Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

General Synthesis of Amorphous Pd‐Based Nanoparticles Towards Highly Efficient Nitrate‐to‐Ammonia Electrocatalysis

Advanced Functional Materials, EarlyView.
A family of amorphous palladium‐based multi‐component phosphides nanoparticles, synthesized via a robust one‐step wet‐chemical method, overcoming the immiscibility of different elements and the difficulty in forming a stable, disordered structure. When applied in the electrochemical nitrate reduction reaction, these nanocatalysts effectively suppress ...

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.
