“…Subsequently, the low‐temperature electron paramagnetic resonance (EPR) technique was employed to explore the process of electron transfer from ligand to central coordinated Zn 2+ . A peak assigned to V 4+ (3d 1 ) was detected on BVNS in dark (Supporting Information, Figure S21a), supporting the XPS results. The typical EPR signals of ZnPc centering at g =1.9998 and 1.9684 (Supporting Information, Figure S21b), resulting from the dissociative free electrons in the ZnPc ligand and the partially reduced Zn + , are observed, respectively .…”

“…It is clear that there is an optimized light intensity for exciting BVNS and ZnPc,further declaring the importance of light absorption matching between these two constituents in Z-scheme system. Subsequently,the low-temperature electron paramagnetic resonance (EPR) technique was employed to explore the process of electron transfer from ligand to central coordinated Zn 2+ .Apeak assigned to V 4+ (3d 1 )w as detected on BVNS in dark (Supporting Information, Figure S21a), [27] supporting the XPS results.T he typical EPR signals of ZnPc centering at g = 1.9998 and 1.9684 (Supporting Information, Figure S21b), resulting from the dissociative free electrons in the ZnPc ligand and the partially reduced Zn + , are observed, respectively. [28] Interestingly,there is no detectable change of EPR signals under 520 or 660 nm excitation (Supporting Information, Figure S22a,b).…”

“…ForZ nPc, it evenly increases from 700 to 600 nm, consistent with its specific absorption. Subsequently,the low-temperature electron paramagnetic resonance (EPR) technique was employed to explore the process of electron transfer from ligand to central coordinated Zn 2+ .Apeak assigned to V 4+ (3d 1 )w as detected on BVNS in dark (Supporting Information, Figure S21a), [27] supporting the XPS results.T he typical EPR signals of ZnPc centering at g = 1.9998 and 1.9684 (Supporting Information, Figure S21b), resulting from the dissociative free electrons in the ZnPc ligand and the partially reduced Zn + , are observed, respectively. However,w hen 660 nm monochromatic light is assisted to excite ZnPc,t he photocurrent density of 1ZnPc/BVNS sharply increases from 520 to 400 nm.…”

“…In this contribution, we report for the first time a physical route technique i. e. high energy ball milling (HEM) for the synthesis of Ag‐BiVO 4 nanocomposites along with its physico‐chemical features and photochemical reactivity . Exhaustive analyses were performed by HR‐TEM and FE‐SEM to probe the structure, morphology and organization of the nanocomposites.…”

“…[18] In this contribution, we report for the first time a physical route technique i. e. high energy ball milling (HEM) for the synthesis of Ag-BiVO 4 nanocomposites along with its physicochemical features and photochemical reactivity. [19] Exhaustive analyses were performed by HR-TEM and FE-SEM to probe the structure, morphology and organization of the nanocomposites. From the dielectric measurements, electrical conductivity and polarization effects were determined and correlate with the density of metal-semiconductor interfaces involved at nano-scale between metallic clusters and BiVO 4 nanoparticles.…”
