Unlocking the Potential of Carbon Nitride (CxNy) Electrocatalysts in Hydrogen Evolution, Oxygen Evolution and Overall Water Splitting

Exploration, EarlyView.
Electrocatalytic water splitting with carbon nitride (CxNy) materials has gained attention due to their synthesis, structure, and robust application. Among various CxNy types, g‐C3N4 is the most stable allotrope and extensively researched. This review explores recent advances in HER, OER, and OWS, focusing on defect engineering, structural engineering,

Psychological Resilience to Climate Change: The Role of Self‐Efficacy, Mindfulness, Perceived Nature Restorativeness, and Subjective Well‐Being

Sustainable Development, EarlyView.
ABSTRACT The current study presents a causal model of climate‐induced psychological resilience by assessing the impact of dispositional mindfulness, self‐efficacy beliefs, and perceived restorativeness of nature. It further examines the associations among climate change coping strategies, subjective well‐being components, eco‐emotions, and resilience ...

Mechanism of the Direct Hydrodenitrogenation of Naphthylamine on Sulfided NiMo/Al2O3 [PDF]

, 2018
The hydrodenitrogenation of 1-naphthylamine was studied over a sulfided NiMo/Al2O3 catalyst between 300 and 350 °C. 1-Naphthylamine reacted to tetralin, naphthalene, 1,2-dihydronaphthalene and 5,6,7,8-tetrahydro-1-naphthylamine. To elucidate the reaction

Processing of spent NiW/Al2O3 catalysts [PDF]

, 2013
Spent oxidized (500 ºC, 5 h) commercial NiW/Al2O3 catalysts were processed using two different routes: a) fusion with NaOH (650 ºC, 1 h), the roasted mass was leached in water; b) leaching with HCl or H2SO4 (70 ºC, 1-3 h). HCl was the best leachant.

Part III: NiMoO4 nanostructures synthesized by the solution combustion method: The influence of material synthesis parameters on the electrocatalytic activity toward the oxygen evolution reaction in an alkaline medium

The Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1238-1250, March 2026.
Schematic of NiMoO4 synthesis and oxygen evolution reaction (OER) performance. Ni/Mo precursor solution with agar is calcined and deposited on a glassy‐carbon electrode, yielding NiMoO4 that catalyzes the OER (H2O → O2). The inset linear sweep voltammetry plot highlights its superior activity compared to IrO2, commercial NiMoO4, and NiO.

Design of Efficient and Mechanically Robust Anion Exchange Membrane for Water Electrolysis Achieved by Chemically Crosslinked Elastomers using Polyfluorene‐Based Conjugated Polymers

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
High‐performance SEBS‐PFB AEM is developed by crosslinking SEBS‐amine with polyfluorene‐based crosslinker containing benzene spacer. With the superior electrochemical and mechanical properties, SEBS‐PFB enabled an AEMWE single cell to achieve a high current density of 14.0 A cm−2 at 2.0 V and 80 °C in 1 m KOH, using a PtRu/C cathode and Ni2Fe anode ...
