Abstract

Abstract:
This study aims to develop and characterize catalytic materials based on titanium dioxide TiO2, either in pure form or supported on Algerian diatomite. The prepared materials were investigated for their structural, textural, and optical properties using various physico-chemical techniques.Their photocatalytic performance was evaluated in hydrogen production under visible light and in the degradation of organic pollutants such as methylene blue.
The results revealed that the 0.7Ti sample exhibited the highest photocatalytic activity, with a hydrogen production rate of 230 μmol/h, attributed to the formation of a rutile/brookite heterojunction. Meanwhile, the diatomite-supported 35TD sample showed good performance with a rate of 180 μmol/h, and methylene blue degradation exceeded 93.3% within 120 minutes. These findings open promising perspectives for clean energy generation and wastewater treatment applications.
Keywords: H2 production • Heterophase junction • TiO2 • Visible light
