Getting it to stick: Grabbing CO₂ out of the air

Direct air capture is hard to do - Pitt researchers are designing new materials that selectively catch carbon dioxide in the atmosphere

13-Oct-2022 - Direct air capture may be key to saving Earth from the effects of climate change, but there’s a catch: It’s really hard to do. Direct air capture (DAC) technologies are designed to remove carbon dioxide from the air, although there’s still a lot of room for improvement in DAC materials. Other ...

International research project achieves record in converting carbon dioxide into fuels

Artificial leaf

11-Oct-2022 - In an international research project involving the Technische Universität Ilmenau, scientists have succeeded in developing a sunlight-powered device that converts carbon dioxide directly into usable fuels with an efficiency of over five percent. This brings closer the goal of not only eliminating ...

On-site reactors could affordably turn CO₂ into valuable chemicals

“I’m excited by the potential of this technology”

10-Oct-2022 - New technology developed at the University of Waterloo could make a significant difference in the fight against climate change by affordably converting harmful carbon dioxide (CO2) into fuels and other valuable chemicals on an industrial scale. Outlined in astudypublished in the journal Nature ...

Wrapping of nanosize copper cubes can help convert carbon dioxide into other chemicals

26-Sep-2022 - Researchers found a new way to reduce carbon dioxide (CO2) emissions by wrapping copper nanocubes with an organic layer, solving instability and selectivity problems with copper nanocubes in catalysis, and improving how this electrocatalyst converts CO2 into organic molecules. As the need to ...

Fuel from a Greenhouse Gas

Single gold atoms catalyze the selective methanization of carbon dioxide

15-Sep-2022 - One step toward carbon dioxide (CO2) neutrality and the mitigation of both the greenhouse effect and the energy crisis would be to convert CO2 into hydrocarbon-based fuels like methane using light. In the journal Angewandte Chemie, a Chinese research team has introduced a highly effective ...

New method converts carbon dioxide into chemical

13-Sep-2022 - A team of researchers led byMeeneshSingh at University of Illinois Chicago has discovered a way to convert 100% of carbon dioxide captured fromindustrial exhaustinto ethylene, a key building block for plastic products. Their findings are published inCell Reports Physical Science. While ...

Recycling Greenhouse Gases

Novel perovskite catalysts could be used wherever methane and carbon dioxide are produced simultaneously

05-Sep-2022 - CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted ...

Lessons from natural photosynthesis: conversion of CO₂ to raw materials for plastic!

Technology sequesters CO₂ emissions

31-Aug-2022 - In plants, natural photosynthesis binds carbon dioxide (CO2­) to organic compounds, which can then be converted into glucose or starch. These useful molecules can be sequestered, storing the carbon in a solid form. Artificial photosynthesis mimics this process by reducing the greenhouse gas CO2– ...

Direct conversion of carbon dioxide into bulk chemicals and liquid fuels

30-Aug-2022 - High-efficiency utilization of CO2 facilitates the reduction of CO2 concentration in the global atmosphere and hence the alleviation of the greenhouse effect. The chemical utilization of CO2, which refers to converting CO2 into value-added chemicals and liquid fuels, has a distinct and direct CO2 ...

Efficient carbon dioxide reduction under visible light with a novel, inexpensive catalyst

“We believe that our study provides an unprecedented opportunity for developing a new class of inexpensive photocatalysts for CO₂ reduction consisting of earth-abundant elements”

25-Aug-2022 - The carbon dioxide (CO2) released into the atmosphere during fossil fuel burning is a leading cause of global warming. One way to address this growing threat is to develop CO2 reduction technologies, which convert CO2 into useful chemicals, such as CO and formic acid (HCOOH). In particular, ...
