Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

Advanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Active Phase of Nickel Electrocatalysts Driving Alkaline Hydrogen Evolution

Advanced Materials, EarlyView.
Using depth‐resolved and operando spectroscopic measurements coupled with electrochemical mass spectrometry, the authors uncover the critical role of sub‐surface oxidised species in increasing the activity and durability of Ni‐based cathodes for hydrogen evolution.

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

Efficient Hydroxyl Diffusion Triggers Surface Hydronium Enrichment and Bulk Proton Participation to Boost Alkaline Hydrogen‐Evolving Reaction

Advanced Materials, EarlyView.
For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...
