such as CeO2(111), CeO2(200), and CeO2(220). The crystal phase of copper could not be observed due to the lighter atomic weight of Cu with respect to Ce and the similar contrast
Morphological and structural control of amorphous nanomaterials is challenging due to the long-range disordered atomic arrangements. Herein, we firstly propose a controllable self-hydrolyzing etching-precipitating (SHEP) method to fabricate the regular-shaped amorphous Cu2MoS4 nanocages (a-Cu2MoS4 NCs)...
S1.1 in Supporting Information Section 1), reveals that the χmT vs T plot of the pyridine-analog displays no maximum, whereas these plots for the CuXBA compounds exhibit broad maxima at lower temperatures. Due to this difference in the experimental data and the complexity of the halide-...
Msorbate: Molecular weight of sorbate (in this study: Cu = 63.55 g mol−1). [Sorbate]°: Standard concentration of the sorbate (1 mol L−1). γ: Coefficient of activity (unitary for dilute solutions and dimensionless). ΔH∘: Standard sorption enthalpy (kJ mol−1). ΔS∘...
Excessive Cu2+ intake can cause neurological disorders (e.g. Wilson’s disease) and adversely affect the gastrointestinal, liver, and kidney organs. The presence of Cu2+ is strongly linked to the emergence and progression of Wilson's disease (WD), and ac

The atomic force microscopy (AFM) height image proved that CBS nanosheets have an ultrathin thickness of about 3.9 nm (Fig. 1C, D). The energy dispersion spectrometer (EDS) element analysis showed the homogeneous distribution of Bi, Se, and Cu in the nanosheets, indicating that Cu atoms ...

The above results suggest that spontaneous redispersion of Cu NPs in O2-H2O may occur through the oxidation of Cu atoms into atomic Cu-O species, followed by quick hydroxylation into atomic Cu-OH species and final capture by the support. Furthermore, we find that the oxidative redispersion proc...
Studying the atomic structure-activity relationship of catalyst during the CO2RR process is crucial to reveal the intrinsic catalytic mechanism. To assess the chemical state of Cu in the Cuδ+NCN under CO2RR (Fig. 4a), operando XAS was performed (Supplementary Fig. 29), and the CuNCN was ...
