This is a review paper about perovskite oxides doped with transient metal ions for photocatalytic water splitting under visible light irradiation. 3 runs of revision, and 9 reviewers in totally...I cannot believe we survive. "Transition-metal-Doped Perovskite Oxide Materials: A Key Pathway for Photocatalytic Water Splitting Under Visible-light Irradiation", ACS Catalysis, DOI: 10.1021/acscatal.5c05792.

The local mass transfer on particulate photocatalyst has been carefully tailored for promoting H2O2 generation. A solar energy conversion efficiency of > 1% was achieved, along with scalable demonstration. Three runs of revision, and ~100 pages of response letter. This has been a formidable way!
