Cathode Upcycling for Direct Recycling of Lithium‐Ion Batteries Using a Precipitation Approach
To improve the circularity of lithium‐ion batteries, researchers develop a low‐cost method to increase the energy density of directly recycled cathodes. Through a precipitation process, low‐nickel materials are converted to high‐nickel compositions. Using synchrotron 3D X‐ray imaging and diffraction, they track nickel diffusion during high‐temperature ...

Al‐Doped LaTiO2N Prepared via Flame Spray Pyrolysis for Photocatalytic Hydrogen Evolution
Flame spray pyrolysis enables the synthesis of La–Ti oxides with a simple perovskite‐type structure, and Al doping promotes the formation of the simple perovskite‐type La–Ti oxides. The Al‐doped LaTiO2N obtained by nitridation has a reduced defect concentration due to suppressed structural change, which contributes to the improvement of hydrogen ...

Improvement of Catalytic Methane Oxidation by Nitric Acid Treatment on Pt/TiO2
This study investigates the impact of nitric acid (NA) treatment on Pt/TiO2 catalysts for methane oxidation. Optimizing the NA concentration enhances Pt dispersion and catalytic performance by facilitating the formation of surface acidic sites. However, excessive treatment results in Pt particle aggregation and diminished activity. These findings offer

A scalable method is presented to manufacture high‐capacity Si electrodes for Li‐ion batteries where skeletal porous Ti(Al,Si)2@Si particles are synthesized by gas atomization and acid etching. The fine pores have a buffering effect that suppresses volume expansion during lithiation, and the high electrical conductivity of the particles greatly ...
