Multilayer nanopancakes of LnBO3 (Ln= Sm, Gd) as a novel support for immobilization of laccase


Xinlin Zhou, Qingsheng Wu*, Tiejian Zhu



ABSTRACT: Multilayer nanopancakes of LnBO3 (Ln= Sm, Gd) were obtained without any surfactant or template via a mild Solid-State-Hydrothermal method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) were used to characterize the as-prepared products. The morphology of as-prepared LnBO3 (Ln = Sm, Gd) was characterized by scanning electron microscopy (SEM), which shows that the nanopancakes have typical diameters of 3~5 μm while the thickness of the single layer is range of 10~80 nm. Due to the multilayer structure, the laccase was successfully immobilized on these materials.
