A New Life for Tionite Industrial Waste: Regeneration Strategy towards Photocatalytic Applications.

ABSTRACT: Industrial waste management is an urgent problem to solve possibly by recycling, reuse and recovery of resources. In this framework, the sludge of the TiO₂ manufacturing, called tionite, is of certain interest because it contains metallic oxide-bearing impurities, dangerous to the environment. Hence, we propose a strategy to recover TiO₂ from tionite, towards its effective re-use as a photocatalyst. In detail, tionite was treated under acidic or alkaline conditions to remove impurities and improve the TiO₂ accessibility, and each single purification step was monitored by a thorough multi-technique characterization. The photocatalytic activity of the modified tionite materials was tested for the partial oxidation of ferulic acid to vanillin, a relevant susta
