Biotemplating is an effective strategy to obtain morphology controllable materials with structural specialty, complexity, and related unique properties. Due to the presence of nanocavities and channels, the biotemplated materials possess hierarchical pore network and complex functional patterns, as well as biogenic doped chemical elements, which might be particularly suitable for catalysis and separation. In this presentation, we used plant skins, tobacco, natural rubber latex, reed leaves and hydrilla as templates to fabricate mesoporous titania and ZnIn₂S₄. These biotemplated catalysts have good photocatalytic activity which could be used for photocatalytic degradation of organic pollutants, photocatalytic H₂ evolution and photocatalytic reduction of Cr⁶⁺, oxidation of As³⁺.
