Technologies to Capture CO2_2 directly from Ambient Air

Building a carbon-neutral world needs to remove the excess CO$_2$ that has already been dumped into the atmosphere. The sea, soil, vegetation, and rocks on Earth all naturally uptake CO$_2$ from the atmosphere. Human beings can accelerate these processes in specific ways. The review summarizes the present Direct Air Capture (DAC) technology that contribute to Negative Emissions. Research currently being done has suggested future perspectives and directions of various methods for Negative Emission. New generations of technologies have emerged as a result of recent advancements in surface chemistry, material synthesis, and engineering design. These technologies may influence the large-scale deployment of existing CO$_2$ capture technologies in the future

Water-stable MOFs and Hydrophobically Encapsulated MOFs for CO2 Capture from Ambient Air and Wet Flue Gas

The extra CO2 that has already been released into the atmosphere has to be removed in order to create a world that is carbon neutral. Technologies have been created to remove carbon dioxide from wet flue gas or even directly from ambient air, however these technologies are not widely deployed yet. New generations of creative CO2 capture sorbents have been produced as a consequence of recent improvements in material assembly and surface chemistry. We summarize recent progress on water-stable and encapsulated metal-organic frameworks (MOFs) for CO2 capture under a wide range of environmental and operating conditions. In particular, newly developed water-stable MOFs and hydrophobic coating technologies are discussed with insights into their materials discovery and the synergistic effects between different components of these hybrid sorbent systems. The future perspectives and directions of water-stable and encapsulated MOFs are also given for Direct Air Capture of CO2 and CO2 capture from wet flue gas

Perspectives from the 2022 cohort of the American Chemical Society Summer School on Green Chemistry & Sustainable Energy

The field of chemistry is uniquely equipped to solve many current and impending global challenges; however, minimizing potential negative impacts on the environment, society, and the economy requires a holistic approach to developing new processes and chemicals. For this reason, there is an urgent need to incorporate green chemistry and systems thinking into chemistry-based disciplines so that the most sustainable, least toxic, and least resource-intensive research directions and methods are prioritized. The next generation of researchers and instructors is poised to implement these approaches; however, most graduate curricula do not include coursework on green chemistry and systems thinking. Every year, the American Chemical Society Green Chemistry Institute hosts the Summer School on Green Chemistry & Sustainable Energy for early career researchers to learn about green chemistry and systems thinking approaches for tackling sustainability goals. In this Perspective, 2022 summer school participants highlight sustainability challenges in their own work that can be addressed using the skills and knowledge acquired at the summer school, including in carbon capture, organic pharmaceutical synthesis, nanomaterial synthesis, catalysis, and other areas. In addition, how green chemistry can meet practical needs in industry settings and be infused in education and government policy is discussed.Fil: Saraf, Mohit.
