New porous coordination polymer captures CO2, converts it to useful organic materials

Green Car Congress

A new material that can selectively capture CO 2 molecules and efficiently convert them into useful organic materials has been developed by researchers at Kyoto University, along with colleagues at the University of Tokyo and Jiangsu Normal University in China. —Wu et al.

Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Green Car Congress

Researchers at Stanford University have shown that porous polymer encapsulation of metal-supported catalysts can drive the selectivity of CO 2 conversion to hydrocarbons. The research team encapsulated a supported Ru/TiO 2 catalyst within the polymer layers of an imine-based porous organic polymer that controls its selectivity.

Researchers develop thin-layer artificial biofilm technology for green ethylene production

Green Car Congress

PCC 6803 cells holding ethylene forming enzyme (Efe) from Pseudomonas syringae are entrapped within a natural polymer matrix, thus forming the thin-layer biocatalytic structure. 2 ethylene at 1.54% light to ethylene conversion efficiency. It is the main building block in the production of plastics, fibers and other organic materials.

U-M researchers nearly double efficiency of organic thermoelectric materials

Green Car Congress

A research team from the University of Michigan has nearly doubled the efficiency of certain organic thermoelectric materials. These convert heat into electricity more than four times as efficiently as the organic semiconductors created to date. for organic semiconductors. in a compound known as PEDOT:PSS. Resources.

LLNL 3-D printed biocatalytic polymer turns methane to methanol at room temperature and pressure

Green Car Congress

Methane monooxygenases (MMOs), found in methanotrophic bacteria, are selective catalysts for methane activation and conversion to methanol under mild conditions; however, these enzymes are not amenable to standard enzyme immobilization approaches. The enzymes retain up to 100% activity in the polymer construct. Blanchette et al.

NREL modifies organism to produce ethylene via photosynthesis: alternative to fossil-fuel based ethylene for chemicals and transportation fuels

Green Car Congress

PCC 6803—and demonstrated that the organism remained stable through at least four generations, producing ethylene gas that could be easily captured. The organism produced ethylene at a high rate and is still being improved. And it isn’t going to be a food buffet for other organisms. into a cyanobacterium— Synechocystis sp.

New one-pot conversion of CO2 to polycarbonate copolymers

Green Car Congress

Researchers at Texas A&M have developed a two-step, one-pot conversion of CO 2 and epoxides (highly reactive compounds with a three-membered ring made of two carbon atoms and one oxygen atom) to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.
