Figure showing the systematic design of the photocatalytic covalent organic frameworks (COFs) for manufacturing hydrogen peroxide using flow reactors. (a) The COF with segregated donor and acceptor ...

By fine-tuning the surroundings of single cobalt atoms, researchers reveal how tiny design changes can steer oxygen reactions toward cleaner and more efficient hydrogen peroxide production.

National University of Singapore (NUS) chemists have developed hexavalent photocatalytic covalent organic frameworks (COFs) which mimic natural photosynthesis for the production of hydrogen peroxide ...

When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of ...

A photoelectrochemical device uses sunlight, water, and oxygen to produce hydrogen peroxide efficiently, stably, and at scalable rates without grid electricity. (Nanowerk Spotlight) Hydrogen peroxide ...

A metal-air battery has a metal like zinc as the anode (negative electrode) and ambient air as the cathode (positive electrode). When the battery discharges – releases energy – oxygen from ambient air ...

Chemists have synthesised new metal-free photocatalysts that can be used to produce hydrogen peroxide from pure air and natural water 1. Using the Sun’s energy, the catalysts convert air and water ...

However, such an artificial system faces three key challenges: (1) insufficient charge carrier generation and fast charge recombination, which lowers the efficiency; (2) limited number of available ...
