State of the art and perspectives of the CO2 chemisorption in ceramics with its simultaneous or subsequent chemical transformation

Recycling Spent LiFePO4 Battery to Prepare Low-Cost Li4SiO4 Sorbents for High-Temperature CO2 Capture

“…In comparison, the specific surface area and pore volume of Li 4 SiO 4 -SA and Li 4 SiO 4 -AA have limited increase during the repeated cycles. It seems that these two sorbents have fewer surface adsorption sites after 20 cycles, which is not conducive to maintaining a good cyclic stability. , Figure e shows the in situ XRD diagram of three sorbents by rising the temperature to 900 °C under CO 2 atmosphere. It is found that all sorbents generally show a trend of CO 2 adsorption followed by desorption.…”

Enhanced hydrogen production via assisted biomass gasification using lithium manganate as a bifunctional material

“…35,36 Moreover, it has been reported that the addition of different metal oxides or supported metal-particles as catalysts in addition to CO 2 sorbents during the pyrolysis and gasification processes enhance the production and increases the purity of H 2 . 19,37–41…”

“…35,36 Moreover, it has been reported that the addition of different metal oxides or supported metal-particles as catalysts in addition to CO 2 sorbents during the pyrolysis and gasication processes enhance the production and increases the purity of H 2 . 19,[37][38][39][40][41] In this context, alkaline ceramics have demonstrated high capture capabilities for CO 2 and/or bifunctional properties for consecutive processes, such as CO oxidation and subsequent chemisorption. In fact, Li 4 SiO 4 and Na 2 ZrO 3 have been reported as bifunctional catalyst-sorbent materials during the pyrolysis process, enhancing the H 2 production and chemically trapping CO 2 as carbonates.…”

Kinetic Modeling of Glucose Oxidation to Tartaric Acid over Monometallic Pt/TiO2 and Bimetallic AuPt/TiO2 Catalysts: Role of Bimetals on C–H and C–C Cleavages

“…Tartaric acid (TA), an important diprotic C 4 -based organic acid, is widely used in pharmaceutical and cosmetic industries. − TA is also often applied as a sour agent in the food industry and a resolving agent in the synthesis of bioactive molecules. , In nature, TA exists in a variety of fruits (e.g., grapes). − It can be obtained through various biological and chemical processes (Figure ). , Traditionally, it was obtained as a crude solid byproduct from wine fermentation. , The productivity and quality were strongly influenced by the growth of grapes and climatic conditions . A chemical synthesis method using maleic anhydride has been found to significant discharge wastewater containing heavy metals. − Enzyme catalysis is another effect way to produce TA, owing to high substrate conversion and product purity. , Specifically, maleic acid is epoxidized to cis -epoxy succinic acid, after which utilizes relevant hydrolase produced by microorganisms to obtain TA. , However, biotransformation technologies still suffer from low productivity. , An alternative method involving direct synthesis of TA from glucose oxidation using bimetallic AuPt/TiO 2 catalysts has been reported recently. , This synthetic method provides a promising route for the production of various downstream polymers and pharmaceutical products. − …”
