▎ 摘　　要

NOVELTY - Multicomposite compounds comprise metal-organic frameworks, and first graphene-nanoplatelets. The metal-organic framework comprises a first metal atom, a second metal atom, and an organic linkers. The first metal atom (M1) and second metal atom (M2) is different from each other. The organic linking group is derived from 1,3,5-benzene tricarboxylic acid. USE - The multicomposite compound is useful as electrode for oxygen generator (claimed). ADVANTAGE - The multi-composite compound: has charge transfer resistance (Rct) of 1.0-5.0 ~o at overpotential of 1.5 V, high electrical conductivity and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) electrode comprising multicomposite compound; and (2) oxygen generator comprising cathode i.e. hydrogen generating reaction electrode, anode comprising electrode, and electrolyte i.e. water.
