The synthesized catalysts were characterized by X-ray powder\n diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), brunauer-emmett-teller (BET), scanning electron microscopy (SEM), transmission electron microscope (TEM), temperature-programmed desorption, and thermal gravimetric analysis (TGA\/DTA) techniques. Methyl levulinate is an important\n chemical feedstock and its production through a catalytic route has been explored in this work. All the synthesized catalysts show excellent catalytic activity towards liquid-phase esterification of levulinic acid (LA) in atmospheric pressure under non-corrosive and mild conditions. The various\n reaction parameters like the effect of sulfate content, reaction temperature, reaction time, molar ratio of reactants, and prepared catalyst weights are optimized to get the highest conversion and selectivity of methyl levulinates. Among them, as prepared 6.9% SO<jats:sup>2\u2212<\/jats:sup><jats:sub>4<\/jats:sub>\n \/SnO<jats:sub>2<\/jats:sub> catalyst exhibits the highest conversation of levulinic acid (98%) and more selectivity towards methyl levulinate (100%). The catalytic stability and recyclability of the most active nanocatalysts were performed up to five successive runs and proves less variation in the catalytic\n activity.<\/jats:p>","DOI":"10.1166\/jnn.2021.19323","type":"journal-article","created":{"date-parts":[[2021,11,5]],"date-time":"2021-11-05T23:06:18Z","timestamp":1636153578000},"page":"3237-3248","source":"Crossref","is-referenced-by-count":0,"title":["Efficient Conversion of Levulinic Acid to Methyl Levulinate Over SO<sup>2\u2212<\/sup><sub>4<\/sub>\/SnO<sub>2<\/sub> Nanocatalysts"],"prefix":"10.1166","volume":"21","author":[{"given":"Durai","family":"Mathivanan","sequence":"first","affiliation":[{"name":"Graduate Institute of Manufacturing Technology, National Taipei University of Technology, Taipei, 106335, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Durai","family":"Mani","sequence":"additional","affiliation":[{"name":"Center for Nanoscience and Technology, Anna University, Chennai 600025, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kumaravel","family":"Saranraj","sequence":"additional","affiliation":[{"name":"Electrical and Electronics Engineering, Panimalar Engineering College, Chennai 600123, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saravanan","family":"Archana","sequence":"additional","affiliation":[{"name":"Electronics and Communication Engineering, Shreenivasa Polytechnic College, B.
