Can photoanode drive iodide oxidation reaction?

The iodide oxidation reaction (IOR) is a promising alternative to OER due to its low thermodynamic energy and two-electron-involved fast reaction kinetics. Herein, we report a high-performance catalyst-modified Sb 2 S 3 photoanode to drive IOR.

How to choose oxidation and reduction reactions for solar electrolysis?

For future practical solar electrolysis, oxidation and reduction reactions should be chosen based on their economic value and feasibility. Solar-driven electrolysis can produce value-added chemicals through less energy-intensive processes.

Why is oxidation kinetics important for photoanodes?

This is particularly important for photoanodes, where the sluggish oxidation reaction kinetics can lead to rapid build-up of charges at the organic semiconductor–electrocatalyst interface that decrease efficiency and lead to degradation of the organic semiconductor 10, 14.

Does atomic layer deposited tunnel oxide stabilize silicon photoanodes for water oxidation?

Chen, Y. W. et al. Atomic layer-deposited tunnel oxide stabilizes silicon photoanodes for water oxidation. Nat. Mater. 10, 539–544 (2011). Hu, S. et al. Amorphous TiO 2 coatings stabilize Si, GaAs, and GaP photoanodes for efficient water oxidation. Science 344, 1005–1009 (2014).

Can photovoltaic-electrochemical (PV–EC) oxidation be used to produce hydrogen?

Our work presents a clear and viable approach to ecofriendly hydrogen production based on an unprecedented combination of a photovoltaic–electrochemical (PV–EC) system and an IOR as an alternative oxidation reaction. MoS 2 was deposited on substrates using the ALD process.

Do photophysical processes influence water oxidation reactions?

Varying temperature measurements reveal that the photophysical processes and the subsequent chemical steps exhibit mutual influence on each other in photoelectrochemical water oxidation reactions.
