“…RhB has been used in many studies to evaluate the activity of photocatalyst [30][31][32][33][34], while the general test concentration of RhB is about 10 À 5 mol/L. To the best of our knowledge, the photocatalytic activity and adsorbability of Si-GO/BWO nanoplates for degradation of concentrated RhB (6.0 Â 10 À 5 mol/L) in different experimental conditions are being researched for the first time.…”

Herein, for the first time, a direct Z-scheme g-C 3 N 4 /NiFe 2 O 4 nanocomposite photocatalyst was prepared using facile one-pot hydrothermal method and characterized using XRD, FT-IR, DRS, PL, SEM, EDS, TEM, HRTEM, XPS, BET and VSM characterized techniques. The result reveals that the NiFe 2 O 4 nanoparticles are loaded on the g-C 3 N 4 sheets successfully. The photocatalytic activities of the as-prepared photocatalysts were evaluated for the degradation of methyl orange (MO) under visible light irradiation. It was shown that the photocatalytic activity of the g-C 3 N 4 /NiFe 2 O 4 nanocomposite is about 4.4 and 3 times higher than those of the pristine NiFe 2 O 4 and g-C 3 N 4 respectively. The enhanced photocatalytic activity could be ascribed to the formation of g-C 3 N 4 /NiFe 2 O 4 direct Z-scheme photocatalyst, which results in efficient space separation of photogenerated charge carriers. More importantly, the as-prepared Z-scheme photocatalyst can be recoverable easily from the solution by an external magnetic field and it shows almost the same activity for three consecutive cycles. Considering the simplicity of preparation method, this work will provide new insights into the design of high-performance magnetic Z-scheme photocatalysts for organic contaminate removal.

“…Various approaches have been attempted to overcome the problem of carrier recombination, such as doping 7 , porous films 8 , and bilayer structures 9 . In particular, the use of heterojunction structures can promote the separation of electrons and holes and the absorption of photons, while further reducing the width of the bandgap.…”

In 2 O 3 micro-cubes were fabricated via chemical bath deposition (CDB) on an indium tin oxide (ITO) substrate, over which highly textured Bi 2 WO 6 nanopillars were grown via a diffusion-and-aggregation phenomenon by electrostatic spraying deposition (ESD). The resulting heterojunction bilayer exhibited a photocurrent density value of 1.03 mA/cm 2 under visible light of 100 mW/cm 2 intensity. Widening the light absorptivity spectrum and reducing the charge recombination enhanced the performance of the heterojunction bilayer films for solar water splitting.
