Photocatalytic Degradation of Rhodamine B Dye with Rhodium @Graphitic Carbon Nitride Nanosheets as Effective catalyst

In this work, a novel light-active Rh catalyst was prepared through decorating graphitic carbon nitride nanosheets with Rhodium nanoparticles, denoted as g-C۳N۴@Rh, and was employed for the degradation of Rhodamine B (RB) dye under visible-light irradiation. Rh nanoparticles are crucial in facilitating the efficient separation of photogenerated charges and exhibiting high absorption in the visible-light region. More surprisingly, Rh/ g-C۳N۴ does surpass by up to ۵ times the behavior reached with bare g-C۳N۴. The experimental findings indicated that the optimal degradation of Rhodamine B dye occurred after ۶۰ minutes when using a concentration of ۲۰ mg L-¹ Rhodamine B and a concentration of ۰.۰۵ g L-۱ Rh/g-C۳N۴, under a pH of ۴.
