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. Here, we present a dynamic porous coordination polymer (PCP) material with local flexibility, in which the propeller-like ligands rotate to permit CO 2 trapping.

New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. A paper on their work is published in the journal Science.

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.

Twelve and LanzaTech successfully convert CO2 to ethanol

Green Car Congress

Our partnership with Twelve provides us with the feedstock needed to create critical resources like ethanol without adding CO 2 to the atmosphere. Polypropylene is a major polymer used in key applications, including medical devices like syringes and IV bags, automotive, furniture, textiles, and other durable products.

Lifecycle CO2 balance of Mercedes-Benz EQC as low as 17.1t CO2 with hydropower

Green Car Congress

In order to gauge a vehicle’s environmental compatibility, the experts consider all emissions and the use and consumption of resources over the entire lifecycle. In production, the drive components specific to the EQC also require a greater use of material and energy resources compared to a conventionally powered vehicle.
