[EN] At difference with noble metals, the oxophylic character of non-noble metals strongly facilitates the rupture of the N-O bonds in nitrobenzene, yielding nitrosobenzene as primary reaction intermediate. By combining ...

[EN] To achieve high-loading of stable subnanometric metal clusters on solid carriers is a challenge since those small metal clusters have strong tendency to sinter into larger nanoparticles. Development of facile synthesis ...

[EN] Bimetallic CuFe nanoparticles covered by thin carbon layers were developed as a potential substitute for noble metal catalysts and have been used for chemoselective hydrogenation of 5-(hydroxymethyl)furfural (HMF) to ...

Nickel supported on silica-alumina is an efficient and reusable photocatalyst for the reduction of CO2 to methane by H-2, reaching selectivity above 95% at CO2 conversion over 90%. Although NiO behaves similarly, it undergoes ...

[EN] In this thesis, I have discussed the synthesis of Cu nanoparticles and their applications in C-N coupling reactions. I find that Cu nanoparticles will decompose into Cu clusters and Cu clusters are the real active ...

[EN] Identification of active sites in heterogeneous metal catalysts is critical for understanding the reaction mechanism at the molecular level and for designing more efficient catalysts. Because of their structural ...

[EN] Aluminosilicate boggsite (Si/Al-BOG) has been hydrothermally synthesized without adding org. structure-directing agents (OSDAs) in the synthesis gel using the borosilicogermanium ITQ-47 (Si/B-ITQ-47) zeolite as seeds. ...

[EN] We show a facile method to prepare surface-clean monodispersed small and stable CuOx nanoparticles with controllable average sizes from below 1 nm up to similar to 5 nm without using bulk capping agent. Structural and ...

[EN] Single metal atoms and metal clusters have attracted much attention thanks to their advantageous capabilities as heterogeneous catalysts. However, the generation of stable single atoms and clusters on a solid support ...

[EN] Ruthenium nanoparticles with a core-shell structure formed by a core of metallic ruthenium and a shell of ruthenium carbide have been synthesized by a mild and easy hydrothermal treatment. The dual structure and ...
