Harnessing Visible Light for CO Conversion: The Role of Highly Reduced Phosphomolybdate Crystals as Powerful Photocatalysts.

Heterogeneous photocatalysts, characterized by well-defined atomic structures and the capacity for rapid, directional electron transfer, are pivotal in the exploration and development of highly efficient systems for visible-light-driven diluted CO reduction. Herein, we constructed highly reduced phosphomolybdates crystalline materials - to help this process, with the formula of [Co(CNH)][Co(CNH)(HO)][Co(HPMoO)]·8HO (), [Ni(CNH)(HO)][Ni(CNH)][Ni(HO)][Ni(HPMoO)]·3HO·2CHOH (), and [Zn(CNH)][Zn(CNH)][Zn(CNH)(HO)][Zn(HPMoO)] () [CNH = 2-(1H-pyrazol-3-yl)pyridine]. Specifically, catalyst demonstrated a CO production rate of 3276.

Small Conjugated Organic Ligand-Modified Polyoxometalate-Based Hybrid Materials for Boosting Photocatalytic CO Reduction.

Photocatalytic carbon dioxide (CO) reduction to value-added chemicals is a multielectron transfer process, and the crucial step is the synthesis of photocatalysts. The introduction of small conjugated organic ligands can make the catalytic active site of the compound easier to be exposed in the reaction system and fully contact with the substrate, accelerating the photocatalytic reaction process. In this paper, we synthesized two isomorphic compounds, namely, {[Co(mtrz)·(HO)]·[SiWO]}·6HO () and {[Ni(mtrz)·(HO)]·[SiWO]}·6HO () (mtrz = 1-methyl-1,2,4-triazole).

As for compound , the main structure is composed of {CoO} octahedra connected by edge-sharing to form a two-dimensional layer, on which {ZnO} and {SO} tetrahedra are supported.

Efficient Visible-Light-Driven Hydrogen Production over Cu-Modified Polyoxotungstate Hybrids.

Hydrogen energy is a renewable and clean source, which makes a great difference in future sustainable energy systems. Visible-light-driven photocatalysis reaction involves harnessing the abundance of sunlight for hydrogen production among many catalytic technologies. However, the fabrication of photocatalysts that have distinctive performance in visible light is still the primary challenge.

Two 1D Anderson-Type Polyoxometalate-Based Metal-Organic Complexes as Bifunctional Heterogeneous Catalysts for CO Photoreduction and Sulfur Oxidation.

Sulfur oxides from the combustion of petrol and excessive emissions of carbon dioxide (CO) are currently the main causes of environmental pollution. Considerable interest has been paid to solving the challenge, and catalytic reactions seem to be the desired choice. Due to the high density of Lewis acid active sites, polyoxometalates are considered to be the ideal choice for these catalytic reactions.

Construction and characterization of monoclonal antibodies specific for the R transactivator 185 of Epstein-Barr virus.

Epstein-Barr virus (EBV) has been implicated in the pathogenesis of several human malignancies including B lymphomas and nasopharyngeal carcinoma. The EBV R transactivator (Rta) has been found to play essential roles in stimulating a lytic cycle and viral gene expression. Recently, it was shown that ELISA detecting serum IgG-Rta(150+185) (two internal fragments of Rta) levels may be useful as a serological parameter to assist in the diagnosis of nasopharyngeal carcinoma.

Association of transforming growth factor-beta1 gene polymorphisms with genetic susceptibility to nasopharyngeal carcinoma.

Background: Nasopharyngeal cancer (NPC) is multifactorial, and the genetic background may be a crucial etiologic factor. Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine, it promotes tumor growth and metastasis in later stages of phase of cancer development. Variations in the DNA sequence in the TGF-beta1 gene may lead to altered TGF-beta1 production and/or activity, and so this can modulate an individual's susceptibility to NPC.
