About this Research Topic
The need to transform carbon dioxide (CO2)-emitting industries towards climate-neutral and circular processes by 2050 is imperative due to the pressing worldwide need for sustainable development and the mitigation of climate change. To this end, the membrane intensification of the CO2 capture and purification technologies, as well as the valorization of the captured CO2 in chemicals and low-carbon liquid fuels, are expected to be crucial.
This Research Topic aims to highlight recent advancements in reducing the financial burden associated with the high cost of CO2 capture and CO2 conversion, based on breakthrough advances regarding the development of "next-generation" nano-enabled membranes and catalysts.
The issue will cover a range of topics, including:
• High CO2 permeance «next-generation» polymeric and mixed-matrix membranes.
• Hollow-fibre membrane contactors to remove CO2 and CO from flue gas and blast furnace gas.
• Ultra-thin Pd and molecular sieving membranes enable the removal of hydrogen to shift the equilibrium in steam-reforming membrane-intensified reactors.
• Modified zeolite and nanoporous membranes enable the removal of water to shift the equilibrium in novel membrane intensified CO2 hydrogenation reactors to methanol and DME.
• «Next-generation» nano-enabled catalysts for the efficient conversion of captured CO2 into valuable chemicals and fuels.
• «Next-generation» nano-enabled CO2 sorbents.
• Cost-effective hybrid membrane and sorption systems for CO2 capture from flue gas and biogas.
• Membrane-intensified dry reforming membrane reactors to produce green hydrogen from biogas.
• Growth of microalgae using CO2 for jet fuel production by hydrothermal liquefaction (HTL).
• Reduction of methanol fuel by the hydrogenation of CO2 with in-situ removal of the water produced.
• Preparation, and characteristics of porous solid activated carbon, or other porous materials and nano-materials via a cost effective method for carbon capture and sequestration.
