ZnO@SiO₂-TTIP was synthesised as a novel heterogeneous catalyst and characterised by FT-IR, XRD, TEM, SEM and N₂ adsorption-desorption. In this catalytic system, TTIP acts as a dopant agent for ZnO@SiO₂ to decreases the recombination of photogenerated electron/hole pairs and improves the catalyst activity. The catalyst was successfully utilised for the synthesis of 2-substituted benzimidazoles and benzothiazoles from 1,2-phenylenediamine and 2-aminothiophenol with wide variety of aromatic aldehydes.

核/壳结构ZnO @ SiO ₂ -TTIP复合纳米粒子作为合成2-取代苯并咪唑和苯并噻唑的有效催化剂

合成了一种新型的多相催化剂ZnO @ SiO ₂ -TTIP，并通过FT-IR，XRD，TEM，SEM和N ₂吸附-脱附表征。在该催化体系中，TTIP充当ZnO @ SiO ₂的掺杂剂，以减少光生电子/空穴对的重组并提高催化剂活性。该催化剂已成功地用于由1,2-苯二胺和2-氨基苯硫酚与多种芳香族醛合成2-取代的苯并咪唑和苯并噻唑。
