Carbon dioxide (CO2) emissions from human activities have risen drastically over the last century and a half and are seen as the primary cause of global warming and abnormal weather patterns. So, there has been considerable research focus, in a number of fields, on lowering our CO2 emissions and its atmospheric levels. One promising strategy is to chemically break down, or ‘reduce,’ CO2 using photocatalysts—compounds that absorb light energy and provide it to reactions, speeding them up. With this strategy, the solar powered reduction of CO2, where no other artificial source of energy is used, becomes possible, opening doors to a sustainable path to a sustainable future.
