Title: Innovations of Sunho Choi in Carbon Dioxide Capture

Introduction

Sunho Choi is an accomplished inventor based in Chestnut Hill, MA (US). He has made significant contributions to the field of carbon dioxide capture, holding a total of 2 patents. His innovative approaches focus on developing effective methods for separating carbon dioxide from ambient air and flue gases.

Latest Patents

Choi's latest patents include "Regenerable immobilized aminosilane sorbents for carbon dioxide capture applications." This patent describes a method for separating carbon dioxide from ambient air and flue gases by coupling a phase-separating moiety with a second moiety onto an inert substrate. The resulting mixture is then contacted with flue gases or ambient air. The phase-separating moiety is an amine, while the second moiety is an aminosilane or a Group 4 propoxide, such as titanium (IV) propoxide. This innovative sorbent exhibits a high carbon dioxide loading capacity and considerable stability over hundreds of cycles, making it suitable for commercial and industrial production.

Another notable patent is "Application of amine-tethered solid sorbents to CO2 fixation from air." This method captures carbon dioxide from ambient air using solid tethered amine adsorbents. The amine adsorbents are covalently bonded to substrates like silica, metal oxides, and polymer resins. The process includes the adsorption of carbon dioxide, regeneration of the adsorbent at elevated temperatures, and recycling for further use.
