Enhancing CO₂ Capture and Conversion to Formic Acid via a Membrane-Photocatalytic Hybrid System with ZnO-ZnS Heterojunction Catalyst.

ABSTRACT: A combined approach for CO₂ capture and photoreduction provides a comprehensive solution to address exhaust emissions. This study aims to develop a hybrid system integrating membrane contactor and photocatalytic technology for CO₂ conversion to formic acid by optimizing the synthesis of ZnO-ZnS heterojunction photocatalysts through controlled variations in precursor concentrations and calcination temperatures. The catalysts are characterized to assess their structural and optical properties, photocatalytic activity, stability and reaction kinetics. Additionally, the photocatalytic performance is also tested using a model gas composition that simulates power plant emission with UV or visible light serving as the energy source. The synthesized ZnO-ZnS catalysts exhibit
