A team of Japanese and South Korean researchers has pioneered a way to use seawater to obtain hydrogen peroxide (H2O2) instead of using pure water as a solar fuel. Their paper, “Seawater usable for production and consumption of hydrogen peroxide as a solar fuel,” was published in the May 4 edition of Nature Communications. “It is highly desired to utilize the most earth-abundant seawater instead of precious pure water for the practical use of H2O2 as a solar fuel,” the researchers said in the paper.
