Efficient carbon dioxide reduction under visible light with a novel, inexpensive catalyst

“We believe that our study provides an unprecedented opportunity for developing a new class of inexpensive photocatalysts for CO₂ reduction consisting of earth-abundant elements”


The carbon dioxide (CO2) released into the atmosphere during fossil fuel burning is a leading cause of global warming. One way to address this growing threat is to develop CO2 reduction technologies, which convert CO2 into useful chemicals, such as CO and formic acid (HCOOH). In particular, ...
