Unleashing the Power of P‐N Heterojunctions: Optimizing Water Electrolysis Efficiency Through a Cathode‐Driven Electrocatalyst Synergy

Advanced Science, EarlyView.
This groundbreaking contribution to water electrolysis demonstrates that MoSe2/PANI electrocatalysts with a P–N heterojunction effectively balance the overall electrolysis reaction as the cathode, enhance anode performance, and achieve high‐efficiency, low‐energy, simultaneous hydrogen and oxygen production, revealing that the P–N heterojunction ...

Electrocatalysis of free chlorine on hydrogen oxidation

Electrochemistry Communications
A novel view of the electrocatalysis of free chlorine on hydrogen oxidation was proposed by cyclic voltammetry (CV) in seawater solutions. Since seawater has good pH buffering from its composition (bicarbonate, carbonate, borate, etc.), there is no need ...

Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

Advanced Science, EarlyView.
By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.

Electrooxidation of a cobalt based steel in LiOH: a non-noble metal based electro-catalyst suitable for durable water-splitting in an acidic milieu

, 2017
The use of proton exchange membrane (PEM) electrolyzers is the method of choice for the conversion of solar energy when frequently occurring changes of the current load are an issue. However, this technique requires electrolytes with low pH.
