UAE researchers develop innovative green catalyst from desert sand and date pits

Researchers over at United Arab Emirates University have come up with a pretty interesting green catalyst. It’s made from desert sand, charcoal produced from date pits, and nickel , a combination that hints at new ways to turn local waste into materials suited for clean-energy tech.

According to the university, this work actually taps into two resources the UAE has plenty of but often doesn’t give enough attention to: the sand native to the desert environment and agricultural leftovers from dates. It’s also part of a broader research trend within the country, where scientists keep exploring how the region’s most familiar crop , the date palm , can be put to use beyond just food.

Dr Mohammed Noor Al Tarawneh, who’s an associate professor in the department of chemical and petroleum engineering and a key researcher behind this project, explained that the initiative signifies a shift towards leveraging local resources for creating advanced materials aimed at future clean energy solutions. He added that this method provides a kind of blueprint for transforming what’s already around us into practical, industrial-grade materials.

Before settling on the final recipe, the team tested 30 different mixes, trying to find the best mix of ingredients. The one they settled on contains 15% nickel, 42.5% desert sand, and 42.5% biochar, made from date pits. The researchers say this particular composition offered the strongest overall performance.

Their work was published in the Journal of Alloys and Compounds, involving teams from the university’s departments of chemical and petroleum engineering, chemistry, and also Abu Dhabi Polytechnic. This project aligns with a growing trend in UAE research, especially around waste-to-value technologies that are suited to the local agricultural and desert conditions.

It’s worth noting , and I find this pretty interesting , that this builds upon earlier studies by the same university, which looked at how date palm by-products could serve as energy sources. For example, reports say researchers found ways to extract oil from Khalas date pits for biodiesel, achieving about 90% efficiency. Plus, Gulf News covered another project where UAE University teams produced biofuels from oil extracted from date seeds, noting the country’s date palms dump roughly a million tonnes of seeds each year.

Collectively, these efforts suggest that the date palm could end up playing a bigger role in the UAE’s energy shift than many might imagine. What was once considered just agricultural waste is now being seriously explored as a raw material for fuels, carbon materials, and catalytic systems.

This whole area is really important for a country like the UAE, where goals around sustainability and innovation are super interconnected. Developing clean-energy solutions often involves importing costly specialised materials, especially for advanced catalysts and other high-end components. So, research that makes use of local sand and agricultural leftovers could cut down on dependency on external supplies, and help grow local economies in a circular way.

And speaking of the sand , well, desert sand is everywhere, but it’s not typically viewed as a top-tier industrial ingredient. In this research, though, it’s being used not just as a filler but as part of a carefully engineered material system. The addition of nickel grants the catalyst its functionality, while biochar from date pits offers a carbon-rich scaffold that enhances overall performance.

This combo fits in pretty well with wider trends in green chemistry. Scientists are on the lookout for ways to make catalysts more sustainable , more affordable, and easier to scale up , and not just effective in a lab. The real challenge is making sure these materials stay stable when used in real-world conditions. Dr Al Tarawneh said the research team now plans to investigate how well this catalyst retains its activity over extended periods, whether it can be reused, and how it performs under different operational settings.

Those are crucial next steps because, honestly, a lot of promising lab-made materials tend to struggle when exposed to the realities of industrial use , heat, pressure, or varying feedstocks can be big hurdles. Reusability, in particular, is a key factor deciding whether a new material can actually make the jump from the lab to industry, where long-term durability often makes or breaks its commercial viability.

If future testing goes well and the catalyst proves durable, it could bolster further UAE-based efforts to turn local waste into valuable industrial inputs. Naturally, this aligns with the country’s wider goals around clean energy, resource efficiency, and fostering innovative solutions domestically.

For investors and researchers working on climate tech in the UAE, the study raises an important point: the environment right here really can be part of the solution. Desert sand, date pits, and the region’s engineering know-how may not seem like obvious partners , I mean, at first glance , but in the hands of dedicated researchers, they’re transforming into something that could be relevant for future energy systems.

The real takeaway? It’s not just about the chemistry. It’s about the broader idea that building a sustainable economy doesn’t necessarily mean relying solely on imports or high-tech fancy materials. Sometimes, the answer is hidden right under our noses, in the resources we already have around us.
