Design and Preparation of Carbon Nitride Based Amphiphilic Janus N-Doped Carbon/MoS2 Nanosheets for Interfacial Enzyme Nanoreactor

The Janus amphiphilic particles have gained much attention for their important application value in areas as diverse asinterfacial modification, sensors, drug delivery, optics and actuators. In this work, we prepared Janus amphiphilic nanosheets composed of nitrogen doped stratiform meso-macroporous carbons (NMC) and molybdenum sulfide (MoS2) for hydrophilic and hydrophobic side, respectively. The dicyandiamide and glucose were used as precursors for synthesizing two-dimensional nitrogen doped meso-macroporous carbons and the molybdate could be anchored by the functional groups, on the surface of carbon layers, then transform into uniformly MoS2 to form the Janus amphiphilic layer by layer NMC/MoS2 support. Transmission electron microscope (TEM)，Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy, are used to demonstrate the successful preparation of Janus materials. As typical interfacial enzyme, Candida Rugosa lipase (CRL) immobil...
