Valorizing Banana Peel Waste into Mesoporous Biogenic Nanosilica and Novel Nano-biofertilizer Formulation Thereof via Nano-biopriming Inspired Tripartite Interaction Studies.

ABSTRACT: The present study attempts to valorize banana peel waste (BPW) into high-value precipitated nanosilica-based agri-input. XRD analysis revealed smaller-sized biogenic nanosilica (BNS) with an increase (without heating) or decrease (with heating) in the duration of acid pretreatment during the pre-calcination step. The highest BNS yield was recorded in post-calcinated BPW ash involving simultaneous acid and heat treatment (1 h) (SA-3). FTIR analysis displayed an intense peak at 1078.3 cm^-1, indicating "Si-O-Si bond" asymmetric vibrations. FESEM-EDX micrographs revealed high-purity BNS of predominantly spheroid morphology. The BJH plot exhibited mesoporous nanosilica with a median pore diameter of ∼33.82 nm. The bipartite interaction of 0.001 g mL^-1 BNS signifies growth-
