Sodium Borohydride‐Assisted Catalytic Property of BiOCl Nanoparticles for Water Remediation

The fundamental metal oxyhalides’ chemical catalytic property in converting 4‐nitrophenol to 4‐aminophenol is observed. The degradation efficiency for the most effective sample is about 100%, and the rate kinetics is 1.88 min⁻¹ within a 4‐min interval. The transformation is performed at ambient temperature and in the aqueous sodium borohydride solution. This study reports an easy, cost‐effective, and eco‐friendly hydrothermal synthesis of bismuth oxychloride (BiOCl) nanomaterials. In addition to the synthesis assertions, various sophisticated techniques are being used to investigate nanomaterials’ optical and electronic properties. The tunability of band formation and phase equilibrium of nanomaterials and the relationship between nanomaterials and catalytic activity are examined. The synthesized nanomaterials are very valuable for wastewater remediation in the aquatic environment.
