Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Effects of Ball Milling on the Structure and Foaming Properties of Soy Protein Isolate

Shipin gongye ke-ji
To enhance the foaming properties of soy protein isolate (SPI), SPI was subjected to ball milling at varying ball-to-material ratios (8:1, 14:1, and 20:1) for 150 min at a rotational speed of 96 r/min, using untreated SPI as a control.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Wet ball milling of zeolite HY

Powder Technology, 2004
Abstract Wet ball milling, as a potential means to decrease the particle size of zeolite HY with minimal loss of crystallinity, was investigated. The diameter of the ball as well as the milling speed and time were varied in the experiments. Particle size distributions of the commercial zeolite HY and the ground samples were obtained to determine the ...

Listening to the Formation of Polymorphs in a Ball Mill

Analytical Chemistry
IIn this contribution, we apply our newly developed ball-milling operando platform, which combines Raman spectroscopy, thermal (IR) imaging, as well as acoustic and high-speed optical video recordings, to the synthesis and transformation of citric acid – isonicotinamide (1 : 2) cocrystal polymorphs in transparent PMMA jars. Particularly, we demonstrate
