photosynthesis and «solar
fuels».»

photosynthesis, after multiple reactions, converts water, carbon dioxide and sunlight into oxygen and energy - rich
fuels such as sugar, Meyer's version converts water and carbon dioxide into oxygen, hydrogen and carbon monoxide — and the latter can be combined with hydrogen to eventually make a
fuel such as methanol.
Carbon dioxide - laden water from a fossil -
fuel plant would pass across ruthenium catalyst membranes, which would trigger artificial
photosynthesis, breaking it down into oxygen as well as constituents that can be converted to
fuel.
All over the world researchers are investigating solar cells which imitate plant
photosynthesis, using sunlight and water to create synthetic
fuels such as hydrogen.

They are ubiquitous in all niches of the biosphere, and their roles are clearly evident in reactions that
fuel the natural world, such as
photosynthesis and respiration.
I also learned that chemistry is a part of everything, including the development of alternative
fuels and how plants obtain food by
photosynthesis, which is really another
