In this study, a new strategy has been produced to use a rotten apple juice as a source for the surface modification of Co 3 O 4 nanostructures, giving rise to efficient electro-catalysts for driving oxygen evolution reaction (OER) at relatively low over potential. We have studied the 2 morphology, chemical composition, and crystalline aspects of C...
The sluggish kinetics of the oxygen evolution reaction (OER) is one of the most limiting factors for the development of many “green” electrochemical devices. Expensive ruthenium and iridium oxide electrodes are often used as advanced electrocatalysts to overcome this limitation. However, these materials are rare in nature, which further limits the ...
Multi-scale regulation strategies ranging from electronic behavior regulation to crystal structure modulation to micro-nano structure construction can effectively improve the properties of materials, thereby bringing about significant improvements in performance. In this paper, we successfully constructed (Co1-xNix)3O4 with Ni substitution (x) uniq...

Atomically dispersed and nitrogen-coordinated single metal atom implanted into the carbon substrate holds great promise as Pt-liked catalysts for oxygen reduction reaction (ORR). However, the complicated synthetic procedures of single atomic catalysts heavily limit their widespread applications. Herein, the atomically dispersed Co stabilized by nit...
The bottom-up design strategy can more rationally optimize the composition and structure of the materials to impart excellent oxygen evolution reaction (OER) performance. Heterostructures can modulate electronic behavior through interface construction to optimize materials properties for superior OER performance. In this paper, we created abundant ...

Hydrogen production by water electrolysis has received extensive attention, mainly due to the fact that the process does not emit carbon dioxide and other pollutants. Whereas, the kinetic process of the anodic oxygen evolution reaction (OER) is very sluggish due to the four-electron proton coupling mechanism, which seriously affects the hydrogen pr...

The design of highly active, economical and highly stable electrocatalysts for the oxygen evolution reaction (OER) is very important for realizing sustainable energy conversion. Herein, a Cu2O/NiFeCo layered double hydroxide electrode on a copper foam (CF) with a nanoarray structure (Cu2O/NiFeCo LDH/CF) is fabricated by using Cu(OH)2 on CF (Cu(OH)2...
