Imagine trying to clean up the air by using sunlight to convert CO2 into something useful. This is what scientists call photocatalytic CO2 reduction. Titanium dioxide (TiO2) is a popular material for this job, but it's not perfect. Impurities like sulfur dioxide (SO2) can mess things up. Scientists
Scientists have found a way to turn highly soluble radioactive waste into a less soluble form using a process called photocatalysis. This method is great for cleaning up contaminated water, but it has a big problem: nitrates can get in the way. These nitrates compete with the radioactive elements fo
A recent study explored a new approach to improve photocatalytic performance by using alternating donor-acceptor (D-A) units in graphitic carbon nitride (g-C3N4). The researchers created a series of metal-free photocatalysts, named CNBTC-X, by combining g-C3N4 with different amounts of 5-bromo-2-thi
Imagine you're trying to build a better machine for breaking down pollutants in water. One clever way to do this is by tweaking the machine's tiny parts, creating some missing pieces on purpose. In this case, scientists used ZnIn 2 S 4 nanosheets and left out some zinc atoms, creating what are
