Interfacial Engineering over Pt-Calcium Ferrite/2D Carbon Nitride Nanosheet p-n Heterojunctions for Superior Photocatalytic Properties.

The present study discloses the fabrication of efficient p-n heterojunctions using n-type polymeric bulk carbon nitride (b-CN, = 2.7 eV) or exfoliated nanosheets of carbon nitride (NSCN, = 2.9 eV) with p-type spinel ferrite CaFeO (CFO, = 1.

Silver nanoparticle-decorated NiFeO/CuWO heterostructure electrocatalyst for oxygen evolution reactions.

In this work, Ag nanoparticles decorated with NiFeO/CuWO heterostructure were synthesized using the step-wise precipitation method. The influence of varying Ag loading on the NiFeO/CuWO heterostructure and its electrochemical OER performance was extensively studied in 1 M KOH electrolyte. The obtained LSV profile was analyzed to determine the overpotential, Tafel slope, and onset potential.
