Optimizing NiMo Electrocatalyst Coatings for Hydrogen Evolution in Alkaline Electrolysis With The Machine Learning‐Guided Autonomous Platform CatBot

Advanced Functional Materials, EarlyView.
This work presents a closed‐loop optimization workflow integrating CatBot, an automated synthesis and testing system, to discover NiMo hydrogen‐evolution catalysts. CatBot synthesised and evaluated 228 unique samples, identifying the best performing catalysts for transfer to nickel‐foam electrodes. The best candidate is highly active, reaching 1 Acm−2${

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

Advanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...
