Scientists from Nanyang Technological University, Singapore, have designed a device that harvests sunlight to generate clean hydrogen from seawater and simultaneously degrades hydrazine, a highly toxic contaminant from industrial wastewater.

Inspired by leaves, the device directly captures sunlight and converts it into electricity to drive the reaction without the need for external power sources. The innovation is published in Nature Communications.

Two-in-one green solution
To produce green hydrogen from water, an electric current is passed through water between two electrodes, splitting the water molecules into hydrogen and oxygen—a process known as electrolysis.

In electrolysis, ...

Researchers have developed a solar-powered reactor to break down hard-to-recycle forms of plastic waste—such as drink bottles, nylon textiles and polyurethane foams—using acid recovered from old car batteries, and converting it into clean hydrogen fuel and valuable industrial chemicals. The results are reported in the journal Joule.

The reactor, developed by researchers from the University of Cambridge, is powered by the energy from the sun, and could be a cheaper, more su...
