In this paper, we present the fabrication of Ln2Zr2O7 (Ln = Nd, Pr) ceramic nanostructures with green tea extract (GrTeEx) as novel and efficacious fuel through easy and repeatable route as well as their application in propane-selective catalytic reduction of NOx process (propane-SCR-NOx), for the first time. As-fabricated samples with green tea extract have been examined via diverse kind of techniques. Our outcomes represented the successful production of the pure nanostructured Ln2Zr2O7 (Ln = Nd, Pr) in presence of green tea extract as novel and efficacious fuel. Moreover, the nanostructured samples can be utilized as a potential novel kind of catalysts with desirable efficiency for propane-SCR- NOx. It was found that Pr2Zr2O7 denoted better performance than Nd2Zr2O7 for NOx abatement so that the conversion of NOx in to N2 for Pr2Zr2O7 was 67% and for Nd2Zr2O7 was 56%. Also the concentration of CO production for Pr2Zr2O7 which is inevitable and undesirable product in SCR-NOx process with hydrocarbons such as propane was lower than Nd2Zr2O7.
