Herein, two porphyrins with bismuth metal incorporated in the porphyrinic core were synthesized having peripheral carboxyl and hydroxyl functional groups. The successful synthesis of free base porphyrin and their bismuth-integrated metalloporphyrins was identified using ¹H NMR spectroscopy, UV-visible and Fourier transform infrared (FT-IR). Further, these bismuth porphyrins complexes were doped with thermally reduced graphene oxide (TRGO) via simple solvothermal techniques. The intrinsic characteristics of prepared metalloporphyrins-based reduced graphene oxide nanocomposites were examined by using various spectroscopic techniques like, photo-physical properties (UV-Visible spectroscopy and Fluorescence spectroscopy), Fourier transform infrared (FT-IR), powdered X-ray diffraction (P-XRD) patterns, FE-SEM and EDX analysis. At last, the photocatalytic properties of nanocomposites were demonstrated by photocatalytic degradation of industrial pollutant rhodamine B (Rh-b) on irradiation of visible light. The catalytic efficiency of RGO-Bi-P1 and RGO-Bi-P2 came out to be 94.58% and 93.26%, respectively.

在此，合成了两种在卟啉核中掺入金属铋的卟啉，其具有外围羧基和羟基官能团。^使用1 H NMR 光谱、紫外-可见光和傅里叶变换红外 (FT-IR)鉴定了游离碱卟啉及其铋集成金属卟啉的成功合成。此外，这些铋卟啉配合物通过简单的溶剂热技术掺杂有热还原氧化石墨烯（TRGO）。通过使用各种光谱技术，如光物理性质（紫外-可见光谱和荧光光谱）、傅里叶变换红外（FT-IR）、粉末X射线衍射（ P-XRD）图谱、FE-SEM 和 EDX 分析。最后，通过在可见光照射下光催化降解工业污染物罗丹明B（Rh-b），证明了纳米复合材料的光催化性能。RGO-Bi-P1和RGO-Bi-P2的催化效率分别为94.58%和93.26%。
