Research topics from publications: Heterointerface Connection with Multiple Hydrogen-Bonding in Z-Scheme Heterojunction SiW9Co3@UiO-67-NH2 Deciding High Stability and Photocatalytic CO2 Reduction Performance; Phenanthraquinone modified carbon quantum dots covalent-grafted onto Cu-MOF for photocatalytic CO2 reduction: Construction of dual-active sites and parallel charge channels based on the cooperation between photoexcitation and electron-entrap; Matched micro-geometrical configuration leading to hetero-interfacial intimate contact of MoS2@UiO-66-NH2 Z-scheme heterojunction for efficient photocatalytic CO2 reduction; Electronic-supply crystal facet guiding enhancement of interfacial charge transfer in homologous covalent heterojunction NiO/Ni-BDC for efficient photocatalytic CO2 reduction. Representative work: Merging metal–organic frameworks (MOFs) and polyoxometalates (POMs) into heterogeneous heterojunction photocatalysts through in situ encapsulation is an effective approach to suppress the leachability of POMs and enhance their electron supply. The heterointerfacial connection in POMs@MOFs directly determines the performance of stability and charge separation, and the suited interaction between MOFs and POMs for POMs@MOFs heterojunctions photocatalyst is of vital importance. Here, a distinctive Keggin-type POM [(n-C4H9)N]10[SiW9Co3 (H2O)3O37]·17H2O (SiW9Co3) with near-total visible region absorption, narrow band gap of 2.23 eV, and powerful electron supply activity was prepared and tightly im
