Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

open access: yesAdvanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.

High‐Yield Synthesis of Fe‐NC Electrocatalysts Using Mg2+ Templating and Schiff‐Base Porous Organic Polymers

open access: yesAdvanced Functional Materials, EarlyView.
Fe─NC porous oxygen reduction electrocatalysts are prepared employing a 2,4,6‐Triaminopyrimidine‐based porous organic polymer, a Mg2+ Lewis acid, and a low‐temperature cation exchange protocol. Using the polymer precursor achieves high pyrolysis yields and results in atomically dispersed FeNx sites. The resulting catalysts feature hierarchical porosity

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

open access: yesAdvanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

Advances in Stimuli‐Responsive Organic Materials and Polymers toward Intelligent CO2 Capture

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of the relationship between different stimuli and stimuli‐responsive organic materials and polymers for carbon dioxide (CO2) capture. Main stimuli include redox, pH, magnetism, temperature, light, and pressure. Furthermore, multi‐responsive materials, due to their high adaptability and scalability in complex environments, are ...

Self‐Reconstruction of Dual‐Morphology Copper‐Iron Selenides for Cost‐Effective Oxygen Evolution Toward Industrial Alkaline Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
Departing from conventional Ni/Co‐based catalysts, this work presents a Ni/Co‐free CuFe–Se/CFF electrocatalyst with nanoblock–nanorod morphology. It delivers 1000 mA cm−2 at 330 mV overpotential and 620 h stability for the oxygen evolution reaction (OER).

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...
