Abstract Biodiesel, an important sustainable fuel used in the transportation sector, demands a stable, recyclable and green catalyst for its economical environmentally benign production. A novel heterogeneous acid was developed by extracting sodium silicate from bamboo leaf ash (BLA), using which SBA-16 (BLA) synthesized then impregnated with 10 wt% each of WO 3 ZrO 2 , characterized evaluated transesterification Ankol seed oil methanol to biodiesel. XRD, SEM, TEM pore size characterization indicated that were present outside mesopores as monoclinic phases, thus 3D cubic cage-like Im3m unaltered. NH -TPD presence sites two distinct strengths, attributed Lewis Brønsted acidity –ZrO into hence gave highest biodiesel yield 98 %. In contrast separately 65 57 % respectively, possibly due alone them. Among (10 %)–ZrO %) mesoporous supports viz. (synthesized tetraethyl orthosilicate), SBA-15, MCM-41, MCM-48, KIT-6, FDU-5, TUD-1, given spherical morphology strong interaction inferred SEM XPS characterizations respectively. From effect process parameters on %)/SBA-16 catalyst, maximum obtained at temperature °C, amount 200 mg, methanol:oil weight ratio 10:1 reaction time h. Under these conditions, it retained same six recycles after regeneration every time, confirmed catalytic stability recyclability.
