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 ...

Efficiency of Fenton Oxidation in Reducing High Concentrations of Humic Acid in Aqueous Solutions [PDF]

آب و فاضلاب, 2015
Advanced oxidation processes produce hyperactive hydroxyl radicals that have a high potential for the oxidation of organic compounds. One of these processes is the Fenton process in which iron ion as a catalyst reacts with oxidants in an acid environment

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Direct oxidation of organic micropollutants by persulfate and hydrogen peroxide: A potentially misleading contribution in advanced oxidation processes

Chemical Engineering Journal Advances
Advanced oxidation processes (AOPs) are becoming increasingly attractive for the removal of organic micropollutants (OMPs) from water. However, various aspects of AOPs need to be carefully evaluated. Most AOPs involve the introduction of oxidants such as

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...
