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.

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.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. There are several ways to do such conversions, including electrochemical, thermocatalytic, photothermal, or photochemical processes—each with their own problems or challenges.
