Oxygen-deficient solar power generation system

Do algal cell bioelectrogenic reactors self-regulate oxygen levels during artificial photosynthesis?

Moreover, the algal cell bioelectrogenic reactors self-regulate the oxygen level during artificial photosynthesis; therefore, the resulting hydrogen fuel is available for direct feed into a commercial fuel cell without the need of separation or purification.

How does oxygen-deficient black zirconia (ZrO 2x) affect solar light absorption?

In conclusions, oxygen-deficient black zirconia (ZrO 2−x) was prepared via the magnesiothermic reduction in H 2 /Ar atmosphere, which resulted in a drastic increment in solar light absorption and band gap decrement (to 1.52 from 5.09 eV for white ZrO 2 ).

Does BZ have oxygen deficiency?

The presence of oxygen deficiency in BZ was further evidenced by thermogravimetric analysis ( Supplementary Figure S6) in the presence of oxygen, which shows a weight increment after ~150 °C, indicating the oxygen uptake.

What happens if the activity of O2 evolution is poor?

In particular, if the activity of O 2 evolution on the photoanode surface is poor, the competing H 2 O 2 evolution reaction will consume the majority of photogenerated holes, significantly increasing the H 2 O 2 evolution efficiency.

Is H2O2 a viable end product for solar-to-fuel conversion?

It is not only a potentially rewarding strategy to generate H 2 O 2 as an end product because of its economic benefit but also an efficient approach to achieve high solar-to-fuel conversion rates using H 2 O 2 as an intermediate by a two-electron pathway.
