Element-dependent effects of alkali cations on nitrate reduction to ammonia

Synergy of Photogenerated Electrons and Holes toward Efficient Photocatalytic Urea Synthesis from CO2 and N2

“…As shown in X-ray absorption near-edge structure (XANES) profiles (Figure S11), the absorption edge position of Ni 1 -CdS/WO 3 is between those of Ni foil and NiS, suggesting the oxidized state of Ni species in Ni 1 -CdS/ WO 3 . [33,34] The Ni K-edge spectra in R space were further illustrated in Figure 1d. Apparently, Ni 1 -CdS/WO 3 displayed an obvious peak at ~1.8 Å, which could be ascribed to the NiÀ S coordination.…”
