A diverse category of porous materials can separate and purify key industrial chemicals at low temperatures
Gas and liquid separation processes in the chemical industry could be made more efficient and environmentally friendly by using substances known as intrinsically porous materials (IPMs). KAUST researchers review the prospects for IPMs in the journal Accounts of Chemical Research. Niveen Khashab ...
Catalyst nanoparticles trap an unprecedented range of wavelengths of light to convert carbon dioxide into methane.
Atmospheric carbon dioxide (CO2) is a major driver of global warming, but this gas could also serve as a valuable resource. Researchers at KAUST have developed an efficient catalyst that uses light energy to convert CO2 and hydrogen into methane (CH4). This counteracts the release of CO2 when ...
Combining solar-harvesting materials with carbon-dioxide–consuming microbes could be an efficient way to generate clean fuels
Semiconductive photocatalysts that efficiently absorb solar energy could help reduce the energy required to drive a bioelectrochemical process that converts CO2 emissions into valuable chemicals, KAUST researchers have shown. Recycling CO2 could simultaneously reduce carbon emissions into the ...
Machine learning models can rapidly and accurately estimate key chemical parameters related to molecular reactivity
Creating computers that can teach themselves how chemical structure dictates the fundamental properties of molecules and then using that knowledge to predict the properties of novel molecules could help to design cleaner energy and industrial systems. KAUST researchers have developed a machine ...
Highly modular metal-organic framework-based materials show great potential for photocatalytic hydrogen production
A metal organic framework (MOF)-based water splitting photocatalyst, developed at KAUST, has brought researchers a step closer to generating clean hydrogen fuel using sunlight. "Using solar energy to efficiently make green fuels is the ultimate goal for many catalysis researchers," says Jorge ...
A water-stable dopant enhances and stabilizes the performance of electron-transporting organic electrochemical transistors
Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron transporting or n-type, organic electronic materials. Now, an approach developed by KAUST uses a dopant, an additive that boosts the electronic performance and water ...
An industrial process that currently consumes vast amounts of energy in petrochemical plants around the globe could be replaced by an alternative process so efficient that it requires no heating or elevated pressure. Niveen Khashab from KAUST's Advanced Membranes and Porous Materials Center and ...
By juggling four different chemical reactions in a single flask, researchers at KAUST have combined four polymers to form a single multicrystalline substance. Materials that seamlessly combine multiple polymers potentially merge the best aspects of each material. The versatile new approach for ...
Mixing microbes with carbon nanomaterials could help the transition to renewable energy. KAUST research shows microbes and nanomaterials can be used together to form a biohybrid material that performs well as an electrocatalyst. The material could be used in the solar-powered production of ...
From astronauts and submariners to miners and rescue workers, people who operate in small enclosed spaces need good air quality to work safely and effectively. Electronic sensors now developed by a KAUST team can simultaneously detect at least three critical parameters that are important to ...
