Effective Catalytic Esterification of Fat-Oil-Grease into Biodiesel over Sulfonated Zinc-Carbon Catalysts

This study demonstrates that a sulfonated zinc-carbon catalyst (ACZnS-220-5wt%), synthesized from sunflower husk via hydrothermal treatment and sulfonation, effectively converts waste fat-oil-grease into biodiesel with an 88% yield and stable reusability over five cycles due to its high surface area and strong Zn-S acid sites.
