Controllable Synthesis, Formation Mechanism, and Photocatalytic Activity of Tellurium with Various Nanostructures

Telluriums (Te) with various nanostructures, including particles, wires, and sheets, are controllably synthesized by adjusting the content of polyvinylpyrrolidone (PVP) in a facile solvothermal reaction. Te nanostructures all have complete grain sizes with excellent crystallinity and mesopore struct...

Te nanostructures all have complete grain sizes with excellent crystallinity and mesopore structures. Further, the formation mechanisms of Te nanostructures are proposed to be that the primary nuclei of Te are released from the reduction of TeO<sub<3</sub<<sup<2−</sup< using N<sub<2</sub<H<sub<4</sub<·H<sub<2</sub<O, and then grow into various nanostructures depending on the different content of PVP. These nanostructures of Te all exhibit the photocatalytic activities for the degradation of MB and H<sub<2</sub< production under visible light irradiation, especially Te nanosheets, which have the highest efficiencies of degradation (99.8%) and mineralization (65.5%) at 120 min. In addition, compared with pure Te nanosheets, the rate of H<sub<2</sub< production increases from 412 to 795 μmol∙h<sup<−1</sup<∙g<sup<−1</sup< after the introduction of Pt, which increases the output by nearly two times. The above investigations indicate that Te with various nanostructures is a potential photocatalyst in the field of degradation of organic pollutants and H<sub<2</sub< fuel cells.

abstract	Telluriums (Te) with various nanostructures, including particles, wires, and sheets, are controllably synthesized by adjusting the content of polyvinylpyrrolidone (PVP) in a facile solvothermal reaction. Te nanostructures all have complete grain sizes with excellent crystallinity and mesopore structures. Further, the formation mechanisms of Te nanostructures are proposed to be that the primary nuclei of Te are released from the reduction of TeO<sub<3</sub<<sup<2−</sup< using N<sub<2</sub<H<sub<4</sub<·H<sub<2</sub<O, and then grow into various nanostructures depending on the different content of PVP. These nanostructures of Te all exhibit the photocatalytic activities for the degradation of MB and H<sub<2</sub< production under visible light irradiation, especially Te nanosheets, which have the highest efficiencies of degradation (99.8%) and mineralization (65.5%) at 120 min. In addition, compared with pure Te nanosheets, the rate of H<sub<2</sub< production increases from 412 to 795 μmol∙h<sup<−1</sup<∙g<sup<−1</sup< after the introduction of Pt, which increases the output by nearly two times. The above investigations indicate that Te with various nanostructures is a potential photocatalyst in the field of degradation of organic pollutants and H<sub<2</sub< fuel cells.

Te nanostructures all have complete grain sizes with excellent crystallinity and mesopore structures. Further, the formation mechanisms of Te nanostructures are proposed to be that the primary nuclei of Te are released from the reduction of TeO<sub<3</sub<<sup<2−</sup< using N<sub<2</sub<H<sub<4</sub<·H<sub<2</sub<O, and then grow into various nanostructures depending on the different content of PVP. These nanostructures of Te all exhibit the photocatalytic activities for the degradation of MB and H<sub<2</sub< production under visible light irradiation, especially Te nanosheets, which have the highest efficiencies of degradation (99.8%) and mineralization (65.5%) at 120 min. In addition, compared with pure Te nanosheets, the rate of H<sub<2</sub< production increases from 412 to 795 μmol∙h<sup<−1</sup<∙g<sup<−1</sup< after the introduction of Pt, which increases the output by nearly two times. The above investigations indicate that Te with various nanostructures is a potential photocatalyst in the field of degradation of organic pollutants and H<sub<2</sub< fuel cells.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">tellurium</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">various
