Sn4P3/reduced graphene oxide nanocomposites exhibited high selectivity for CO over a wide potential range from −2.2 V to −2.5 V vs. Ag/Ag+. The maximum faradaic efficiency for CO can reach 96.6% with a high current density of 68.0 mA cm−2. The high efficiency and selectivity can be attributed to the modified electronic structure of Sn sites, the small Sn4P3 nanoparticles and their dense packing in a conductive matrix, leading to a high density of active sites for adsorbing CO2 and stabilizing the CO2˙− intermediate.

Ultrathin metal–organic framework (MOF) nanosheets were fabricated by a surfactant-mediated coordination strategy through a pseudo-assembly process. The thickness of the nanosheets could be tuned from 3 nm to 60 nm by varying the hydrophobic chain length of the surfactant. Ru nanoparticles supported on the nanosheets exhibited superior catalytic activity for hydrogenation of levulinic acid to γ-valerolactone. [ABSTRACT FROM AUTHOR]
