Rational structural design of graphene oxide/W18O49 nanocomposites realizes highly efficient removal of tetracycline in water

Dual-defected pine-needle W18O49–TiO2(R)–TiO2(A) heterojunctions for the complete elimination of naphthalene

“…The highest surface area of 113.9 m 2 g À1 for WTNWs-2 would be obtained, which may be owing to the surface defects based on the XRD patterns, resulting in a significant improvement in the organic pollutants' adsorption capacity. 47 The molar percentage of TiO 2 (R) obtained by the empirical formula further proved the crystal microstructure distortion owing to the surface defects. 48 The actual molar ratio of tungsten to titanium species in the WTNWs samples can be reached with about 80.0% feed ratio, further proving the successful incorporation of tungsten species.…”
