Firstly, a series of supports have been synthesized from melamine and urea as a function of precursors ratio and temperature of their condensation. The different synthetic conditions resulted in materials with very different specific surface areas and Ncontaining groups on the surface which influenced Pd deposition. The resulting defects facilitated enhanced electron transfer from nitrogen to Pd due to the close positioning of Pd nanoparticles near nitrogen sites. Consequently, the physicochemical and catalytic properties of the materials were notably impacted.application/pdf38 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/FA dehydrogenationH2CO25-HMF hydrodeoxygenation2'5-DMFinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/embargoedAccesshttps://doi.org/10.1016/j.cattod.2025.115353
