Could water, sunlight, and air be all that’s needed to make hydrogen peroxide?

 

ITHACA, N.Y. - Cornell University scientists have discovered a potentially transformative approach to manufacturing one of the world’s most widely used chemicals – hydrogen peroxide – using nothing more than sunlight, water and air.

“Currently, hydrogen peroxide is made through the anthraquinone process, which relies on fossil fuels, produces chemical waste and requires transport of concentrated peroxide – all of which have safety and environmental concerns,” said Alireza Abbaspourrad, associate professor of Food Chemistry and Ingredient Technology, and corresponding author of the research.

Hydrogen peroxide is ubiquitous in both industrial and consumer settings: It bleaches paper, treats wastewater, disinfects wounds and household surfaces, and plays a key role in electronics manufacturing. Global production runs into the millions of tons each year. Yet today’s process depends almost entirely on a complex method involving hazardous intermediates and large-scale central chemical plants.

According to Amin Zadehnazari, first author and a postdoctoral researcher in Abbaspourrad’s lab, the new research introduces two engineered, light-responsive materials, dubbed ATP-COF-1 and ATP-COF-2, designed to absorb visible light, separate photogenerated charges and drive the conversion of water and oxygen into hydrogen peroxide.

“These materials work efficiently under visible light, are stable and reusable, and point toward a future where hydrogen peroxide could be made locally instead of in large chemical factories,” Zadehnazari said.

This means rather than shipping concentrated hydrogen peroxide from a few mega-factories, industries or even local treatment facilities could one day generate the molecule onsite using solar energy. That shift could reduce greenhouse-gas emissions, cut energy usage and improve safety–particularly in remote or resource-limited settings.

“The challenge,” Zadehnazari added, “is that while the existing anthraquinone process is toxic and not clean, it’s cheap. We’re now focusing on how to make this sustainable alternative affordable at scale.”

While the study is still at the laboratory scale, the researchers are now working to scale up the materials, optimize their performance and integrate the system into practical devices.

“It’s an exciting start,” Zadehnazari said. “This method could reshape how disinfectants and water-treatment agents are produced – making them cleaner, safer and more accessible.”

Making quieter dental drills to reduce dental anxiety

2025-12-02
HONOLULU, Dec. 2, 2025 — Dental anxiety, also known as odontophobia, prevents people from getting their regular cleanings and keeping up with necessary dental hygiene. One aspect of the anxiety comes from the sound of the dental drill, which makes a high-pitched whining sound. As a dentist, Tomomi Yamada has witnessed discomfort and fear in her patients firsthand. “Originally, I was doing research on dental materials, but I realized that almost no one — not even dentists — was tackling this sound problem scientifically,” Yamada said. Yamada, an assistant professor at the University of Osaka’s graduate ...

Why undisturbed sleep is important to brain injury recovery

2025-12-02
COLUMBUS, Ohio – A new study highlights how important uninterrupted sleep is to recovery after a traumatic brain injury, finding that fragmented sleep in injured mice is linked to a loss of rapid-eye-movement (REM) sleep and increased fatigue. Specifically, the research shows that fragmented sleep worsens symptoms that a traumatic brain injury (TBI) alone produces – and that mice without a head injury can make up for some REM sleep loss brought on by interruptions to sleep, but injured mice do not. REM sleep has a major role in helping the brain consolidate and process new information and is associated with better concentration and ...

Supplement trio shows promise in reversing autism-linked behaviors in mice

2025-12-02
Researchers led by Tzyy-Nan Huang and Ming-Hui Lin from Academia Sinica in Taiwan report that a low-dose mixture of zinc, serine, and branch-chain amino acids can alleviate behavioral deficits in three different mouse models of autism. Published December 2nd in the open-access journal in PLOS Biology, the study shows that when combined together, these three dietary supplements promote communication between neurons in the brain and improve social behaviors. Autism spectrum disorder (ASD) is known to result from abnormal neural development that affects how neurons are connected. ...

People who received emergency or hospital care for hallucinogens six times more likely to be diagnosed with mania

2025-12-02
People who have received emergency or hospital care in Canada due to hallucinogen use have a six-fold increased risk of receiving care for mania in the next three years, according to a study published December 2nd in the open-access journal PLOS Medicine by Daniel Myran from North York General Hospital in Canada and colleagues. Use of hallucinogens such as ketamine, lysergic acid diethylamide (LSD) or psilocybin has been increasing, both recreationally and in medical contexts for treatment of conditions such as depression or post-traumatic stress disorder. But there are safety concerns that these drugs might induce mania or trigger ...

Scientists call for greater focus on conserving whole ecosystems instead of charismatic species

2025-12-02
Conservation programs are often too focused on a single charismatic species, Hai-Tao Shi at Hainan Normal University in China and colleagues warn in a perspective article publishing December 2nd in the open-access journal PLOS Biology. With many species worldwide experiencing population declines, there is an urgent need for conservation initiatives to support their recovery. However, this urgency, combined with insufficient scientific knowledge about endangered species, means that conservationists have often relied on oversimplified measures of success. For example, historical conservation efforts often ...

Crickets munch on microplastics — especially if they have a big mouth

2025-12-02
To a human, microplastics are very small at less than 5 millimeters (mm) wide. But to an insect, microplastics might be the same size as the food they usually eat. Researchers reporting in ACS’ Environmental Science & Technology have shown that crickets can and will consume polyethylene microplastics if their mouth is larger than the plastic particle. The study suggests that crickets — and likely many other insects — cannot distinguish plastic from food. Previous research has shown that consuming microplastics negatively affects small animals like insects, snails and earthworms. These plastic particles, ranging in size from 1 micrometer (around the width ...

Iron-deficient diet prevents lung cells from fighting the flu

2025-12-02
NEW YORK, NY--Researchers at Columbia University have found that a lack of dietary iron early in life can prevent immune cells in the lung from making a key protein that helps fight viral infections, even after iron levels are restored.   The findings suggest that immunological memory formed when iron levels are low may not provide adequate protection against future exposures to the same viruses. “Iron deficiency, which disproportionally affects children, is one of the most common nutritional problems worldwide and has long been linked to ...
