Artificial Photosynthesis: Chemical Synthesis Powered by Sunlight 2015-068
ABSTRACT: For the researchers' complete publication ACS NanoLetters, go here. Direct solar-powered production of value-added chemicals from CO2 and H2O, a process that mimics natural photosynthesis, is of fundamental and practical interest. In natural photosynthesis, CO2 is first reduced to common biochemical building blocks using solar energy, which are subsequently used … [Read more...] about Artificial Photosynthesis: Chemical Synthesis Powered by Sunlight 2015-068
