Photo/electrocatalysts facilitate the reduction of CO₂ into valuable chemicals and fuels offering a promising approach for mitigating climate change and promoting sustainable carbon utilization. In this study, Tris-porphyrin based metal organic framework, namely TP@AlTrisMOF, was successfully synthesized and characterized for its photo/electrocatalytic CO₂ reduction capabilities. Energy dispersive x-ray spectroscopy (EDX) and X-ray photo electron spectroscopy (XPS) confirmed the elemental composition and bonding environments within TP@AlTrisMOF. Scanning electron microscopy (SEM) revealed a layered, needlelike morphology aggregated into a dense, porous network. Fluorescence emission spectra of TP@AlTrisMOF showed red shift with longer wavelength while TP@AlTrisMOF displayed a band gap of 1.81 eV. Electrochemical characterization further highlighted the outstanding performance of TP@AlTrisMOF; chronoamperometry (6 h) confirmed its exceptional stability. In electrochemical impedance spectroscopy (EIS), the charge transfer resistance (Rct) decreased from 128.5 to 3.55 after the reduction process, indicating a significant enhancement in conductivity, and mott-schottky analysis offered valuable insights into the fermi level (−0.3 eV) and valence band structure. Photocatalytic CO₂ reduction experiments showed successful conversion into formic acid, as verified by GC–MS analyses. Notably, the TP@AlTrisMOF maintained structural integrity and functional performance after reaction cycles, demonstrating its recyclability. The mechanistic study revealed that both Al–O clusters and nitrogen-based sites played critical roles in the activation and reduction of CO₂ through photo/electro driven pathways. These findings suggest that TP@AlTrisMOF is a promising and robust candidate for sustainable CO₂ conversion applications.
