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

Researchers at the University of Turku in Finland have developed a thin-layer artificial biofilm technology for sustainable and long-term ethylene photoproduction. 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.

U Delaware team develops chemocatalytic process to convert waste polypropylene to lube oils

Green Car Congress

Researchers at the University of Delaware have shown that ruthenium deposited on titania is an active and selective catalyst for breaking down polypropylene into valuable lubricant-range hydrocarbons with narrow molecular weight distribution and low methane formation at low temperatures of 250 °C with a modest H 2 pressure. 1c00874.
