2D CoFe-LDH Nanosheet-Incorporated 1D Microfibers as a High-Performance OER Electrocatalyst in Neutral and Alkaline Media

Sreenivasan Nagappan et al.

Summary: Compositional-variation-induced CoFe-LDHs fibers with different Co:Fe ratios were prepared using a simple wet-chemical method and electrospinning techniques. The CoFe-LDH0.5 fiber with lower cobalt content showed the highest oxygen evolution reaction (OER) activity. A magnetic study revealed that lower concentration of cobalt ions resulted in higher ferromagnetic interaction and electronic spin polarization in the material.

Boosting of overall water splitting activity by regulating the electron distribution over the active sites of Ce doped NiCo-LDH and atomic level understanding of the catalyst by DFT study

Hariharan N. Dhandapani et al.

Summary: In this study, Ce3+ doping of NiCo-LDH was found to enhance the performance of both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The doping of Ce improved the electronic conductivity of the catalyst and Co-3d states played a dominant role in water splitting activity. This work provides an alternate route to design a highly efficient and cost effective catalyst for global clean energy production.

Encapsulation of ultrafine Pd nanoparticles within the shallow layers of UiO-67 for highly efficient hydrogenation reactions

Zhiming Cui et al.

Summary: A solvent assisted ligand exchange-hydrogen reduction strategy was used to selectively encapsulate ultrafine metal nanoparticles (Pd or Pt) within the shallow layers of MOF UiO-67. By controlling the conditions, the particle sizes of the encapsulated nanoparticles and the thickness of the embedded layers can be easily adjusted. Compact encapsulation of nanoparticles within the shallow layers of MOFs can enhance catalytic efficiency and utilization.

Closed-vessel microwave leaching of valuable metals from spent lithium-ion batteries (LIBs) using dual-function leaching agent: Ascorbic acid

Jenni Lie et al.

Summary: The novel closed-vessel microwave system utilizing ascorbic acid showed efficient leaching of valuable metals from spent LIBs, with leaching efficiency depending on acid concentration, heating rate, and temperature. Optimal conditions for complete leaching were determined as 0.5 M ascorbic acid, 40 degrees C/min heating rate, 10 g/L solid to liquid ratio, and 125 degrees C within 10 min. Although using 0.1 M ascorbic acid could facilitate the reduction of Co (III) to Co (II), additional oxalic acid was required for higher recovery of Co and Mn in the leaching solution.

Synergistic recycling and conversion of spent Li-ion battery leachate into highly efficient oxygen evolution catalysts

Zhijie Chen et al.

Summary: Converting spent Li-ion batteries into efficient energy conversion catalysts through a boriding strategy resulted in high metal ion recovery rates and competitive OER activity. The core@shell structured tri-metal borides@(oxy)hydroxides nanostructures induced by the boriding process were identified as the main reason for the superior OER performance, with fast charge-transfer kinetics and rich catalytic active sites also contributing to the high activity. This strategy has the potential to be applied to recycle and regenerate efficient electroactive materials from other metal-rich wastes for a sustainable energy future.
