In this research, a tungsten oxide was prepared via green (biogenic) synthesis route where sodium tungstate dihydrate and Punica granatum peel extract were used as precursor reducing/capping agent, respectively. The characterization of the performed through various spectroscopic microscopic techniques. results revealed preparation highly crystalline nanorod-shaped (length = 123 nm width 31.3 nm) with probable chemical formula W5O14. Various functional groups on W5O14 surface also reported. nanorods further for removal Bismarck Brown R (BBR) dye from water in batch manner. By varying dose (0.5–3.0 g L−1), BBR solution pH (2−10), contact time (15–120 min), concentration (10–60 mg temperature (30, 40, 50 °C), optimized condition maximum adsorption efficiency measured. that 2.0 L−1 amount to remove ~98% its 10 at 30 °C 7.0 pH. temperature-dependent data fitted different types non-linear isotherm models (e.g., Langmuir Freundlich) assess potential mechanisms relation impacts. synthesized nano-adsorbent fits well Freundlich model capacity 17.84 g−1. Pseudo-first-order, pseudo-second-order, Elovich kinetic study kinetics. onto follows pseudo-second-order rates. present is governed by physico-chemical predominant interactions.

This study reports the production of a heterojunction copper oxide-zinc oxide nano-photocatalyst based on lemon leaf extract, which acted as both stabilizer and capping reducing agent. The fabricated photocatalyst had smooth surface with numerous functional groups, its energy band gap was measured to be 3.14 eV, is suitable for photocatalytic applications. Toxic Congo Red dye used model pollutant investigate degradation performance proposed CuO-ZnO nano-photocatalyst. exhibited rapid rate under sunlight irradiation, concentration by almost 70 % within 50 min pseudo-first-order kinetics. also evaluated quantum yield figure merit, were found 6.63 x 10−9 molecules photon−1and 3.31 10−4, respectively. In addition, catalyst displayed good stability up 5 cycles. Based these results, outperformed previously reported photocatalysts. mechanisms associated explained an interfacial charge transfer reaction.
