Als je CO2 met behulp van elektriciteit kan omzetten naar bouwstenen voor andere moleculen, kun je de chemische industrie flink verduurzamen. Leidse chemici hebben een fundamenteel onderdeel van dit proces ontrafeld en die kennis toegepast in een echt apparaat, schrijven ze in Nature Catalysis en Nature…

Stel dat wij kunnen wat groene planten kunnen: fotosynthese. Dan zouden we onze enorme energiebehoefte kunnen stillen met diepgroene waterstof en klimaatneutrale biodiesel. De afgelopen decennia werkten wetenschappers er volop aan. Chemicus Chengyu Liu promoveert 8 juni op weer een stap die kunstmatige…
