Nanophase-Separated Copper–Zirconia Composites for Bifunctional Electrochemical CO2 Conversion to Formic Acid

“…The HAXPES profile of Cu#ZrO 2 in the Zr-3d core region is consistent with the reported data of ZrO 2 (Figure C) . The Zr 0 3d 5/2 emission peak positioned at 179.5 eV on the HAXPES profile of Cu 51 Zr 14 was not visible on that of Cu#ZrO 2 , indicating that the metallic Zr 0 in Cu 51 Zr 14 was fully oxidized to ZrO 2 in Cu#ZrO 2 . , Moreover, HAXPES has confirmed that the Cu phase in Cu#ZrO 2 retained the metallic state of Cu 0 , the same as in the Cu 51 Zr 14 precursor alloy (2p 3/2 : 932.6 eV; 2p 1/2 : 952.5 eV) (Figure D).…”

Microorganism@UiO-66-NH2 Composites for the Detection of Multiple Colorectal Cancer-Related microRNAs with Flow Cytometry

“…In the yeast@UiO-66-NH 2 composites, the Zr 3d 5/2 and Zr 3d 3/2 are observed at around 182.57 and 185.02 eV in high-resolution XPS spectrum of Zr 3d (Figure B), respectively, indicating the existence of Zr 4+ . , The peaks at 182.57 and 185.02 eV were assigned to the Zr–O, and Zr–N bond, respectively. This is similar to the results reported in the literature to the formation of ZrO 2 and ZrN. , Figure C is the high-resolution XPS spectrum of C 1s, the peaks at 284.33 eV, 285.64 eV, and 287.20 eV are assigned to the C–C or C–H, carboxylate carbon (OCO) and carbonyl carbon (CO) bonds of the yeast cell wall functional groups. The peaks, located at 531.02 and 532.01 eV in the O 1s spectrum (Figure D), were assigned to CO in carboxylic groups.…”

“…This is similar to the results reported in the literature to the formation of ZrO 2 and ZrN. 53,54 55 As shown in Figure 3E, the peaks at 399.47 and 402.07 eV are attributed to nitrogen in the C−N bond and protonated amino groups (NH 3 + ), respectively. 56 As shown in Figure 3F, the two peaks at 162.58 and 163.84 eV were assigned to the S 2p 1/2 and S 2p 3/2 , respectively.…”

The Visible Light Absorption Mechanism for Cubic Zirconia by Cobalt‐Ion Implantation

“…[ 31 ] The Zr 3d spectral peak in the nonimplanted surface splits into Zr 3d 5/2 and Zr 3d 3/2 as shown in Figure 3e,f. [ 32 ] There is almost no change in the peaks of Zr 3 d 5/2 and Zr 3 d 3/2 after implantation, indicating that the Zr ion is stable before and after implantation.…”
