CuO/Cu nanorod skeleton supported Ru-doped CoO/NC nanocomposites for overall water splitting.

High overpotential and low stability are major challenges for hydrogen evolution reaction (HER)/oxygen evolution reaction (OER). Tuning the electronic structure of catalysts is regarded as a core strategy to enhance catalytic activity. Herein, we report CuO/Cu nanorod skeleton supported Ru doped cobalt oxide/nitrogen-doped carbon nanocomposites (Ru-CoO/NC/CuO/Cu, denoted as RCUF) as bifunctional catalysis.

Surface reconstruction of RuO/CoO amorphous-crystalline heterointerface for efficient overall water splitting.

The rational construction of amorphous-crystalline heterointerface can effectively improve the activity and stability of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Herein, RuO/CoO (RCO) amorphous-crystalline heterointerface is prepared via oxidation method. The optimal RCO-10 exhibits low overpotentials of 57 and 231 mV for HER and OER at 10 mA cm, respectively.

Preparation of 2D nitrogen-doped magnetic FeC/C by in-situ self-assembled double-template method for enhanced removal of Cr(VI).

Porous carbon, which can be functionalized, is considered as a potential carbon material. Herein, two-dimensional (2D) nitrogen-doped magnetic FeC/C (NMC) was prepared by a simple carbonization method using potassium humate (HA-K) as raw material. Remarkably, two templates, g-CN and KCl, were formed in situ during the carbonization process, which provide the necessary conditions for the formation of 2D NMC.
