HNb3O8/g-C3N4 nanosheet composite membranes with two …
2022年8月15日 · The channel sizes inferred from the MWCO values were larger than the interlayer spacing determined by XRD for the HNb 3 O 8 /g-C 3 N 4 composite membranes. These results suggest that the void structure (as in the HNb 3 O 8 membrane) also serves as a permeation channel for the HNb 3 O 8 /g-C 3 N 4 composite membrane.
