Amorphous nickel borate as a high-efficiency cocatalyst for H2 generation and fine chemical synthesis

Nickel Boride (NixB) Nanocrystals: From Solid-State Synthesis to Highly Colloidally Stable Inks

“…The O1 s spectra further support the different oxidation behavior of the two materials (Figure k). , In fact, for Ni 3 B, the O1 s line peaks at a BE of ∼532, a value typical for nickel oxide, while for Ni 2 B the maximum intensity at ∼533 eV points to boron oxide. ,,, …”

“…In the Ni 3 B NCs, the intensity of the component corresponding to metallic Ni is much lower than that of Ni 2+ , implying that the oxidation layer (NiO and Ni­(OH) 2 on the outer surface) is larger than for Ni 2 B, where the component due to metallic Ni is dominant. Conversely, in the B1 s photoemission line (Figure j), the contribution due to oxidized B (BE ∼ 192 eV) − is negligible in Ni 3 B, identifying B 0 (BE ∼ 188 eV) , as the primary boron species. In Ni 2 B instead, the relative intensity of the component due to B–O bonds is significantly higher than that corresponding to B 0 .…”

Visible-light-driven anaerobic oxidative upgrading of biomass-derived HMF for co-production of DFF and H2 over a 1D Cd0.7Zn0.3S/NiSe2 Schottky junction

“…Cd 0.7 Zn 0.3 S/NiSe 2 4% shows a notably higher photocurrent density than blank Cd 0.7 Zn 0.3 S, indicating that the loading of NiSe 2 to create a Schottky junction could efficiently inhibit the recombination of photogenerated electron-hole pairs. [59][60][61] Meanwhile, electrochemical impedance spectroscopy (EIS) was used to investigate the impact of NiSe 2 deposition on the kinetics of charge migration. [62][63][64] As illustrated in Fig.…”
