Hematite Photoanodes for Solar Water Splitting: A Detailed Spectroelectrochemical Analysis on the pH-Dependent Performance

Nestor Guijarro Carratala, Florian Le Formal, Yongpeng Liu, Florent Alexandre Boudoire

The effect of the electrolyte pH on the performance of metal oxide photoanodes for solar water oxidation has not been fully resolved, and contrasting views have been presented in recent reports. Herein, a comprehensive set of spectroelectrochemical techniq ...

Effects of Se Incorporation in La5Ti2CuS5O7 by Annealing on Physical Properties and Photocatalytic H-2 Evolution Activity

Takashi Hisatomi, Swarnava Nandy

Oxysulfoselenide semiconductor photocatalysts absorb light at longer wavelengths than the corresponding oxysulfides. However, the synthesis of oxysulfoselenides is challenging due to excessive particle growth and the limited availability of metal selenide ...

A Step toward Economically Viable Solar Fuel Production

Kevin Sivula

Recently in Joule, Zhang, Li, and colleagues reported a new benchmark in photocatalytic overall water splitting. By optimizing the co-catalysts and redox mediator between the light absorbers in a two-step heterogeneous photosystem, the authors reached an a ...

Continuum-scale Modeling of Solar Water-splitting Devices

Sophia Haussener

In this chapter, we discuss the methodology beyond the mathematical modeling of solar water-splitting cells. In particular, we focus on the governing mathematical equations and relationships at the continuum level for mass, energy, light, and species trans ...
