A facile oxygen vacancy and bandgap control of Bi(OH)SO4·H2O for achieving enhanced photocatalytic remediation

Synergistic enhancement of seawater hydrogen generation via sulfur vacancy enriched and phases engineered CQD loaded CdS photocatalyst

“…The PVP@CdS possesses the smaller band gap of whereas the N-CQD@CdS and CQD@CdS have wide band gaps. The presence of CQD did not have a significant change in optical properties 73 and this was also confirmed from other results reported in the literature that showed similar results to ours. 65,74 The average particle size (R) of the CdS nanoparticles was estimated using the Brus eqn ( 7):…”
