Preparation and characterization of Ru-TiO/PC/FeO composite catalyst with enhanced photocatalytic performance and magnetic recoverability under simulated solar light.

This research focuses on the development of a novel Ru-doped TiO/grapefruit peel biochar/FeO (Ru-TiO/PC/FeO) composite catalyst, which exhibits exceptional photocatalytic efficacy under simulated solar light irradiation. The catalyst is highly effective in the degradation of rhodamine B (RhB), methylene blue (MB), methyl orange (MO), as well as actual industrial dye wastewater (IDW), and can be recovered magnetically for multiple reuse cycles. Significantly, the PCTRF-100 sample exhibited degradation efficiencies of 99.

Enhanced photocatalytic activity of porous TiO containing C/P/K derived from grapefruit peel.

Grapefruit peel possesses a porous structure and a significant specific surface area. In this study, we introduce an innovative and eco-friendly approach for synthesizing porous TiO. This was accomplished by employing grapefruit peel as a bio-template and tetrabutyl titanate as the precursor, utilizing a two-step rotary impregnation-calcination process.

Waste Biomass-Mediated Synthesis of TiO/P, K-Containing Grapefruit Peel Biochar Composites with Enhanced Photocatalytic Activity.

In this study, TiO/P, K-containing grapefruit peel biochar (TiO/P, K-PC) composites were synthesized biomimetically using grapefruit peel as the bio-template and carbon source and tetrabutyl titanate as the titanium source. This was achieved using the two-step rotary impregnation-calcination method. Adjusting the calcination temperature of the sample in an air atmosphere could regulate the mass ratio of TiO to carbon.
