Summary: Carbon nanotubes (CNTs) possess exceptional mechanical, electrical, and thermal properties. However, their high synthesis cost has limited their widespread use. This study demonstrates a method of synthesizing CNTs from CO2 using electrolysis, which not only reduces synthesis cost but also consumes CO2 as a means of addressing climate change.

Summary: By utilizing carbon's reductive power, this study integrates dry reforming of methane and selective reduction of nitric oxide in a chemical looping process, achieving stable CO2 utilization and NO reduction with cyclic catalyst regeneration. The temporal-spatial separation of reactions in chemical looping allows for complete conversion of carbon and NO, ensuring a higher exergetic efficiency. Additionally, adapting the relative duration of the DRM and SRN steps to industrial point sources offers an attractive strategy for selective catalytic reduction of NO with greenhouse gases.

Summary: This paper proposes a greener and more sustainable process for producing syngas through chemical looping combustion combined with bi-reforming of methane with CO2. The process is advantageous in consuming greenhouse gases, overcoming catalyst deactivation, and producing syngas with the optimal H2/CO ratio for methanol synthesis. The integration of bi-reforming with CLC fulfills heat and CO2 requirements, making the process self-sustainable.

Summary: Desalination is an effective method for industrial water supply, but it generates a large amount of wastewater. This study proposes a novel process for recovering CO2 and SOx from desalination wastewater, which can capture and utilize about 91% of the CO2 and achieve a desulfurization efficiency of 99%. The process is profitable and suitable for large-capacity operations.

Summary: This paper explores the use of chemical looping dry reforming (CLDR) to intensify dry reforming of methane by improving its carbon balance and energy efficiency, producing separated syngas streams. Performance models compare different process configurations for supplying heat needed for the reforming reaction, showing that CLDR processes can significantly exceed conventional dry reforming in terms of syngas yield and CO2 utilization. The internal carbon combustion configurations showed the highest efficiency, demonstrating the potential for innovative process designs enabled by chemical looping schemes.

Summary: Power-to-methane (PtM) systems can smooth out fluctuations in renewable energy supply by storing surplus energy as methane. By combining hydrogen and carbon dioxide, these systems can produce methane through a chemical reaction. The study found that PtM systems based on CO2 from biomass have the potential to reduce global warming potential and effectively remove CO2 from the atmosphere through negative emissions.

Summary: Here, we present a synthetic approach to prepare and stabilize nanoclusters of various metals and metal salts. The method utilizes a Pickering stabilization effect within a microemulsion system, which allows for the encapsulation of nanoclusters in a silica matrix. The resulting nanocapsule exhibits a central cavity and a porous shell composed of both silica and nanoclusters, providing high thermal stability, good biocompatibility, and excellent photostability. This makes the nanoclusters suitable for both fundamental studies and practical applications in fields such as materials chemistry, catalysis, optics, and bioimaging.
