Multilayer and open structure of dendritic crosslinked CeO 2 -ZrO 2 composite: Enhanced photocatalytic degradation and water splitting performance

Novel Fe2O3@CeO2 Coreshell‐based Electrochemical Nanosensor for the Voltammetric Determination of Norepinephrine

“…The obtained results of XRD are shown in Table S. The samples’ X‐ray patterns illustrate that the crystal structure of the CeO 2 (JCPDS No.34‐0394) is cubic . Once α‐Fe 2 O 3 is introduced into an α‐Fe 2 O 3 /CeO 2 sample, the lattice of CeO 2 is distorted, and, consequently, a shift occurs in the typical peaks of the CeO 2 phases .…”

Anchoring Ni2P on the UiO‐66‐NH2/g‐C3N4‐derived C‐doped ZrO2/g‐C3N4 Heterostructure: Highly Efficient Photocatalysts for H2 Production from Water Splitting

“…To gain more insight into the chemical states of these atoms in the composite, the high‐resolution XPS spectra of Zr 3d, C 1s, N 1s, Ni 2p, and P 2p were measured. In the Zr 3d high‐resolution spectrum (Figure a), the binding energies (BEs) at 182.8 and 184.8 eV were ascribed to Zr 3d 5/2 and Zr 3d 3/2 in the Zr 4+ oxidation state, consistent with other available data for ZrO 2 . For the C 1s spectrum (Figure b), the BEs at 284.8 and 288.6 eV originate from the C−C and N‐C=N bonds, respectively .…”

“…However, the shortcomings of the wide band gap and the poor utilization of solar light limit its application. Constructing heterojunctions between ZrO 2 and semiconductors with staggered band structures, such as TiO 2 , CuO, CeO 2 , Bi 2 S 3 , and g‐C 3 N 4 , can compensate for the defects of the wide band gap . It has been found that the energy levels of g‐C 3 N 4 and ZrO 2 can be properly matched to ensure the formation of a type II heterostructure, which can promote the transfer of photoexcited electrons from g‐C 3 N 4 to ZrO 2 and photoexcited holes from ZrO 2 to g‐C 3 N 4 , thus achieving an efficient charge separation.…”

The three-dimensional ordered macroporous structure of the Pt/TiO2–ZrO2 composite enhanced its photocatalytic performance for the photodegradation and photolysis of water

“…All chemicals were of analytical grade (AR) and used as received without purication; secondary distilled water was employed for all the experiments. 20 was impregnated with 8 mL methanol, stirred for 30 min, then ltered, and naturally dried. Then, n-butoxide and titanium tetraisopropoxide were mixed uniformly at a volume ratio of 1 : 4.…”
