“…Dye is among the critical industrial anionic direct extensively used in production that has been determined to pose health-confirmed hazards. One of the toxic anionic azo dyes, Congo Red (CR), due to its stable structure and high affinity toward water and organic solvents, has been used in various applications in industrial production to color textile industries, printing, paper and medical disinfectants [1]. Dye-related water contamination is hazardous to aquatic life and mutagenic to humans [2].…”

“…The same information is regarding the changes in lower band gap values-based material CoAl-LDH [14]. Rhodamine B was successfully destroyed by the polyoxometalate "XM12O40" (X = P, Si, M = W, Mo) [1]. Using CoW-TiO2 nanocomposite made from Keggin-type cobaltsubstituted phosphotungstates, Rafiee et al [15] investigated the degradation of methyl orange, and when exposed to UV light, carbon nitride was produced with H3PW12O40 doping [12].…”

The modification catalysts of layered double hydroxide (LDH) with polyoxometalate based on Keggin type were prepared and characterized using X-Ray, FTIR, and SEM to confirm the layered double hydroxide structure. Intercalation was successfully synthesized and showed a heterogeneous aggregate resulted from SEM analysis. The degradation parameters of LDH pristine and LDH composite were determined by observing a number of factors such as pH, catalyst weight, and degradation time. The modification material resulted by preparation material LDH and polyoxometalate (POM) successfully resulted in the lower band gap value compared to material pristine LDH allowing LDH polyoxometalate as photocatalysts to show good photocatalytic activities. The NiAl-SiW12O40 material had the highest percentage of degradation removing Congo Red up to 86% degradation when compared to another composite material, yet it was still significantly better than LDH pristine. The result showed that the LDH composite presented excellent photocatalytic activity in reducing Congo Red.
