However, the current development of green hydrogen energy is severely restricted by the slow progress of core technologies. Based on this, our study is based on the research of new catalytic systems and has established a high\u2010density active interface with metal atoms arranged densely. It has solved the kinetic limitation issue of OER. The result has achieved a perfect preparation by the combination of growing transition metal cobalt and rare earth cerium oxides (Co\u2013CeO\n                    <jats:sub>x<\/jats:sub>\n                    ) on the surface of graphdiyne (GDY). Under the strong induction of GDY, a clearly structured high\u2010density metal atom interface was formed. Such an atomic heterostructure maximally exposes the active sites and enables dynamic reversible incomplete charge transfer at the interface, significantly promoting the adsorption of key intermediates. The Co\u2013CeO\n                    <jats:sub>x<\/jats:sub>\n                    \/GDY catalyst exhibits outstanding oxygen evolution reaction (OER) performance under alkaline conditions with a small overpotential of 161\u00a0mV at 10\u00a0mA\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    and a high turnover frequency of 2.38\u00a0O\n                    <jats:sub>2<\/jats:sub>\n                    \u00a0s\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 300\u00a0mV.
