Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide

Advanced Materials, EarlyView.
This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

Advanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Towards Advanced Alkaline Water Electrolysis

Green hydrogen, produced through water electrolysis and renewable electricity, could play a pivotal role in the energy transition. It can serve as a renewable feedstock for the chemical industry, a zero-emission fuel, a substitute for natural gas in heating, and a means of energy storage to bridge gaps between variable electricity supply and continuous

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid

Advanced Materials, EarlyView.
This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional
