Pomegranate peel-derived Cu/hydrochar nanocomposites: a sustainable catalyst for biodiesel production via oleic acid esterification
Transforming pomegranate peel waste into a biodiesel catalyst advances waste-to-resource circularity. A facile hydrothermal carbothermal reduction method was used to synthesize copper-decorated hydrochar nanocomposites derived from peel bio-waste and CuSO4, with Cu(II) concentrations of 10, 25, and 50 mmol/L (denoted a...
