Efficient and Robust Hydrogen Evolution: Phosphorus Nitride Imide Nanotubes as Supports for Anchoring Single Ruthenium Sites

“…X-ray powder diffraction (XRD) was performed to verify the phase composition. [12,14] Although TEM and SEM images show little morphological change ( Figure 1e)c ompared to RuCl 3 @HPN and the PN matrix ( Figure S4), the color of Ru SAs@PN is quite different from RuCl 3 @HPN,i mplying that the Ru species has been successfully reduced ( Figure S2). Upon reduction, Ru SAs@PN shows no peaks characteristic of Ru crystals,e ven when the temperature is raised to 773 K (Figure 1d), indicating that the PN 4 tetrahedra short-range units exhibit excellent stability at high temperature.…”

Efficient and Robust Hydrogen Evolution: Phosphorus Nitride Imide Nanotubes as Supports for Anchoring Single Ruthenium Sites

“…As shown in Figure d, the HPN sample has poor crystallinity, which coincides well with the previous report that the HPN only adopts a short‐range regular arrangement. Upon reduction, Ru SAs@PN shows no peaks characteristic of Ru crystals, even when the temperature is raised to 773 K (Figure d), indicating that the PN 4 tetrahedra short‐range units exhibit excellent stability at high temperature . Although TEM and SEM images show little morphological change (Figure e) compared to RuCl 3 @HPN and the PN matrix (Figure S4), the color of Ru SAs@PN is quite different from RuCl 3 @HPN, implying that the Ru species has been successfully reduced (Figure S2).…”

Laser ablation synthesis of new phosphorus nitride clusters from α‐P3N5 via laser desorption ionization and matrix assisted laser desorption ionization time‐of‐flight mass spectrometry

“…[1] Pure, stoichiometric, hydrogen-free and crystalline α-P 3 N 5 was reported in 1996 by Schnick et al [2] Phosphorus nitride (P 3 N 5 ) has the potential for various ceramic applications such as sintering additives, [3] pigments, [4] ionic conductors, [5] microporous materials [6] and for the doping of semiconductors. [7] Recently, nanoscale hollow spheres of P 3 N 5 were synthesized [8] and thin films of amorphous P 3 N 5 were prepared in a low pressure plasma. [9] The structure of α-P 3 N 5 has a three-dimensional network, consisting of corner-sharing PN 4 tetrahedra and it contains two different types of nitrogen atoms (in the ratio 3:2).…”
