From: Direct ammonia and dihydroxyacetone production in an unbiased photoelectrochemical cell
a, b SEM images of (a) TiO2 and (b) Ru-Bi2O3/TiO2. c, d TEM and HRTEM images of Ru-Bi2O3/TiO2. e EDS mappings of Ru-Bi2O3/TiO2. Inset shows the related TEM image. f J-V curves of TiO2 and Ru-Bi2O3/TiO2 in 0.5 M Na2SO4 with or without 0.1 M glycerol (pH = 2) under AM 1.5 G illumination. g FEs of TiO2 and Ru-Bi2O3/TiO2 at 0.6 VRHE. h DHA selectivities and yields over TiO2 and Ru-Bi2O3/TiO2 at various potentials. i FEs of Ru-Bi2O3/TiO2 at various potentials. The error bar represents the standard deviation of values calculated from three independent samples. j I-t curve and FEs over Ru-Bi2O3/TiO2 at 1.2 VRHE for 20 h under AM 1.5 G illumination.
