“…Naing et al. studied the photocatalytic performance of Bi/BiOCl/MMT synthesized by the simple hydrothermal method (Naing et al., 2022). Their photocatalytic activity was checked by the degradation of RhB and the maximum degradation rate attained was 99% when the initial concentration of RhB was 20 mg/L in 30 min, which was higher than that of Bi/BiOCl.…”

Organic dye pollutants are the most common type of pollutant found in water and wastewater as a result of various industrial activities. In particular, one of the largest contributors is the textile industry, which uses a lot of organic dyes to produce its goods. Organic dyes that remain in the effluents are typically permanent and difficult to detoxify using traditional wastewater treatment strategies. Photocatalysis using semiconductors have emerged as an attractive wastewater treatment method for resolving the major drawbacks of traditional methods. Montmorillonite has been presented as a conceivable dye adsorbent. When a semiconductor is incorporated, its adsorptive capability assists in imposing heterogeneous photoactivity. It is widely employed in a variety of applications due to fundamental characteristics such as high flexibility, swelling, ion exchange ability, acidity, usage in catalytic amounts, milder reaction conditions, benefit in reusability, selectivity, high yield, cheap cost, and so on. In this review, we specifically describe the last 3 years' development of dye degradation employing recently developed montmorillonite (MMT)‐based materials, as well as their preparation methods. In addition, the photocatalytic degradation of various types of organic dye pollutants, such as anionic and cationic dyes, was also studied in this review. The findings reveal that MMT‐based materials have a wide range of applications in the photocatalytic degradation of contaminants existing in the environment.

Recent Clay-Based Photocatalysts for Wastewater Treatment

et al. 2023

Photocatalysis is a remarkable methodology that is popular and applied in different interdisciplinary research areas such as the degradation of hazardous organic contaminants in wastewater. In recent years, clay-based photocatalyst composites have attracted significant attention in the field of photocatalysis owing to their abundance, excellent light response ability, and stability. This review describes the combination of clay with focusing photocatalysts such as TiO2, g-C3N4, and Bi-based compounds for degrading organic pollutants in wastewater. Clay-based composites have more active surface sites, resulting in inhibited photocatalyst particle agglomeration. Moreover, clay enhances the creation of active radicals for organic pollutant degradation by separating photogenerated electrons and holes. Thus, the functions of clay in clay-based photocatalysts are not only to act as a template to inhibit the agglomeration of the main photocatalysts but also to suppress charge recombination, which may lengthen the electron–hole pair’s lifespan and boost degrading activity. Moreover, several types of clay-based photocatalysts, such as the clay type and main photocatalyst, were compared to understand the function of clay and the interaction of clay with the main photocatalyst. Thus, this study summarizes the recent clay-based photocatalysts for wastewater remediation and concludes that clay-based photocatalysts have considerable potential for low-cost, solar-powered environmental treatment.

“…[15][16][17] For example, Mt as a carrier for photocatalysts could significantly improve the adsorption capacity of pollutants. 18,19 However, our previous study found excellent photocatalytic properties of kaolinite due to the isomorphic substitution of Fe atoms in natural iron-rich clay minerals, degrading 80% of RhB within 120 minutes, and systematically analyzed the differences in the photocatalytic properties of Al-O and Si-O sublayers. 20 Mt was composed of three-layer structural units, wherein each unit comprised two Si-O tetrahedral layers and one Al-O octahedral layer, and similar to kaolinite, the Si and Al atoms in the sublayers were isomorphically substituted by Fe atoms.…”
