Description:Abstract:\n\nA key interest in chemical synthesis research is t
 he conversion of less desirable resources to value-added products.[1] Hydr
 ogen peroxide is an increasingly valuable feedstock with applications as a
 n antiseptic agent and wastewater treatment aid\, a strong oxidant for che
 mical synthesis\, and even an energy-dense catholyte for fuel cell applica
 tions.[2\,3] Current synthesis methods for hydrogen peroxide require elect
 rolytic conditions\, toxic or rare transition metal catalysts\, or high-pu
 rity aqueous and organic solvents to avoid catalyst poisoning or degradati
 on [2\,4]\, making these approaches energy-intensive and reliant on limite
 d resources. Photocatalytic methods – which utilize light irradiation an
 d a photocatalyst to facilitate chemical reactions – have been explored 
 recently to achieve more sustainable hydrogen peroxide production and\, in
  some cases\, can use extremely abundant seawater as an effective solvent.
 [3-7] This paper by Ren and co-workers demonstrates the formation of hydro
 gen peroxide from real seawater using a single-atom photocatalyst (SAPC) c
 omposed of atomically dispersed manganese on a carbon-nitride scaffold.[7]
  In this seminar\, I will discuss the evidence and findings of the paper\,
  and the implications of this research in the larger context of photocatal
 ytic hydrogen peroxide synthesis.\n\n&nbsp\;\n\nReferences:  \n\n[1] Wang
