Abstract
Employing polyoxometalate–based hybrid materials combined from metal–organic complex and polyoxometalate as photocatalysts for pollutant degradation and capacitive electrodes has become a research focus. In order to continue to develop the potential photocatalysts and electrode materials, four octamolybdate–based hybrids constructed from phenanthroline derivative ligands 1, 10 − phenanthroline − 5, 6 − dione (PDO) and 1, 10 − phenanthroline − 5, 6 − diamine (PDA) were isolated. The [β − Mo8O26]4− anions were involved in the structures of 1–3, which were aggregated by Cu ions into a two–dimensional layer decorated by PDO or PDA ligands in 1 and 2, but discrete and coexist with [Co(H2O)2(PDO)2]2+ metal–organic components in 3. 4 featured [α − Mo8O26]4− anions bi–supported by two [Co(H2O)(PDA)2]2+ metal–organic fragments. The introduction of metal–organic complexes of metal/PDO or PDA improved the light absorption, conductivity and electrochemical active surface area of these hybrid compounds. Consequently, compounds 1–4 as photocatalysts showed photocatalytic activity for degradation of organic dyes with good recyclability and stability at least 3 cycles. The possible photocatalytic degradation mechanism was discussed. Additionally, compounds 1–4 employed as electrode materials demonstrated good capacitive performances, especially 4 with the specific capacitance of 1385.3F g−1 at the current density of 1 A/g.

Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
