▎ 摘　　要

NOVELTY - High specific surface area nickel-iron layered double hydroxide/graphene nanocluster heterojunction, where (1) the NiFeLDHs/graphene oxide nanocluster heterojunction obtained by this method is formed by the accumulation of small-sized NiFe-LDHs nanoclusters on the surface of two-dimensional sheet-type graphene oxide, taking advantage of the advantages of both, comparing with the previous literature, the obtained NiFe-LDHs/graphene oxide nano-heterojunction has a larger specific surface area and can expose more active sites, (2) the NiFe-LDHs/GO nanoclusters obtained by this method have the characteristics of high yield, good dispersion, and not easy to overlap and twist, and (3) the NiFe-LDHs/GO nanoclusters obtained by this method have excellent oxygen evolution catalytic performance and can maintain a high working activity for 24 hours. USE - The high specific surface area nickel-iron layered double hydroxide/graphene nanocluster heterojunction is used in electrolytic water oxygen evolution reaction. ADVANTAGE - The NiFe-LDHs/GO nano-cluster heterojunction has large specific surface area, good stability, and excellent oxygen evolution catalytic performance, and can expose more active sites. It has high yield, good dispersibility, not easy to overlap and characteristics, and has excellent property of oxygen evolution reaction and catalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation of NiFe-LDHs/graphene oxide nano-cluster heterojunction.
