Abstract
Abstract Designing a stable and efficient dual‐functional catalyst for the hydrogen evolution and oxygen evolution reactions (HER/OER) is of great significance to the development of hydrogen production by water splitting. This work reports on novel halogen (X = F, Cl, and Br)‐doped carbon dots modifying amorphous cobalt phosphide (X‐CDs/CoP), which can be tuned by the choice of X‐CDs to have urchin, Pinus bungeana , and Albizia julibrissin type structures. The different characteristics of the various X‐CDs led to different formation mechanisms and final structures. As a bifunctional catalyst, urchin‐shaped F‐CDs/CoP crystals achieve superior electrocatalytic performance, exhibiting excellent HER/OER activity…
