YTYu TakagiInstitute of Science TokyoMYMasaya YaraKyushu UniversityTTToshiya TanakaTokyo Institute of Technology

Key Points

  • This research aims to improve CO2 reduction activity in molecular photocathodes by introducing an alumina layer.
  • Applied an Al2O3 overlayer to p-type NiO photocathodes.
  • Utilized Ru(II)-based photosensitizing molecular units.
  • Conducted operando transient absorption spectroscopy to analyze charge interactions.
  • Al2O3 significantly enhances CO2 reduction activity under visible light.
  • The alumina layer suppresses charge recombination, increasing photocathode efficiency.

Abstract

Interfacial engineering with an Al2O3 overlayer enhances visible-light-driven CO2 reduction on p-type NiO photocathodes incorporating Ru(II)-based photosensitizing molecular units. Operando transient absorption spectroscopy reveals that Al2O3 suppresses charge recombination between...
