By using an isotopic-pulse labeling technique in conjunction with micro-Raman spectroscopy identification, we visualized the growth dynamics regarding the nucleation, growth, and coalescence during the fast growth of large single-crystalline graphene domains. A high growth rate of 320 μm/min for the growth of millimeter-sized graphene on Cu foil was realized by tuning the carbon-source supply.

In this study, an Ir/Ce0.9La0.1O2 catalyst showed higher activity and stabler performance for methane dry reforming reaction than the Ir/CeO2 catalyst. The observation was attributed to the stronger metal–support interaction in the Ir/Ce0.9La0.1O2 catalyst stabilizing the catalyst structure and improving the oxygen storage capacity, leading to negligible aggregation of Ir nanoparticles and the Ce0.9La0.1O2 support at high temperatures, as well as the rapid removal of carbon deposits at the Ir-Ce0.9La0.1O2 boundaries.

Rambutan-like hierarchically heterostructured CeO2-CuO hollow microspheres synthesized by a facile one-pot template-free hydrothermal approach exhibit superior performance, both as electrode materials for supercapacitors and as Cu-based catalysts for dimethyldichlorosilane (M2) synthesis via the Rochow reaction.

We report the in situ synthesis of single- and double-shelled NiCo2O4 hollow spheres through a one-pot solvothermal method assisted by xylose. The present hollow spheres lead to superior specific capacitance and cycling stability in supercapacitor electrodes.

Sponge-like nickel phosphide–carbon nanotube (NixP/CNT) hybrid electrodes were prepared by facile cyclic voltammetric deposition of amorphous NixP catalysts onto three-dimensional (3D) porous CNT supports. NixP/CNTs exhibit superior catalytic activity for sustained hydrogen evolution in acidic, neutral, and basic media.

Crystallographic behaviors of PbZr1–xTixO3 (PZT) thin film caused by modified interfacial effects are thoroughly studied by integrated perspectives from ab initio physical modeling to experimental demonstration; these behaviors can significantly increase the performance of flexible energy harvesters by ~500%, compared to single crystal slaps. Phase balance and crystallinity, as well as the crystal orientation of PZT film at morphotropic phase boundary (MPB), can be clearly modulated by nanointerfacial structure and polarization.

The formation of two-dimensional magnetic nanodot arrays was observed by in situ grazing-incidence small-angle X-ray scattering to reveal structural information during nanosphere lithography. We found that the dot shape changed from cylindrical to conical during the etching process and that the magnetic properties showed a proportional dependency of the coercivity on the dot size.

A graphene membrane Li-air battery with high performance has been demonstrated in ambient conditions. The battery's high storage capacity and unique O2/H2O selectivity are attributed to its large specific surface area and network of highly tortuous hydrophobic channels.
