Water Splitting

A group of researchers has made significant progress in developing cost-effective catalysts for the oxygen evolution reaction (OER), a critical component in technologies such as water splitting and metal-air batteries.

Recent research published in National Science Review by a team led by Dr. Rong Cao and Dr. Minna Cao from the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, and Dr. Dongshuang Wu from Nanyang Technological University, Singapore, has demonstrated the successful design and synthesis of a series of sub-10 nm core-shell nanocatalysts consisting of an Au core and an AuxIr1-x alloy…

Scientists have found a way to harvest hydrogen from plastic waste.

Chemists from the National University of Singapore (NUS) have developed a scalable hydrothermal approach for obtaining ferromagnetic single-atom spin catalysts which can boost the efficiency of water splitting reactions under the influence of a magnetic field.

Hydrogen produced from renewable energy sources can be used as fuels that do not contribute to CO2 emissions, and therefore is emerging as an important future power source.

CNBC's Sustainable Future takes a look at the emerging pink hydrogen sector and the role it could play in the planet's shift to a low-carbon future.

To date, nanoparticles as catalysts for green hydrogen have been like rowers in an eight: researchers could only measure their average performance, but couldn't determine which one was the best. This has now changed following the development of a new method by the group led by Professor Kristina Tschulik, head of the Chair of Electrochemistry and Nanoscale Materials at Ruhr University Bochum, Germany.

Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as alternative energy. However, their effectiveness is restricted at low voltage. A research team led by scholars from City University of Hong Kong (CityU), Australia and Germany successfully mediated the poor charge carrier transport at low voltage by adding phosphorus to a metal oxide catalyst, which reduced…

Our excessive consumption of fossil fuels is responsible for some of the major societal challenges we are facing, from climate change to pollution. Hydrogen is considered a green alternative to fossil fuels, and alkaline water electrolysis is proving an attractive technology for large-scale commercialization of hydrogen production.

Hydrogen has drawn attention in recent years as a potential source of clean energy because it burns without producing climate-damaging emissions. However, traditional hydrogen production methods have a substantial carbon footprint, and cleaner methods are expensive and technically complex.

Some of the economic sectors that are the hardest to decarbonize would benefit from the emergence of substantially more efficient catalysts involved in energy conversion chemical reactions. A breakthrough here might depend upon the use of pigments widely deployed in biological processes integrated as a catalyst into novel and highly porous molecular structures that act sort of like sponges.

The coal plant is closing. In this tiny Utah town surrounded by cattle, alfalfa fields and scrub-lined desert highways, hundreds of workers over the next...

Hydrogen energy is one tool that could slow climate change, but we aren't there yet.

Hydrogen has attracted extensive attention from academia and industry as an energy source due to its intrinsic environmental compatibility, abundance, and high energy density (120 MJ kg−1). Electrocatalytic water splitting is an environmentally friendly route to produce hydrogen, especially when the electricity is from renewable sources that minimize carbon dioxide emissions throughout the process.

UCSC chemists developed a simple method to make aluminum nanoparticles that split water and generate hydrogen gas rapidly under ambient conditions.

China's bet on hydrogen fuel cell vehicles may be the wrong one.

Researchers at Shinshu University in Japan have built a novel reactor to manufacture renewable hydrogen fuel directly from sunlight and water. It's still an early prototype, but...

Scientists in Japan have demonstrated a new method to create hydrogen fuel without emitting greenhouse gases. But key steps to improve its efficiency remain for it to be commercially viable.
