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

open access: yesAdvanced 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 ...

Lanthanum‐Induced Gradient Fields in Asymmetric Heterointerface Catalysts for Enhanced Oxygen Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
Uncontrolled atomic migration during the pyrolysis of metal‐N‐C catalysts often leads to disordered coordination environments, active site loss, and poor oxygen electrocatalytic activities. Herein, a La‐mediated atomic migration strategy enables the fabrication of a well‐defined asymmetric heterostructure (LaN/LaFe‐NC) featuring a built‐in electric ...

Polystyrene Nanoplastic‐Mercury Complexes Detection by Electrolyte‐Gated Carbon Nanotube Field‐Effect Transistor‐Based Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
An electrolyte‐gated field effect transistor sensor is used to detect an environmentally relevant nanoplastic model. The sensor identifies the presence of polystyrene nanoplastics in water dispersions without significantly altering its performance in the presence of mercury on the nanoplastics’ surface, indicating that it may be utilized in ...

Deciphering the Interactions of Carbon Nanotubes and Super P with Silicon and Graphite Active Materials in Silicon‐Graphite Negative Electrode‐Based Lithium‐Ion Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Although defect‐rich Multi‐walled Carbon Nanotubes (MWCNTs) are generally associated with reduced electronic conductivity, our findings uncover a different role: they act as interfacial mediators in Silicon (Si) negative electrode‐based lithium‐ion batteries. Their defect sites and surface functional groups reinforce particle contact, markedly boosting

Nitrogen‐Doped Amorphous Carbon Film for Enhanced Cu2+ Electrochemical Sensing in Marine Environments

open access: yesAdvanced Materials Interfaces, EarlyView.
Large‐area N‐doped amorphous carbon films are synthesized at room temperature via hybrid linear ion source technique. Nitrogen doping promotes the formation of sp2−C and C‐N bonds, thus enhancing the electrode's sensitivity. These electrodes achieve ultra‐low Cu2+ detection (8 × 10−3 mM) in 3.5 wt% NaCl and exhibit excellent stability/repeatability for
