Can metal oxides be used for hydrogen production using concentrated solar energy?

Abanades, S. Metal oxides applied to thermochemical water-splitting for hydrogen production using concentrated solar energy. Chem. Eng. 2019, 3, 63, DOI: 10.3390/chemengineering3030063 Linic, S.; Christopher, P.; Ingram, D. B. Plasmonic-metal nanostructures for efficient conversion of solar to chemical energy. Nat.

Can solar energy be used to produce H2?

It is clear that only using solar energy as the energy input can realize appreciable or considerable H 2 production with both high STF efficiency and durability, representing sustainable and effective routes to produce H 2 by utilizing renewable energy.

What is the maximum STH efficiencies of solar H2 production technologies?

Many studies and reviews have reported the theoretical maximum STH efficiencies of solar H 2 production technologies. (10,22,124−126) For PC water splitting, the minimum photon energy necessary for driving water splitting is 1.23 eV theoretically over single-semiconductor photocatalysts.

Can a solar furnace produce iron oxide?

Charvin et al. reported a laboratory-scale two-step iron oxide-based cycle for solar H 2 production along with a detailed thermodynamic analysis. (85) For the endothermic reduction reaction, nearly 100% yield of FeO was obtained within 2 min by a solar furnace at 1700 °C and 0.1 bar.

What are the different approaches to solar H2 production?

This Focus Review discusses the different approaches to solar H 2 production, including PC water splitting, PEC water splitting, PV-EC water splitting, STC water splitting cycle, PTC H 2 production, and PB H 2 production, and introduces the recent cutting-edge achievements in these different routes.

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 ).
