Greening hydrocarbon separation and crude oil refining

Polymer-based membranes that selectively separate hydrocarbon and crude oil mixtures could eclipse current industrial thermal processes

01-Sep-2022

Polymer-based membranes developed at KAUST could enable greener and cheaper industrial separation approaches. Their stability and selectivity can be tuned by thermal crosslinking to separate simple hydrocarbon mixtures and complex crude oil fractions. Separation processes, such as distillation ...

Tip tricks control reactions in a single molecule

Pulses from an atom-sharp tip enable researchers to break and form chemical bonds at will

31-Aug-2022

Chemical reactions often produce messy mixtures of different products. Hence, chemists spend a lot of time coaxing their reactions to be more selective to make particular target molecules. Now, an international team of researchers has achieved that kind of selectivity by delivering voltage pulses ...

Organic water splitters get a boost

Nanoparticle photocatalyst can generate hydrogen fuel from water more efficiently than their standard inorganic semiconductor counterparts

14-Jun-2022

Organic semiconductor-based photocatalysts conceived by a KAUST-led team could make hydrogen easier to generate from water using sunlight. Sunlight is the most abundant source of renewable energy, but its inability to produce consistent energy levels over time means it cannot meet energy needs on ...

Smog clears on car exhaust catalyst design

Systematic study resolves a debate on the best combination of metals to catalytically clean NOx from vehicle emissions

09-Jun-2022

Smog-producing chemicals could be almost eliminated from the tailpipes of diesel cars and vans, using a new exhaust catalyst concept developed at KAUST. After systematically studying multiple catalyst compositions, the research team identified the ideal atomic recipe to catalytically remove NOx ...

Easing oxygen's evolution

An electrode made from inexpensive earth-abundant metals bubbles with potential for green fuel production

14-Mar-2022

A metal foam could underpin a low-cost method for generating carbon-free fuels, researchers from KAUST have shown. The team seamlessly coated the foam with iron and cobalt nanomaterials to create a highly active electrode for a device that splits water molecules to release oxygen and hydrogen, a ...

Shrimply the best composite membranes

Waste materials are used to create an environmentally friendly filtration system for industrial applications.

31-Jan-2022

Shrimp shells, plant extracts and recycled plastic have helped KAUST researchers to build a sustainable thin-film composite membrane that could replace conventional membranes whose environmental toll is greater. Thin-film composite membranes are widely used in applications such as wastewater ...

Making light work of emerging micropollutants

Dangerous and environmentally harmful organic micropollutants can be successfully removed from wastewater using high-intensity pulses of light

12-Jan-2022

Carbon-based organic micropollutants in water can be removed by treatment with high-intensity pulses of light in a procedure developed and demonstrated by researchers at KAUST. This photodegradation process was already known to be feasible, but its use was limited by the long treatment times it ...

Methane from Carbon Dioxide

Efficient catalyst for the light-driven methanation of CO2

19-Nov-2021

Recycling carbon dioxide (CO2), especially through conversion to methane (CH4), is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water upon ...

Recycling CO2 to fuel a carbon-neutral future

The conversion of captured CO2 into fuels and other valuable hydrocarbons could enable a sustainable nonfossil-fuel-based economy

16-Nov-2021

Multifunctional catalysts that transform captured carbon dioxide (CO2) into fuels and other valuable petrochemicals have been developed at KAUST and are set to enable a sustainable greener economy independent of conventional fossil fuels. The catalysts could help reverse the ever-increasing ...

Fine-tuned hydrocarbon separation at low energy cost

Metal organic framework membranes that selectively separate hydrocarbons set the stage for more sustainable petrochemical processes

24-Sep-2021

An electrochemical approach developed at KAUST produces molecular-sieving membranes that could enable a cheap energy-efficient separation of light hydrocarbons, such as olefins and paraffins. This separation, critical for the petrochemical industry, usually relies on extremely energy-intensive ...
