New paper published on nitrate reduction in Advanced Functional Materials

In a new collaborative paper in Advanced Functional Materials, we report an exfoliation-induced electrochemical reconstruction strategy that transforms CuCoAl layered double hydroxides into an amorphous/crystalline heterostructure for efficient nitrate reduction to ammonia. The reconstructed catalyst combines metallic Cu, crystalline Co(OH)2, and amorphous CoOOH, enabling high ammonia selectivity, excellent Faradaic efficiency, and strong cycling stability. Beyond […]

New paper published in Energy Advances on lithium-ion extraction with lithium manganese oxide

New collaborative work with University of Granada (Silvia Ahualli) published in RSC Energy Advances. This study explores an electrochemical route for selective lithium recovery from saline water using lithium manganese oxide, whose spinel structure can reversibly intercalate lithium ions under controlled cell voltages. By combining lithium manganese oxide with polyelectrolyte coatings, the work links ion […]

New paper published on Li-ion extraction from battery shredder solutions for recycling in ChemSusChem

New paper published on electrochemical Li-ion extraction in the context of lithium-ion battery recycling in ChemSusChem. In this collaborative work with Fachhochschule Münster, we demonstrate an electrochemical route to recover lithium ions directly from real battery recycling process water generated during the wet shredding of lithium iron phosphate batteries. Using an LFP-based selective desalination cell, […]

New paper published and featured on the front cover in Energy Advances on modified nanoporous carbons for lithium-sulfur batteries

New collaborative paper published in RSC Energy Advances. This study addresses one of the central challenges of lithium-sulfur batteries: capacity fading caused by polysulfide migration and incomplete confinement in carbon hosts. The team engineered a microporous carbon with a pore size of about 1.2 nm to host both short- and long-chain polysulfides, then further tuned […]

New paper published in Battery Energy on intraparticle effects on lithium-sulfur battery performance

New collaborative paper published in Battery Energy on “Intraparticular inhomogeneity limits capacity in lithium sulfur batteries with carbonate electrolyte”. This work shows that the performance of lithium-sulfur batteries with carbonate electrolytes is strongly governed by how the cathode-electrolyte interphase (CEI) forms inside nanoporous carbon host particles during the first discharge. Using cryogenic electron microscopy together […]

New paper published in Polymer Chemistry on cellulose-based membranes

New paper published in Polymer Chemistry on cellulose-based membranes. The collaborative work demonstrates how tailored linear and star-shaped block copolymers can be assembled around cellulose fibers to create hierarchical porous structures, which can then be chemically modified to adjust surface polarity, wettability, and water permeance. This approach opens a versatile route toward functional, cellulose-based porous […]

New paper published in Battery Energy on mixed transition metal oxalates for lithium-ion batteries

In our work, we have developed a new multi-phase transition metal oxalate anode material for lithium-ion batteries by combining five transition metals in a simple co-precipitation process, creating a structure that improves both charge transport and structural stability during cycling. The best-performing composition, TMOx-2, showed strong long-term performance, retaining 827 mAh/g after 400 cycles at […]
