Unveiling the photocatalytic properties of cadmium oxide for sustainable approach towards water remediation: A review

The current state of water resources demonstrates the contamination caused by industrial wastewater draining's supremacy. Because of the serious health and environmental risks caused by the contaminated waterways, a workable solution is needed to address its effect. This review paper presents a comprehensive investigation of the photocatalytic applications of CdO based nanomaterials, including undoped CdO, doped CdO, and CdO coupled with other semiconductors. Through a systematic analysis, we elucidate the diverse characteristics of these nanomaterials, shedding light on their potential applications in various fields. Moreover, this review explores the promising prospects of utilizing CdO-based nanomaterials for environmental remediation, particularly in the photodegradation of textile dyes. Higher the carrier concentration, higher intrinsic mobility, greater transparency of CdO, its tunable band gap and large surface area are its distinguishable characteristics that make it a promising candidate for photocatalytic applications. By leveraging their unique properties, CdO-based nanomaterials offer a sustainable and efficient approach towards addressing environmental challenges associated with textile dye pollution.
