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.

Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. A paper on their work is published in the journal Nature Materials.

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

Green Car Congress

The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. However, weak gas-binding ability and/or poor sample crystallinity after guest exchange hindered the development of efficient materials for CO 2 incorporation, activation and conversion.

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.
