Novel Z-scheme 0D/3D p-Ag6Si2O7/n-Bi2O2CO3 micro-flowers heterojunctions were fabricated by a CTAB-aided deposition and in-situ growth route for the first time. The photocatalysts were characterized systematically via XRD, XPS, SEM, BET, EDS, TEM and Mott-Schottky. Under simulated sunl...
Structural, morphological and crystalline features are analyzed using FESEM, TEM, HRTEM, XRD and XPS studies. Moreover, optical and fluorescence properties of N-GQDs are studied using UV-visible and fluorescence spectroscopic techniques. These studies clearly reveal and confirm the formation of a ...
