 all test conditions. To further investigate influence different conditions permeability, Arrhenius activation energy theory, kinetic analysis, improvement factor introduced to support hypothesis. Simultaneously, have excellent tolerance CO2 atmosphere. long-time stability (∼1200 min) under atmosphere recovery capability can endow membrane great potential for numerous applications.
