The present research Project aims the utilization of porous metal oxides (PMO) as heterogeneous catalysts for lignin hydrogenolysis reaction (generating phenols as main products) and model molecules for lignin chemical bonds (mostly aryl-aryl and aryl-O-aryl) using subcritical water/formic acid as solvent and hydrogen source respectively. The PMOs proposed will be doped with the transition metals Fe, Cu, Ni and Nb. The choice of these metals is mostly by its low cost if compared with the ones currently used in the lignin depolymerization (Pt and Pd) and for its already demonstrated catalytic activity for formic acid decomposition or for its activity in lignin depolymerization using other hydrogen sources. The choice of formic acid as hydrogen source is due to it is an abundant by-product of the lignocellulosic biomass acid hydrolysis. As results and perspectives of this project is expected the advance of biomass chemistry, mostly in the lignin depolymerization reaction for obtainment of new renewable carbon sources, and in case of success the transfer of this technology for the industry.
