Title : Empowering a sustainable future by biomass conversion on single atom catalysis
Abstract:
Efforts have traditionally concentrated on the use of organic carbon as bioenergy, to produce chemicals and fuels. In the past decade, technologies have been developed to recover high-value commodities from renewable feedstocks. Simultaneously, innovative heterogeneous catalytic processes have been proposed to produce chemicals that can be immediately reused from the biowaste to facilitate a renewable future. Several biomass conversion techniques based on supported metal catalysts comply with most green chemistry principles, provided that metal particles and supporting materials leach into the reaction medium. Metal-catalyzed biomass conversion reactions including hydrogenation, dehydrogenation, deoxygenation, and oxidation reactions will achieve by multistep conversion in a single pot, maybe in combination with acid/base-catalyzed reactions like hydrolysis and dehydration reactions. Apart from nanoparticle catalysts (NCs) which contain bulk metals, Single Atom catalysts (SACs) expose all metal atoms on the surface with a 100 % metal utilization rate. Current single metal atom catalysts based on carbon supports relay on in plane doping, limiting the interactions with the substrates due to the geometry and interlayer stacking phenomena of the carbon sheets. Therefore, here, Lignocellulosic biomass conversion using SACs on various supports such as Zeolites, Metal Oxides and Graphene to be addressed.
