Non-metal fluorine doping in Ruddlesden-Popper perovskite oxide enables high-efficiency photocatalytic water splitting for hydrogen production

Xiao Han et al.

Summary: In this study, a non-metal fluorine (F-) doping strategy was utilized to enhance the photocatalytic activity of Ruddlesden-Popper Sr2TiO4 perovskites for H-2 evolution reaction (HER). By optimizing the F- doping amount, the highest H2 generation rate was achieved by Sr2TiO3.97F0.03, which showed a 44% enhancement compared to Sr2TiO4. The improved photocatalytic activity of Sr2TiO3.97F0.03 can be attributed to the effects of F- doping on surface oxygen vacancies, charge carrier recombination, conduction band position, band gap energy, particle size, and specific surface area.

The Discrepancy in Oxygen Evolution Reaction Catalyst Lifetime Explained: RDE vs MEA-Dynamicity within the Catalyst Layer Matters

Mohammad Fathi Tovini et al.

Summary: This study reveals the discrepancy in lifetime of oxygen evolution reaction (OER) catalysts between rotating disk electrode (RDE) measurements and membrane electrode assembly (MEA) in an electrolyzer, due to the accumulation of microscopic oxygen bubbles in the electro-catalyst layer pores. This accumulation is more significant in RDE measurements, leading to rapid performance deterioration by shielding almost all catalyst active sites with gas bubbles, which also induces irreversible catalyst degradation.
