Research develop new non-toxic method for producing high-quality graphene oxide

Researchers at Sweden's Umeå University, Lund University and Denmark's Aarhus University have reported a new way to synthesize graphene oxide, which has significantly fewer defects compared to materials produced by the most common method. To date, graphene oxide of similarly good quality could only be synthesized by using a rather dangerous method involving extremely toxic fuming nitric acid.

Graphene oxide is often used to produce graphene by removing oxygen. However, if there are holes in graphene oxide, there will also be holes after it is converted to graphene. Therefore, the quality of the graphene oxide is very important. Umeå University's Alexandr Talyzin and his research group have now addressed the issue of how to safely make good graphene oxide.

Rimere secures $10 Million for tech that enables the production of clean hydrogen and graphene

According to a recent press release, Rimere, a company specializing in climate solutions, has closed a $10 million strategic investment from Clean Energy Fuels Corp., aimed at advancing the development and field testing of its proprietary plasma technology. This technology is designed to reduce emissions from natural gas infrastructure and facilitate the production of clean hydrogen and graphene.

The investment will accelerate the deployment of Rimere’s two devices, the Reformer and the Mitigator. The Reformer employs a sequential hybrid plasma process to convert natural gas into hydrogen and high-quality graphene, a process that remarkably does not produce CO2 emissions. In particular, when renewable natural gas is utilized, the hydrogen generated can achieve a negative carbon intensity rating.

GMG comissions modular graphene production plant

Graphene Manufacturing Group (GMG) has announced the commissioning of its natural gas to graphene production plant in manufacturing facility at Richlands, Australia.

The facility is based on the GMG plasma technology with which the Company's existing production plant has been making graphene for over five years, however this new plant is built in a modular fashion which can allow more production units to be installed as the sales of Company's products grows. GMG expects to be able to install at least an additional 20 graphene production units in the Richlands manufacturing facility with most of the supporting infrastructure for these additional production units already installed as part of this initial project.

HydroGraph announces partnership with Manchester U's GEIC and expands application development

HydroGraph Clean Power, a manufacturer of graphene, has announced it is expanding its application development capabilities to meet growing global demand by establishing a partnership with the University of Manchester’s Graphene Engineering Innovation Center (GEIC) commencing in October of 2023. 

This strategic collaboration will aim to significantly enhance and ‘de-risk’ HydroGraph's application development capabilities. The GEIC, formed to commercialize graphene-related technologies and products, specializes in rapidly scaling up applications involving composites, building materials, membranes, inks, and coatings. To support their mission the £60 million GEIC facility was established with significant lab and engineering space that houses state-of-the-art testing and application development equipment, supported by experienced and knowledgeable team. Hydrograph will scale up this critical application development work by leveraging the resources at the GEIC with a team of commercially focused scientists and engineers to support industry adoption of its "99.8% pristine fractal graphene".

Rice team produce hydrogen and graphene from waste plastic at zero net cost

Rice University researchers have found a way to harvest hydrogen and graphene from plastic waste using a low-emissions method that could more than pay for itself.

“In this work, we converted waste plastics ⎯ including mixed waste plastics that don’t have to be sorted by type or washed ⎯ into high-yield hydrogen gas and high-value graphene,” said Kevin Wyss, a Rice doctoral alumnus and lead author of the recent study. “If the produced graphene is sold at only 5% of current market value ⎯ a 95% off sale! ⎯ clean hydrogen could be produced for free.”
