A review on development of a greener approach via One-Pot tandem catalysis for biofuels production

Abstract

The escalating human population all over the globe has posed serious threats such asa limited supply of resources (non-renewable), increasing environmental pollution, global warming, food, and energy insecurities, and diminishing petroleum resources. To overcome these problems, much progress has been made in successful one-pot synthesis reactions in combination with the exploitation of advantages of chemoselectivity, regioselectivity, and stereoselectivity of biocatalysts or enzyme promiscuity. In the recent decades, various novel startegies and approaches have been developed intending to address above-mentione global issues. Among various sustainable platforms, one-pot tandem catalytic reactions are reported to be used extensively for synthesizing biofuels such as first generation-, second generation from end-use products which are derived from renewable biomass feedstocks. Further, this one-pot tandem catalytic conversion reaction has surfaced as a sustainable strategy to produce value-added environmentally safe products. Hence, a potential green approach toward the chemical industries. In this contribution, this review discusses the emergence of nanocatalysts for producing renewable energies, an explanation of tandem catalysis and one-pot synthesis, and further the production of biofuels via one-pot tandem catalysis with supportive examples and most important economic aspects and challenges associated with a promising novel approach.
