The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions ...

Tiny changes at the atomic scale can determine the future of clean energy. In a new study, Tohoku University researchers have revealed how the precise coordination environment surrounding a single ...

Electrocatalytic reduction reactions, powered by clean energy, offer a sustainable approach to upgrading inexpensive feedstocks into high-value-added chemicals. Recently, cations in the electrolyte ...

Long-haul truckers and diesel engine enthusiasts had to rethink their entire operations in 2010 when the Environmental Protection Agency mandated selective catalytic reduction technology. Selective ...

Pollutants emitted from combustion sources have been regulated by local and federal governments since the early 1960s. Specific rules vary by state and air district, but they generally apply to ...
