“…For example, the authors' research group reported the use of OPL to produce silica-containing materials, which were then used as precursors in the manufacture of calcium silicate derivatives (Yudha et al, 2020a), ZnO-SiO2, and Zn2SiO4 (Yudha et al, 2020b). Moreover, the decomposition product of OPL was used as a support material for gold particles as catalysts for the reduction of nitroarene compounds (Yudha et al, 2021).…”

Oil palm leaves are natural sources of bio-silica. In situ carbothermal degradation was conducted at 600°C using silver nitrate as a metallic silver (Ag) precursor and oil palm leaves as a silica (SiO2) source. X-ray diffraction of the solid product (Ag@OPLA600) revealed the presence of Ag and SiO2 from the oil palm leaves. Fourier transform infrared spectroscopy showed an absorbance consistent with the presence of SiO2. Scanning electron microscopy revealed a solid surface with cavities. Ag@OPLA600 was used as a heterogeneous mediator to reduce p-nitrophenol to p-aminophenol within 15 minutes. This work provides a new approach for the utilization of sustainable natural resources as a metal Ag supporting material to produce a mediator for the conversion of p-nitrophenol to p-aminophenol in a simple manner.
