Amorphous Y(OH)₃-promoted Ru/Y(OH)₃ nanohybrids with high durability for electrocatalytic hydrogen evolution in alkaline media

Abstract

A novel Ru/Y(OH)3 nanohybrid with high activity and excellent durability for electrocatalytic hydrogen evolution in alkaline media was developed.

Inner structure and dynamics of microgels with low and medium crosslinker content prepared via surfactant-free precipitation polymerization and continuous monomer feeding approach

“…17,18 Microgel preparation via a continuous monomer feeding approach (feeding synthesis) is assumed to lead to a more homogeneous crosslinker distribution. [19][20][21][22] This was confirmed by a homogeneous elastic modulus and a homogeneous distribution of the embedded nanoparticles within the microgel. 21 Properties of the microgel are closely related to their internal structure.…”

Synthesis, characterization and application of defective metal–organic frameworks: current status and perspectives

“…112 Recently, novel low-dose electron microscopy techniques have been developed for the atomic resolution imaging of MOFs. 113 Some bulk and local MOF structures have already been unravelled by HR-(S)TEM. 113 Liu et al 48 reported the real-space observation of missing linker and missing cluster defects in UiO-66, using a combination of lowdose electron microscopy techniques and electron crystallography.…”

Ruthenium Nanoparticles for Catalytic Water Splitting

“…In addition to C-based supports, metal or semimetal-based materials,s uch as MoS 2 , [98] MoO 2 , [99] TiO 2 , [100] W, [101] Si, [102] Te , [103] Y(OH) 3 , [104] or CeO 2 , [105] have also been used as supports. For example,Q iao et al described an extremely active catalyst under basic conditions (1 m KOH).…”
