Printed Liquid Metal-Solid Metal Hybrid Electrodes for Stabilizing Liquid Platinum-Gallium Droplets During Electrocatalysis. [PDF]
SmallA printed liquid‐metal catalyst platform is developed by confining Pt‐in–Ga liquid metal droplets within a tungsten nanoparticle matrix on porous Mo substrates. This architecture suppresses liquid metal droplet agglomeration and leaching, enabling durable and highly active electrocatalysis for both HER and CO2RR, with Pt‐dependent active motifs ...

Multimetal Doping and Heterostructure Engineering of RuO<sub>2</sub> for Durable and Efficient Oxygen Evolution. [PDF]
Small SciA MnCoNi–RuO2 heterostructure engineered through multimetal doping and mixed‐oxide interface formation generates lattice distortion, oxygen vacancies, and electronically optimized active sites for the oxygen evolution reaction. MnCoNi–RuO2 achieves high activity and durability across alkaline and acidic media, sustaining 100 h (AEMWE) anion exchange ...

Pt NPs Supported on CeO<sub>2</sub>/C as Electrocatalysts for Oxygen Reduction Reaction: Novel Physicochemical Insights on the Synthesis and on the Improved Activity and Stability. [PDF]
SmallThe effect of CeO2 on the Pt nanoparticles nucleation and growth and on the activity versus the oxygen reduction reaction was studied by in situ synchrotron wide‐angle X‐ray total scattering. The most active catalyst (MA = 423 A g−1; SA = 446 µA cm−2) shows greater stability than the commercial benchmark as demonstrated by accelerated stress tests at ...

Evaluation of Alternative Lithium Salts for High-Voltage Lithium Ion Batteries: Higher Relevance of Plated Li Morphology Than the Amount of Electrode Crosstalk. [PDF]
SmallHigh voltage (>4.5 V) LiNixCoyMnzO2 (NCM)||graphite cells show rollover failure in the course of electrode crosstalk, i.e., transition metal (TM) dissolution from NCM and deposition on graphite. Interestingly, oxidatively less stable Li salts enhance the cycle life despite higher electrode crosstalk, as the morphology of plated Li has a lower surface ...

Liquid Metal Electrocatalyst with Ultralow Pt Loading for Ethanol Oxidation. [PDF]
Small SciHerein, Pt–Ga liquid metal electrocatalyst has demonstrated a remarkably high mass activity towards ethanol oxidation. A low‐concentration alkaline electrolyte is formulated with guidance of machine learning neural networks. Theoretical calculation reveals that the enhanced reactivity of Pt atoms is attributed to the presence of liquid metal Ga and the
