Stock solutions in deuterated water of PTAS (300 µM), CuBr2 (100 µM) and Pb(NO3)2 were prepared. Samples were obtained through mixing the probe and analyte solutions with different ratios and bringing them to a final volume of 1 ml. Acquisition parameters for the 1H-NMR experiments:...
The TEM image of bulk g-C3N4 exhibited many enfolded and wrinkled thin sheets; on the other hand, the pure MgSiNS sample showed the presence of relatively thick (15 nm) sheets, revealing the successful synthesis of MgSiNS and g- C3N4 with sheet morphology. The TEM images of MgSiNS-GN5...
