Switching of support materials for the hydrogenation of nitroarenes: A review

The requirement of green, sustainable, and prudent chemical procedures is one of the bottlenecks in synthetic organic chemistry. Nanostructured materials have the promise to fill the gap between homogeneous and heterogeneous catalysis and can offer benefits without compromising the selectivity in forming the desired products. Advancement of sustainable and green chemical processes under environmental benign conditions is one of the immense interests in modern organic chemistry. Significantly, the hydrogenation of nitroarenes is one of the most important useful catalytic processes in the fine and bulk chemical industry. The most recent advancement of catalysts with supported metal nanoparticles has prompted their enormous accomplishments in the course of the most recent years, provoking their noteworthy applications as "standard" catalysts. Currently, this topic has gotten a lot of consideration. However, despite the fact that support materials have a great diversity in the catalysts for the reactions and modifications, a systematic rationalization of the field is lacking. In this review, we cover and categorize the recent progress in support materials tuning strategies to enhance catalytic performance for the hydrogenation of nitroarenes. Also, importance of support materials in the heterogeneous catalytic hydrogenation of nitroarenes is discussed.
