In this project, lanthanum oxide doped tin oxide (SnLa₂O₅) nanomaterial was prepared and characterized morphologically and physiochemically by different techniques. The catalytic performance of SnLa₂O₅ was assessed toward catalytic reduction of 4-nitrophenol (4-NP), methyl orange (MO), Congo red (CR), methylene blue (MB) and potassium ferricyanide (K₃[Fe(CN)₆]). SnLa₂O₅ was found to be efficient for K₃[Fe(CN)₆] in the presence of NaBH₄, which reduced in only 8.0 min. SnLa₂O₅ was further wrapped in carboxy methyl cellulose mixed calcium alginate (CMC-Alg) hydrogel beads because the powder catalyst cannot simply recover from reaction media to recycle and use again. SnLa₂O₅ wrapped CMC-Alg (SnLa₂O₅/CMC-Alg) was assessed for detail analysis of K₃[Fe(CN)₆] reduction. The effect of NaBH₄, K₃[Fe(CN)₆] concentration and amount of catalyst was optimized using SnLa₂O₅/CMC-Alg. The amount of catalyst has positive impact on catalytic performance and efficiency of SnLa₂O₅/CMC-Alg. The kinetic study revealed that K₃[Fe(CN)₆] reduction by SnLa₂O₅ and SnLa₂O₅/CMC-Alg was fast, which completed in 8.0 and 4.0 min with rate constant of 0.4283 min⁻¹ and 0.7461 min⁻¹, respectively. These findings indicated that the developed nanocatalysts would be talented and proficient nanocatalyst for K₃[Fe(CN)₆] reduction. The virtuous efficiency along with cost-effective and simple treatment route of the developed nanocatalyst have prospect to compete and replace the reputable commercial catalysts.
