ABSTRACT
One of the most essential chemical processes that is utilized in the manufacturing of a great deal of contemporary goods is called heterogeneously catalyzed reactions, and it is also one of the most fascinating. Metallic nanostructures are heterogeneous catalysts for range reactions due to their huge surface area, large assembly of active surface sites, and quantum confinement effects. Unprotected metal nanoparticles suffer from irreversible agglomeration, catalyst poisoning, and limited life cycle. To circumvent these technical disadvantages, catalysts are frequently spread on chemically inert materials like as mesoporous Al2O3, ZrO2, and different types of ceramic material. In this research, plentiful bauxite residue is used to create a low-cost alternative catalytic material. We have hydrogenated p-Nitrophenol to p-Aminophenol on bauxite residue (BR) supported silver nanocomposites (Ag NCs). The phase and crystal structure, bond structure and morphological analysis of the developed material will be done XRD, FTIR, and SEM-EDX respectively. The ideal conditions were 150 ppm of catalyst, 0.1 mM of p-NP, and 10 minutes overall up-to 99% conversion of p-NP to p-AP. A multi-variable predictive model created using Response Surface Methodology (RSM) and a data-based Artificial Neural Network (ANN) model were found to be the best ways to predict the maximum conversion efficiency. ANN models predicted efficiency more accurately than RSM models, and the strong agreement between model predictions and experimental data was indicated by their low relative error (RE0.10), high regression coefficient (R2>0.97), and Willmott-d index (dwill-index > 0.95) values.

Suraj K. Tripathy
Dr. Suraj Kumar Tripathy, is a well experienced member in the field of wastewater treatment. Recently he has developed novel strategy for wastewater recycling by removing Chromium [Cr(III)] from water, utilizing the treated water for agricultural purposes and the saturated adsorbent used as the catalyst for p-nitrophenol reduction was successfully incorporated for sustainable environmental application. Removal of Cr(III) by adsorption on Cymbopogon flexuosus waste material entrapped within sodium alginate beads was investigated. Moreover he has introduced an optimization methodology to investigate for optimization of process parameters during removal of Cr(III) from aqueous solution. His generous knowledge on wastewater treatment technology will lead us to design and demonstrate the developed set-up to the industry. In addition to that well experienced on IPR generation will lead to transfer the technology to the interested company. Dr. Tripathy published more than 70 papers in several high impact SCI/SCOPUS journals also filed 6 patents on his name. He has awarded as Eminent Scientist of the Year 2021 from National Environmental Science Academy. Dr. Tripthay recently awarded with Distinguished Researcehr Awarard from National Environmental Science Academy.
