In order to carbonize o-phenylenediamine with CO2, an effective approach was used with UV light irradiation by Sn(IV) doping DFNS (SnD) supported CdSnO3 as a catalyst (CdSnO3/SnD). In this catalyst, SnD with the ratios of Si/Sn in the range of 6 to 50 were obtained using the Direct Hydrothermal Synthesis (DHS), and the nanoparticles of CdSnO3 on the surfaces of SnD were reduced in situ. Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Energy Dispersive Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) were utilized for characterizing CdSnO3/SnD. It was found that CdSnO3/SnD nanostructures could be used for synthesizing o-phenylenediamines due to their effective and novel catalytic behavior through the reaction between o-phenylenediamines and CO2.

CdSnO3/SnD NPs 作为邻苯二胺与 CO2 羰基化的纳米催化剂

为了用 CO2 碳化邻苯二胺，一种有效的方法是通过 Sn(IV) 掺杂的 DFNS (SnD) 负载的 CdSnO3 作为催化剂 (CdSnO3/SnD) 进行紫外光照射。在该催化剂中，使用直接水热合成法 (DHS) 获得了 Si/Sn 比在 6 至 50 范围内的 SnD，并原位还原了 SnD 表面上的 CdSnO3 纳米颗粒。扫描电子显微镜 (SEM)、X 射线衍射 (XRD)、傅里叶变换红外光谱 (FT-IR)、X 射线能量色散光谱 (EDS) 和透射电子显微镜 (TEM) 用于表征 CdSnO3/SnD。研究发现，CdSnO3/SnD 纳米结构可用于合成邻苯二胺，因为它们通过邻苯二胺与 CO2 之间的反应具有有效且新颖的催化行为。
