In this paper, a concept of integrated CO2 capture and reverse water–gas shift (ICCrWGS) process was proposed using NH3 as the H2 carrier. The efficiency total thermal energy consumption for conventional rWGS, ICCrWGS (H2-ICCrWGS) (NH3-ICCrWGS), were calculated. conducted over thermally stable Ni/CaZr dual-function materials (DFMs). decomposition, capacity, conversion, CO selectivity addressed at different reaction temperatures, optimal temperature determined to be 650 °C. DFMs exhibited capacity productivity during A carbonate spillover mechanism production in NH3-ICCrWGS situ diffuse reflectance infrared Fourier transform spectroscopy. It found that is produced from bridged bidentate route Ni–CaO interface.

Global warming and climate change require urgent reduction of CO2 emissions. Integrated carbon capture utilisation combined with dry reforming methane (ICCU-DRM) has the potential to mitigate greenhouse gas emissions by capturing converting CH4 into valuable syngas. However, performance stability dual-functional materials (DFMs) are unclear under real-world flue conditions, particularly in presence steam O2. In this study, we elucidated mechanisms a Ni0.05/CaO0.95 DFM various conditions investigated effects O2 on uptake, CO H2 yields cyclic stability. Our approach includes synthesis evaluation using advanced characterisation techniques, such as XRD, in-situ infrared spectroscopy, CH4-TPR, SEM, EXD, FIB-SEM, BET, XPS, gain insights properties behaviour different conditions. The findings show that simulated condition (10.0 % + 6.0 H2O 6.7 O2/N2), there was significant deterioration performance, uptake only 5.7 mmol.g-1, average yield 11 mmol.g-1 6.2 mmol.g-1. While ideal CO2/N2), were 10.7 16.9 23.1 respectively. FIB-SEM XPS analysis highlighted effect during ICCU-DRM. Notably, promoted oxidation Ni, resulting decreased catalytic activity volumetric expansion Ni particles. Furthermore, adsorption, inducing additional CaO component DFM. These synergistic expansions form dense shell surface, hindering internal NiO, thereby diminishing performance.

An integrated CO2 capture and direct methanation (ICCM) system has recently gained significant attention as a promising process to produce value-added chemicals. Compared conventional utilization, ICCM is simplified that directly converts captured without purification at lower thermal inputs. One of the primary limitations deactivation sorbent embedded catalysts after several cycles. In this study, we formulated thermally stable macroporous structured Ni/CaO dual function materials (DFMs) by incorporating Zr stabilizer. The textural properties, porosity, performance, catalytic activity Zr-modified (Ni/CaZr) were assessed. situ DRIFTS was used investigate possible intermediates reactions during ICCM. It found CH4 produced from formate methoxy route on CaO surface CO intermediate Ni surface. Ni/CaZr had improved stability with best capacity (13–14 mmol CO2/g), productivity CH4/g), sorption, desorption kinetics 500 °C. benefit adding for enhanced structures, which mass transport prevented sintering CaO.

Dual functional materials (DFMs) are a promising approach to increase the energy efficiency of carbon capture and utilization by combining both steps into single unit operation. In this Perspective, we analyze challenges opportunities integrated (ICCU) via thermally driven process. We identify three key areas that will facilitate research progress toward industrially viable solutions: (1) selecting appropriate DFM operating conditions; (2) designing characterizing interfacial site cooperativity for CO2 adsorption hydrogenation; (3) establishing standards rigorous comprehensive data reporting.
