Optimization of Biodiesel Production from Waste Cooking Oil over a Magnetic Fe–Zr Nanocatalyst
The increasing demand for sustainable and low-cost biodiesel production has driven interest in waste cooking oil (WCO) as an alternative feedstock. In this study, a mesoporous magnetic Fe–Zr nanocatalyst with a specific surface area of 203.12 m²/g was synthesized via co-precipitation followed by incipient wetness impre...
