Potential technology for seawater electrolysis: Anion-exchange membrane water electrolysis

Fabrication of a hierarchical NiTe@NiFe-LDH core-shell array for high-efficiency alkaline seawater oxidation

“…This limitation has spurred interest in seawater electrolysis as a potential avenue for hydrogen production, leveraging the abundance of seawater resources. 8 , 9 , 10 , 11 , 12 , 13 Yet, the efficiency of seawater electrolysis encounters a challenge. Abundant chlorine ions (Cl − ) in seawater tend to outcompete the oxygen evolution reaction (OER) at the anode for the kinetically swift two-electron chlorine evolution reaction (CER).…”

Decoupled electrolysis for hydrogen production and hydrazine oxidation via high-capacity and stable pre-protonated vanadium hexacyanoferrate

“…Hydrogen (H 2 ) is considered one of the most promising alternatives to traditional fossil fuels due to its zero carbon emissions and high energy density (120 MJ kg −1 ) 1 – 3 . Among various methods for hydrogen production, water electrolysis is a sustainable and environmentally friendly technology that has been receiving lots of attention 4 – 7 . Conventional one step water electrolysis with diaphragm or membrane as the separator typically faces several critical challenges 8 , 9 .…”

Optimized mass transfer in a Pt-based cathode catalyst layer for PEM fuel cells

“…Excessive use of traditional fossil fuels and their detrimental impact on the environment have forced researchers to turn to renewable energy alternatives. 1,2 Addressing future energy and environmental challenges necessitates an unwavering commitment to the ongoing development of sustainable, eco-friendly energy sources. Hydrogen energy stands out as a noteworthy candidate in this endeavour, promising to be an exceptionally high-quality and clean substitute.…”
