چکیده
High photoelectrochemical water oxidation efficiency can be achieved through an efficient photogenerated holes transfer pathway. Constructing a photoanode semiconductor heterojunction with close interface contact is effective tactic to improve the of carrier separation. Here, we reported novel p-n junction Ti:Fe2O3/Cu2O (n-Ti:Fe2O3 and p-Cu2O), Cu2O being obtained by in situ reduction CuAl-LDH (layered double hydroxides). The exhibits high photocurrent density reaching 1.35 mA/cm2 at 1.23 V vs. RHE about 1.67 50 times higher than Ti:Fe2O3 α-Fe2O3 photoanode, respectively. enhanced PEC activity for n-Ti:Fe2O3/p-Cu2O photoelectrode due remarkable surface charge separation (ηsurface 85%) bulk (ηbulk 72%) formed tight reduction. Moreover, as cocatalyst, protect its stability certain extent. This study provides insight into manufacturing potential layered hydroxides designing highly active photoanodes field oxidation.

Two highly efficient protocols for the production of bis-coumarins under solvent-free conditions have been introduced. The reaction of 4-hydroxycoumarin (2 eq.) with arylaldehydes (1 eq.) using phthalimide-N-sulfonic acid (PhtSA) or isatin-N-sulfonic acid (IsSA), as solid-acid catalysts, afforded the mentioned compounds with good to excellent yields in short times.Briefly, we have introduced tw...
