Carboxylic acid-modified metal oxide catalyst for selectivity-tunable aerobic ammoxidation
Nature Communications, 2018 Precisely controlling the surface properties of base-metal oxide catalysts to tune the reaction selectivity remains a challenge. Here, the authors show that a green modification of manganese oxide surface with carboxylates can be used to tune the ...

Unravelling the surface chemistry of metal oxide nanocrystals, the role of acids and bases [PDF]
, 2014 We synthesized HfO2 nanocrystals from HfCl4 using a surfactant-free solvothermal process in benzyl alcohol and found that the resulting nanocrystals could be transferred to nonpolar media using a mixture of carboxylic acids and amines.

Selective reduction and homologation of carbon monoxide by organometallic iron complexes
Nature Communications, 2018 Metal-mediated activation of CO for C-C coupling reactions is a valuable approach to carbon monoxide valorization. Here, the authors use low-coordinate iron(II) complexes for the selective scission and homologation of CO affording unusual squaraines and ...
