Efficient algal lipid extraction via a green bio-electro-Fenton process and its conversion into biofuel and bioelectricity with concurrent wastewater treatment in a photosynthetic microbial fuel cell

Abstract

Third-generation biodiesel produced using carbon-neutral algal feedstock is a promising alternative to meet global energy demands. However, the economic viability of algae-derived biodiesel is severely impacted by poor lipid recovery...

Enhancing catalyst stability: Immobilization of Cu–Fe catalyst in sodium alginate matrix for methyl orange removal via Fenton-like reaction

“…Despite its advantages, the Fenton reaction is hindered by high acidity requirements (pH ∼3), iron sludge formation, and metal leaching, which pose sustainability and environmental challenges in water treatment processes [ 13 ]. Numerous researchers have explored heterogeneous catalysts to overcome these drawbacks, aiming for reaction reusability [ 14 , 15 ]. However, these catalysts still operate under acid conditions, presenting a persistent challenge in achieving a more sustainable and environmentally friendly water treatment approach [ 16 , 17 ].…”
