Releasing the Bubbles: Nanotopographical Electrocatalyst Design for Efficient Photoelectrochemical Hydrogen Production in Microgravity Environment.

Although the overall absorption properties of the photoelectrodes remain similar, the IMPS measurements reveal quite significant differences between the samples (Figure S3 , Supporting Information): the highest charge recombination rate constants ( k rec ) is observed for the 252 nm PVD sample, followed by the 252 nm PED photoelectrode (Figure S3a , Supporting Information).
