Guaiacol hydrodeoxygenation in hydrothermal conditions using N-doped reduced graphene oxide (RGO) supported Pt and Ni catalysts: Seeking for economically viable biomass upgrading alternatives

• Novel in-situ HDO strategy with H 2 O as hydrogen source. N-doped reduced graphene oxide (RGO) advanced supports. Comparison among Pt-based and Ni RGO supported catalysts for ‘H -free’ of guaiacol. Innovate route economically viable biomass upgrading. Herein we present an innovative model compounds upgrading via “H -free” hydrodeoxygenation (HDO) reactions. The underlaying idea is to implement a multifunctional catalyst able activate water subsequently use generated the process. In this sense have developed series effective Pt based on N-promoted decorated ceria. reached commendable conversion levels selectivity mono-oxygenated considering very challenging reaction conditions. outperforms when samples are tested as-prepared. However, performance remarkably boosted upon applying pre-conditioning reductive treatment. Indeed, our NiCeO /GOr-N best activity/selectivity balance it deemed promising conduct -free reaction. Overall, “proof-concept” showcases appealing bio-compounds evidencing key role low carbon future.
