The simultaneous decomplexation of Cu-EDTA and electrodeposition recovery of Cu(2+) ions was attempted in a photoelectrocatalytic (PEC) system using TiO2/Ti as the anode and stainless steel as the cathode. At a current density of 0.5 mA/cm(2), removal efficiencies of 0.05 mM Cu-EDTA by photocatalysis, electrooxidation, and PEC processes were determined to be 15, 43, and 72% at 3 h, respectively...

Nanoporous Pt-Co alloy nanowires were synthesized by electrodeposition of Co-rich Pt(1)Co(99) alloy into anodic aluminum oxide (AAO) membranes, followed by a dealloying treatment in a mild acidic medium. These nanowires consist of porous skeletons with tiny pores of 1-5 nm and crystalline ligaments of 2-8 nm. Morphological and compositional evolutions of the porous Pt-Co nanowires upon dealloyi...

Rechargeable aqueous Zn/MnO2 battery chemistry in a neutral or mildly acidic electrolyte has attracted extensive attention recently because all the components (anode, cathode, and electrolyte) in a Zn/MnO2 battery are safe, abundant, and sustainable. However, the reaction mechanism of the MnO2 cathode remains a topic of discussion. Herein, we design a highly reversible aqueous Zn/MnO2 battery w...

A high full-electrode basis capacity secondary battery anode consisting of a template-free 3D nanostructured Fe3O4/C composite is presented. On a full electrode basis, the nanocomposite exhibits attractive electrochemical performance including a volumetric capacity of 1064 mAh cm(-3), which significantly exceeds both the practical (≈300 mAh cm(-3)) and theoretical (837 mAh cm(-3)) capacity of a...

Lean-zinc anode is a promising configuration that can eliminate the trade-off of energy density and cycle lifetime zinc metal (Zn0) batteries. However, there are rare investigations lean-Zn designs it remains grand change to sustain high reversibility under lean conditions. Herein, design based on hierarchical zincophilic cobalt (Co0) nanowire-decorated carbon host, which derived from ZnCo bime...

Porous- and hollow-structured LiNb3O8 anode material was prepared by a hydrothermal-assisted sintering strategy for the first time. The phase evolution was studied, and the formation mechanism of the porous and hollow structure was proposed. The formation of the unique structure can be attributed to the local existence of liquid phase because of the volatilization of Li element. As the anode ma...

Deep eutectic solvents (DESs) have emerged as an alternative for conventional ionic liquids in aluminum batteries. Elucidating DESs composition is fundamental to understand electrodeposition the battery anode. Despite numerous experimental efforts, speciation of these remains elusive. This work shows how ab initio molecular dynamics (AIMD) simulations can shed light on DESs. For particular exam...

This paper presents a detailed description of phase-field models electrodeposition in lithium-anode batteries, along with underlying assumptions and parameters commonly employed. We simulate the coupled electrochemical interactions during battery charge cycle using finite elements on open-source packages, allowing for parallel computation time step adaptivity. compare conventional free energy g...
