Summary: This study presents an energy efficient MEA-based electrochemical CO2 capture process, addressing the energy-intensive, low current density, slow reaction rate, and amine degradation challenges in electrochemically-mediated amine regeneration (EMAR) technology for commercial applications. A comprehensive investigation of the redox reactions of copper ions and the influence of other mediums is conducted. Additionally, the amine oxidative degradation in EMAR is discussed from the perspective of solution electrochemical mechanism. The results show that suitable current density and disturbance can enhance the circulation performance of the system, and the regeneration energy consumption is competitive compared to traditional CO2 chemical absorption methods.

Summary: A CO2 regeneration test rig was built to recover waste heat from stripped gas in carbon capture process, and five ceramic membrane heat exchangers (CMHEs) and two stainless-steel heat exchangers (SSHEs) were experimentally investigated. The experimental results showed that CMHEs had higher reboiler duty reduction than SSHEs, and Config-B, Config-C, and Config-E could reduce the reboiler duty by around 22%. Economic analysis revealed that Config-D achieved the maximum CO2 capture cost saving of $4.41/t-CO2. The development of membrane technology is expected to further promote cost savings.

Summary: This study presents a microwave-accelerated regeneration system, MARS, for efficient carbon capture from the ambient air. The experiments showed that the CO2 desorption rate from the chemisorbents was improved with increasing microwave output, primarily due to the highly polarized carbamate. The instant and selective delivery of microwave energy to the targeted C-N bonds at room temperature makes MARS particularly advantageous for energy-efficient direct air capture. The experimental results also demonstrated a good working capacity and promising performance of the MARS-DAC process.

Summary: Around two-thirds of CO2 emissions from the cement industry come from calcite decomposition in the calciner, which can be significantly reduced by electrifying the process. A process simulation model using Aspen Plus was used to study the possibility of this method. The results showed that CO2 emissions could be reduced by up to 78%. The total energy required varied depending on the gas recycling scenario, ranging from 137 MW to 154 MW.

Summary: Acyclic diamino carbenes (ADCs) are interesting alternatives to N-heterocyclic carbenes, offering greater synthetic accessibility and properties such as increased sigma-donation and structural flexibility. The reaction of primary diamines with isocyanide gold chlorides resulted in dimeric gold complexes, while secondary diamines led to the expected bis-ADC gold complexes. Density functional theory calculations showed that primary diamines have higher reaction barriers and slower reaction rates compared to secondary diamines.

Summary: The bottom-up synthesis of plasmonic NHC@CuNPs from common starting reagents, via the formation of the synthetically accessible NHC-Cu(I)-Br complex and its reduction by NH3·BH3 is reported. The resulting NHC@CuNPs have been characterized in detail by XPS, TEM and NMR spectroscopy. The stability of NHC@CuNPs was investigated under both inert and ambient conditions using UV-Vis analysis. While the NHC@CuNPs are stable under inert conditions for an extended period of time, the NPs oxidize under air to form CuxO with concomitant release of the stabilizing NHC ligand.
