Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.

One‐Step Synthesis of Size‐Controlled Copper Oxide Nanoparticles on Laser‐Induced Graphene Sensor for L‐Cysteine Detection

Advanced Electronic Materials, EarlyView.
Oxygen plasma treatment enhances polyimide hydrophilicity and promotes uniform anchoring of copper ion precursors. A one‐step laser process then generates CuO‐decorated nanoparticles on laser‐induced graphene (LIG) electrodes, enabling controlled nanoparticle growth via precursor concentration tuning.
