SnAg(2)O(3)-Coated Adhesive Tape as a Recyclable Catalyst for Efficient Reduction of Methyl Orange

Silver oxide-doped tin oxide (SnAg(2)O(3)) nanoparticles were synthesized and different spectroscopic techniques were used to structurally identify SnAg(2)O(3) nanoparticles. The reduction of 4-nitrophenol (4-NP), congo red (CR), methylene blue (MB), and methyl orange (MO) was studied using SnAg(2)O(3) as a catalyst. Only 1.0 min was required to reduce 95% MO; thus, SnAg(2)O(3) was found to be effective with a rate constant of 3.0412 min(−1). Being a powder, SnAg(2)O(3) is difficult to recover and recycle multiple times. For this reason, SnAg(2)O(3) was coated on adhesive tape (AT) to make it recyclable for large-scale usage. SnAg(2)O(3)@AT catalyst was assessed toward MO reduction under various conditions. The amount of SnAg(2)O(3)@AT, NaBH(4), and MO was optimized for best possible reduction conditions. The catalyst had a positive effect since it speed up the reduction of MO by adding more SnAg(2)O(3)@AT and NaBH(4) as well as lowering the MO concentration. SnAg(2)O(3)@AT totally reduced MO (98%) in 3.0 min with a rate constant of 1.3669 min(−1). These findings confirmed that SnAg(2)O(3)@AT is an effective and useful catalyst for MO reduction that can even be utilized on a large scale for industrial purposes.
