Abstract
TiO2 with an enhanced photocatalytic activity was biomineralized using a lysozyme (LYZ)–polystyrene (PS) biotemplate. We present a novel and green biomineralization route for TiO2 particles to increase the photodegradation efficiency of rhodamine B (RhB) under visible light irradiation. The LYZ–PS template was constructed via a facile passive adsorption process under an ambient environment. The electrostatic interaction between PS and LYZ allowed LYZ–PS as a rigid template to function as a nucleation core to induce the biomineralization of TiO2 particles. The LYZ–PS template not only enabled the empty structure in the particles during calcination but also provided a higher nitrogen content in the final TiO2 photocatalyst. The LYZ–PS templated TiO2 exhibited improved photocatalytic activity with au. 98% degradation of RhB after 80 min under solar light irradiation. The enhanced photocatalytic performance can be attributed to the synergetic effect of morphology, crystallinity and band gap.
