Band offsets of n-type electron-selective contacts on cuprous oxide (Cu2O) for photovoltaics

Fabrication of hollow metal oxide nanocrystals by etching cuprous oxide with metal(II) ions: approach to the essential driving force.

Hollow metal oxide nanocrystals were prepared by etching cuprous oxide with metal ions and were applied as photoelectrodes. As a hard template, polyvinylpyrrolidone stabilized cuprous oxide (PVP-Cu2O) and non-stabilized cuprous oxide (nPVP-Cu2O) were synthesized by a precipitation method. Hollow iron oxide and cobalt oxide nanocrystals with a truncated octahedral morphology were fabricated by a...

Synthesis of cuprous oxide nanocomposite electrodes by room-temperature chemical partial reduction.

We demonstrate a template-free synthetic approach for the preparation of a highly conductive Cu/Cu(2)O nanocomposite electrode by a chemical reduction process. Cu(2)O octahedra were prepared through chemical dehydrogenation of as-synthesized Cu(OH)(2) nanowire precursors. To provide a sufficiently electron-conducting network, the Cu(2)O particles were transformed into Cu/Cu(2)O nanocomposites b...

Preparation of Cuprous Oxide Mesoporous Spheres with Different Pore Sizes for Non-Enzymatic Glucose Detection

Mass transfer plays a significant role in a sensor's performance, because the substrate can be detected only when it contacts with the active catalytic surface. In this work, cuprous oxide mesoporous nanospheres (Cu₂O MPNS) with different pore size distributions are fabricated and applied as electrocatalysts for glucose detection. The small pore Cu₂O (SP-Cu₂O, mean pore size of 5.3 nm) and larg...

Morphology effect on antibacterial activity of cuprous oxide.

A glycine-mediated mixed-solvothermal approach has been proposed for the synthesis of novel Cu(2)O structures with different morphologies and the morphology effect on the antibacterial activity of the obtained Cu(2)O crystals has been studied, confirming that the obtained Cu(2)O crystals all show good antibacterial effects and that with the morphology of the Cu(2)O crystals changing from cubic ...
