Preparation and Characterization of Bimetallic Nanocatalyst Supported on Activated Carbon Prepared from Papaya Seeds

Received: 15 January 2026;  Published: 16 June 2026;  doi: 10.21926/cr.2602006

Abstract

Preparation and characterization of an iron-tin bimetallic nanocatalyst supported on activated carbon (AC) prepared from papaya seeds, which was previously available in the surrounding environment, were performed. Different characterization techniques such as scanning electron microscopy (SEM), FT-IR spectrometry, and UV-Vis spectrophotometry were used. Many properties were characterized, and the resulting activated carbon could serve as an inexpensive catalytic support with a high surface area [...]

Rapid Degradation of Tartrazine Yellow Dye by Photo-Fenton Action at the Interface of Magnetite and Silica Nanoparticles

Received: 14 February 2026;  Published: 07 June 2026;  doi: 10.21926/cr.2602005

Abstract

This study reports the synthesis of magnetic nanoparticles (Fe3O4) supported on silica (SiO2), obtained from the chemical and thermal treatment of coconut mesocarp. The spectroscopic and morphological properties of this nanocomposite composed of magnetite and silica (Np-Fe3O4/SiO2) were investigated using Infrared (FTIR), Ultraviolet and Visible (UV-Vis), X-ra [...]
