Upcycling Spent Lithium Iron Phosphate Battery Into Fe‐CN3P Single Atom Catalyst for Environmental Remediation

open access: yesAngewandte Chemie, Volume 138, Issue 15, 6 April 2026.
Electrochemical (EC) advanced oxidation enables near‐complete lithium and iron recovery from spent lithium iron phosphate batteries, while simultaneously transforming leach residues into a high‐performance P, N‐doped single‐atom Fe catalyst. The reconstructed Fe–CN3P catalyst exhibits exceptional peroxymonosulfate (PMS) activation and rapid bisphenol A

Metabolomic Analysis Reveals Contributions of Citric and Citramalic Acids to Rare Earth Bioleaching by a Paecilomyces Fungus

open access: yesFrontiers in Microbiology, 2020
Conventional methods for extracting rare earth elements from monazite ore require high energy inputs and produce environmentally damaging waste streams. Bioleaching offers a potentially more environmentally friendly alternative extraction process.

Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction

open access: yesAngewandte Chemie International Edition, EarlyView.
Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

Bacterial leaching of an Indonesian complex copper sulfide ore using an iron-oxidizing indigenous bacterium

open access: yesMicrobiology Indonesia, 2018
The bioleaching of an Indonesian complex copper sulfide ore was studied in shake flasks over a period of 14 days using an iron-oxidizing indigenous bacterium at room temperature (28 oC) and various pulp densities (5% and 20%). The bioleaching suspensions

Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal
