Self-standing anatase-TiO2-SiO2 composites bearing multiscale porous architecture demonstrated improved performance in the photodegradation of volatile organic compounds, achieving 80% propan-2-one mineralisation at a Ti/Si molar ratio as low as 0.08-0.15. These properties are related to the materials' unique 'meta-leaf' behaviour, enabling bulk photocatalysis by acting as a 'photonic sponge'.
