a Comparison of current density–potential curves of LDH/Ni/eu@nfOP for five consecutive days immersed in 1 M NaOH electrolyte (pH 13.6) under AM 1.5 G illumination (100 mW cm−2) to check the chemical stability. b Comparison of normalized current density–time curves of LDH/Ni/eu@nfOP for water oxidation and sulfite oxidation at 1.3 V vs. RHE. For sulfite oxidation, 0.4 M Na2SO3 is added. c Comparison of normalized current density–time curves of LDH/Ni/eu@nfOP under AM 1.5 G illumination (UV + Vis, 100 mW cm−2) and visible light (with 420 nm cut-off filter, 100 mW cm−2). d Comparison of normalized efficiency of PBDB-T:ITIC-based OPVs under AM 1.5 G illumination (UV + Vis) and visible light (with 420 nm cut-off filter).
