Kobe team’s hematite mesocrystal photocatalyst simultaneously produces hydrogen and hydrogen peroxide

Green Car Congress

Using a hematite photocatalyst, a team led by researchers from Kobe University has succeeded in producing both hydrogen gas and hydrogen peroxide at the same time from sunlight and water. Hydrogen has gained attention as one of the possible next generation energy sources. under 600nm). Mesocrystal technology.

Mathematically-designed graphene has improved electrocatalytic activity for hydrogen production

Green Car Congress

An international research group has improved graphene’s ability to catalyze the hydrogen evolution reaction, which releases hydrogen as a result of passing an electronic current through water. The graphene-based electrocatalyst was then used to enhance the release of hydrogen during electrolysis. Wakisaka, Y. Takahashi, K.

Elemental boron effective photothermocatalyst for the conversion of CO2 for fuels and chemicals

Green Car Congress

Researchers in Japan and China developed an efficient method for CO 2 reduction over elemental boron catalysts in the presence of only water and light irradiation through a photothermocatalytic process. At this temperature it reacts with water, forming hydrogen and boron oxides in situ. —Jinhua Ye.
