Expanding the I–II–V Phase Space: Soft Synthesis of Polytypic Ternary and Binary Zinc Antimonides

“…Powder XRD data of a “0 min” sample (removed and isolated immediately upon injection) do not show a change in lattice constant, and the peaks are not substantially broadened, which makes the intercalation of Li into the Zn seeds unlikely. This mechanism is consistent with what was observed for LiZnP as well as binary phosphides. ,− …”

Electrocatalytic Activities of Oxygen Reduction Reaction on Pd/C and Pd–B/C Catalysts

“…The electron transfer direction is consistent with a larger electronegativity of the B-element in Pauling scale, that is, EN (Pd) = 2.20 eV, EN (B) = 2.04 eV, as well as a smaller work function (WF) of B, that is, WF (Pd) = 5.2 eV, WF (B) = 4.5 eV. What is more, such an explanation is also in agreement with a previous review, which suggests two directions of electron transfer depending upon the percentage of doped B, that is, from M to B in boron-rich MB x ( x ≥ 2) and from B to M for metal-rich MB x ( x ≤ 2).…”

Evident Enhancement of Photoelectrochemical Hydrogen Production by Electroless Deposition of M-B (M = Ni, Co) Catalysts on Silicon Nanowire Arrays

“…Compared with that of pure B (187.1 eV), the binding energies of 188.6 and 188.3 eV for the elemental boron in Ni–B and Co–B NPs are positively shifted by 1.5 and 1.2 eV, respectively. On the contrary, small negative shifts (0.1–0.2 eV) of the binding energy peaks of the 2p 3/2 core levels of metallic Ni and Co in M-B NPs were observed compared to that of pure Ni (852.8 eV) and Co (778.4 eV). , The shifts of these binding energy peaks of elemental B, Ni, and Co are an indication of electron donation from B to M in the M-B NPs, which is consistent with the trend of electron movement reported for transition metal-rich borides (MB x , M = Ni, Co, x < 2) in amorphous state …”
