The aim of the current work was to study the activity of supported palladium catalysts based on porous aromatic frameworks (PAF) in vanillin hydrogenation. and to develop the methods for controlling their activity and selectivity by modifying the PAF structure with various functional groups. Using unmodified PAF-30. its sulfonated derivative PAF-30-SO3H. https://parisnaturalfoodes.shop/product-category/nailcare/
