Nickel Nanoparticles wrapped up by graphene layers (Ni@C) has been prepared complicated processes.
Ni@C can function as a platinum-like co-catalyst for photocatalytic hydrogen evolution.
Graphene layers played an essential role in catalytic reaction, such as forming intimate contact with g-C3N4.
This work open up new insights to improve photocatalytic performance by architecturally designing new co-catalysts.
