Metal-based catalysts ranging from nanoparticles (NPs) to the atomic level usually exhibit varying catalytic performance. The underlying size effect is both fascinating and evident. This study thoroughly investigates size-dependent effects of Fe-based on transfer hydrogenation (CTH) furfural (FF) at level. Fe was precisely loaded onto N-doped porous carbon in three forms: single atoms (Fe-SAs/NC), clusters (Fe-ACs/NC), (Fe-NPs/NC). achieved through meticulous control iron precursor...
A new synthetic method for disulfides and 3-sulfenylchromones is reported. This innovative approach based on the tetrabutylammonium iodide (TBAI)/H 2 SO 4 reduction system using sodium sulfinate as key component, thus eliminating need thiols redox reagents commonly used in traditional methods. Various were obtained moderate to excellent yields through this methodology. Mechanistic studies indicate that thiosulfonates play an important role reaction process.
Currently, designing highly efficient catalysts for biomass hydrogenation at low temperatures remains a significant challenge. This paper proposes straightforward solvent-treatment strategy to create rich oxygen vacancies (OV), facilitating the loading of ultra-small (1.6 nm) Pt nanoparticles (NPs) onto metal-organic framework (MOF) (LaQS) with OV (LaOV-r). Consequently, bifunctional Pt2/LaOV-r catalyst, featuring Lewis acid and metal sites, was synthesized. Under mild conditions (80 °C),...
