Redox flow batteries (RFBs) are known for their exceptional attributes, including remarkable energy efficiency of up to 80%, an extended lifespan, safe operation, low environmental contamination concerns, sustainable recyclability, and easy scalability. One standout characteristics is the separation electrolytes into two distinct tanks, isolating them from electrochemical stack. This unique design allows separate capacity power, offering a significantly higher level adaptability modularity...

Battery grade γ-MnO2 powder was investigated as an oxidant and adsorbent in combination with Fe/Al coagulants for removal of arsenic from contaminated water. Simultaneous oxidation As(III) by coprecipitation/adsorption (one step process) compared pre-oxidation subsequent (two process). The rate MnO2 is completed two stages: rapid initially followed a first order reaction. oxidised to As(V) the release approximately 1:1 molar Mn(II) into solution. No significant pH effect on observed range 4...

Graphitic carbon nitride (g-C3N4) is a promising material for photocatalytic applications. However, it suffers from poor visible-light absorption and high recombination rate of photogenerated electron–hole pairs. Here, Co/La@g-C3N4 with enhanced activity was prepared by co-doping Co La into g-C3N4 via facile one-pot synthesis. displayed better performance, achieving 94% tetracycline (TC) removal within 40 min, as compared (BCN, 65%). It also demonstrated performance in degrading other...

Random copolymers containing both ferrocene groups and thioether were synthesized by free-radical copolymerization of vinylferrocene 2-(methylthio)ethyl methacrylate, the random nature was confirmed spectroscopic studies. Copolymers with ferrocene-to-thioether ratios 8 : 1 1.2 used to modify surfaces gold electrodes, behaviours resulting surface-modified electrodes investigated cyclic voltammetry. The SMEs based on showed superior stability compared poly(vinylferrocene), most stable being...

The electrochemistry of olivine-type iron phosphate (FePO4) as a battery cathode material, in aqueous lithium hydroxide (LiOH), has been investigated. material forms intercalated LiFePO4 reversibly on electroreduction/oxidation. formation Fe3O4 phase, addition to the regeneration FePO4 during reverse oxidation LiFePO4, also occurs. In this regard, mechanism discharge/charge LiOH differs from that non-aqueous solvents.
