Hydrogen production from formic acid catalyzed by NHC–Cu complexes

Beilstein Journal of Organic Chemistry
The first NHC–Cu-catalyzed decomposition of formic acid (FA) is reported. In the presence of PhSiH3, only hydrogen is generated while CO2 is captured by a silane species.

Facile Synthesis of Ultra-Small Silver Nanoparticles Stabilized on Carbon Nanospheres for the Etherification of Silanes

Nanomaterials
The dehydrocoupling reaction between alcohols and hydrosilanes is considered to be one of the most atom-economical ways to produce Si–O coupling compounds because its byproduct is only hydrogen (H2), which make it extremely environmentally friendly.
