Integrated carbon capture and utilisation (ICCU) is an emerging technology for simultaneous CO2 adsorption conversion into value-added products. This provides a more sustainable approach compared to storage. Dual-functional materials (DFMs) that couple sorbents (e.g. CaO) catalysts Ni) enable direct of sorbed reactions like dry reforming methane (DRM). However, the potential interactions between sorbent catalyst components within DFMs may induce distinct mechanisms individual materials. Elucidating these synergies interfacial phenomena vital guiding rational design DFMs. article investigates respective roles Ni/SiO2 sol–gel synthesised CaO in integrated via (ICCU-DRM) using decoupling approach. Through decoupled reactor experiments, it found activates react with deposits from CH4 decomposition, achieving maximal CO H2 yields 43.41 mmol g−1 46.78 as well 87.2 % at 650 °C. Characterisation shows coke would encapsulate Ni nanoparticles be active Boudouard reaction, indicating sufficient catalyst-sorbent contact necessary spillover. In-situ DRIFTS reveals no obvious CH4-CaCO3 reaction occurs, chemisorption on enables reverse which further verified by DFT calculations. The findings elucidate dependent synergistic CaO/CaCO3 ICCU-DRM, highlight importance catalyst-adsorbent optimising dual-functional

A combined approach for CO2 capture and photoreduction provides a comprehensive solution to address exhaust emissions. This study aims develop hybrid system integrating membrane contactor photocatalytic technology conversion formic acid by optimizing the synthesis of ZnO-ZnS heterojunction photocatalysts through controlled variations in precursor concentrations calcination temperatures. The catalysts are characterized assess their structural optical properties, activity, stability reaction kinetics. Additionally, performance is also tested using model gas composition that simulates power plant emission with UV or visible light serving as energy source. synthesized exhibit diffraction patterns consistent standard references, measured band gap interval 3.06-3.13 eV. Among three most effective catalysts, labeled Z1 (ZnO:ZnS ratio 1:2 at 400 °C), Z2 1:1 Z4 500 yields were 0.643, 0.554, 0.626 mmol/(L gcat h), respectively. highest yield, 0.936 gcat), was achieved under low feed concentration (15 vol%). Furthermore, LED irradiation, catalyst produced yield 0.394 gcat) after 4 h, demonstrating higher selectivity production. Electrochemical impedance spectroscopy (EIS) analysis shows exhibits lower resistance, enhancing charge transfer efficiency. Scanning electron microscopy (SEM) reveals nanorod-like ZnO globular ZnS structures ranging from 50 100 nm, while high-resolution transmission (HRTEM) confirms presence patterns. After h test, XRD confirmed peaks remained intact, indicating stability. Ultimately, optimized demonstrate promising efficiency selective light, offering viable reduction advanced membrane-photocatalytic technology.
