Synthesis of Bi nanoparticles supported on activated carbon for efficient photocatalytic degradation of high concentration Rhodamine B
2020
Bismuth (Bi) micro, nanoparticles are an emerging non-noble metal catalyst, but they are prone to agglomeration due to the large surface energy, which weakens its function and limits its application. Bi nanoparticles were immobilised on activated carbon by the impregnation reduction method to prevent the agglomeration. The prepared material exhibited enhanced photocatalytic efficiency compared to Bi nanoparticles alone. The origin of photocatalytic efficiency enhancement was investigated. It was attributed to the large specific surface area of the composite and more exposed active sites. This research proposes a new strategy for the photocatalytic application of Bi nanoparticles.
