Carbon quantum dots decorated Cu2O composite for electrochemical hydrogen evolution

Abstract

It is generally desired that efficient and inexpensive hydrogen evolution reaction (HER) properties of nanoparticles be developed for future renewable energy systems. Hydrogen evolution through water electrolysis is an important energy conversion technique, particularly for some variable energy systems. The practical application is restricted because of its lower energy transformation ability and expensive electrocatalyst. So, Carbon based metal hybrid material would be the suitable candidate for electrocatalytic hydrogen production owing to its distinctive properties like electrical conductivity, distinct edge locations, high chemical stability, and synergetic effects have extensive potential. Carbon quantum dots commonly denoted as CQDs are minuscule carbon nanoparticles with distinctly eccentric features that have found widespread use in a variety of industries in recent years. Thus, we have designed a catalyst of bimetallic oxide decorated with CQDs for systematic hydrogen production in a basic medium.
