Strong metal–support interactions between atomically dispersed Ru and CrOx for improved durability of chlorobenzene oxidation

“…Previous studies indicated that strong interaction between atomically dispersed or other forms of noble metals and catalyst support makes the noble metals harder to reduce. 50,51 The reduction peaks of 1RuCr 2 O 3 -M for Cr 6+ to Cr 3+ (170-370 °C) almost vanished aer Ru application but were different with Cr 2 O 3 -P and 1RuCr 2 O 3 -P. This implies that the combination of Ru and oxygen in 1RuCr conclusion derived from Raman, XPS, and H 2 -TPR of the SMSI between Ru and lattice oxygen of 1RuCr 2 O 3 -M.…”

Efficient Electrochemical Nitrogen Fixation over Isolated Pt Sites

“…The WO 3 nanoplates were prepared via a hydrothermal method and Pt species decorated WO 3 nanoplates hybrids were obtained by in situ photodeposition procedure according to our previous work (Scheme S1, Supporting Information). [ 22 ] Samples loaded with isolated Pt atoms and Pt nanoparticles are named as Pt SAs/WO 3 and Pt NPs/WO 3 , respectively. As shown in Figure S1, Supporting Information, Pt SAs/WO 3 keeps the cuboid geometry and uniform shape like WO 3 nanoplates (Figure S2, Supporting Information).…”

“…On the basis of our previous work, by further considering the concentration of water molecules in different regions, two typical H 2 WO 4 (100) surfaces, with and without the top water layer, were considered as the possible prototypes for water‐rich and water‐poor zones on the surface, respectively (Figure S23 and Table S2, Supporting Information). [ 22 ] On the two typical H 2 WO 4 (100) surfaces, several isolated Pt anchoring sites were constructed and the related energies were calculated. It is interesting to note that, in the water‐rich zone, the isolated Pt atom prefers to occupy the bridge site between one oxygen atom from top layer water and one neighboring oxygen atom from top W−O polyhedra, denoted as Pt−2O (Figure S24, Supporting Information), while in the water‐poor zone, the isolated Pt atom coordinates three neighboring oxygen atoms from W−O polyhedra, denoted as Pt−3O (Figure S25, Supporting Information).…”

Optical microfiber or nanofiber: a miniature fiber-optic platform for nanophotonics

“…Owing to the localized surface plasmon resonance (LSPR), a considerable fraction of energy can be confined to the interface of the Au NPs and the optical MNF, leading to a reduction in the bending loss. In addition, it is found that, compared with suspended MNF, in a substrate-supported MNF, the bending radius should be larger to guarantee a low propagation loss [230] .…”
