6 FAQs about [Oxygen-deficient solar power generation solution]

How do oxygen vacancies affect solar energy utilization?

To be specific, oxygen vacancies induce an intermediate band within the bandgap for harvesting low-energy photons in the visible and near-infrared regions, thereby enabling the full-spectrum solar energy utilization of TVCNMWCA-HEO.

Can solar energy be used to produce hydrogen peroxide?

Nature Communications 15, Article number: 9505 (2024) Cite this article The direct utilization of solar energy for the artificial photosynthesis of hydrogen peroxide (H 2 O 2) provides a reliable approach for producing this high-value green oxidant.

How do oxygen vacancies affect photoelectrochemical and photocatalytic performance?

For metal oxides in general, oxygen vacancies are prevalent defects that can profoundly impact their photoelectrochemical and photocatalytic performance 50. It has been widely proved that oxygen vacancies can effectively enhance visible light absorption by introducing electronic mid-gap states.

Do non-noble metal oxide catalysts drive oxygen evolution in alkaline solution?

Current non-noble metal oxide catalysts developed to drive oxygen evolution in alkaline solution have poor performance in neutral solutions.

Can SGC be used for oxygen evolution in neutral solution?

While the GC-RDE setup allowed us to firmly establish the intrinsic activity and stability of SGC for oxygen evolution in neutral solution, we also evaluated the potential of using SGC towards practical applications. To do this we drop-casted the catalyst ink on a carbon paper electrode and measured the performance in a three-electrode setup.

How effective is a GaInP solar cell for reducing CO2?

Paring the SGC anode and anodized silver (a-Ag) cathode and coupling the electrolysis cell with triple-junction GaInP/GaInAs/Ge solar cell in a BPM-free device, the integrated device achieved the average solar-to-CO efficiency of 13.9%, setting a record of STF for sunlight-driven CO 2 reduction.
