Photovoltaic-driven stable electrosynthesis of HO in simulated seawater and its disinfection application.

Electrosynthesis of HO through O reduction in seawater provides bright sight on the HO industry, which is a prospective alternative to the intensively constructed anthraquinone process. In this work, a photovoltaic-driven flow cell system is built for the electrosynthesis of HO in simulated seawater using N-doped carbon catalysts. The N-doped carbon catalysts with multiple N-doped carbon defects can achieve a record-high HO production rate of 34.

Electrochemical Reactors for Continuous Decentralized H O Production.

The global utilization of H O is currently around 4 million tons per year and is expected to continue to increase in the future. H O is mainly produced by the anthraquinone process, which involves multiple steps in terms of alkylanthraquinone hydrogenation/oxidation in organic solvents and liquid-liquid extraction of H O . The energy-intensive and environmentally unfriendly anthraquinone process does not meet the requirements of sustainable and low-carbon development.

Overcoming Acidic HO/Fe(II/III) Redox-Induced Low HO Utilization Efficiency by Carbon Quantum Dots Fenton-like Catalysis.

Fenton reaction has important implications in biology- and environment-related remediation. Hydroxyl radicals (OH) and hydroxide (OH) were formed by a reaction between Fe(II) and hydrogen peroxide (HO). The acidic HO/Fe(II/III) redox-induced low HO utilization efficiency is the bottleneck of Fenton reaction.

High temperature proton exchange membrane fuel cells: progress in advanced materials and key technologies.

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are one type of promising energy device with the advantages of fast reaction kinetics (high energy efficiency), high tolerance to fuel/air impurities, simple plate design, and better heat and water management. They have been expected to be the next generation of PEMFCs specifically for application in hydrogen-fueled automobile vehicles and combined heat and power (CHP) systems. However, their high-cost and low durability interposed by the insufficient performance of key materials such as electrocatalysts and membranes at high temperature operation are still the challenges hindering the technology's practical applications.
