Photocatalytic Hydrogen Production using Porous 3D Graphene-Based Aerogels Supporting Pt/TiO₂ Nanoparticles.

ABSTRACT: Composites involving reduced graphene oxide (rGO) aerogels supporting Pt/TiO₂ nanoparticles were fabricated using a one-pot supercritical CO₂ gelling and drying method, followed by mild reduction under a N₂ atmosphere. Electron microscopy images and N₂ adsorption/desorption isotherms indicate the formation of 3D monolithic aerogels with a meso/macroporous morphology. A comprehensive evaluation of the synthesized photocatalyst was carried out with a focus on the target application: the photocatalytic production of H₂ from methanol in aqueous media. The reaction conditions (water/methanol ratio, catalyst concentration), together with the aerogel composition (Pt/TiO₂/rGO ratio) and architecture (size of the aerogel pieces), wer
