Solar-driven chemistry: towards new catalytic solutions for a sustainable world

Metrics details. The biological reduction of CO 2 driven by sunlight via photosynthesis is a crucial process for life on earth. However, the conversion efficiency of solar energy to biomass by natural photosynthesis is low. This translates in bioproduction processes relying on natural photosynthesis that are inefficient energetically. Recently, hybrid photosynthetic technologies with the potential of significantly increasing the efficiency of solar energy conversion to products have been developed. In these systems, the reduction of CO 2 into biofuels or other chemicals of interest by biocatalysts is driven by solar energy captured with inorganic devices such as photovoltaic cells or photoelectrodes.

Hydrogen generated from solar-driven water-splitting has the potential to be a clean, sustainable and abundant energy source.

The topic of production of useful chemical compounds with the help of solar light has been debated at a recent meeting organized in Rome on October 18 and 19, , by the Accademia Nazionale dei Lincei. Some of the contributions presented at this event are collected in this special issue of the Rendiconti Lincei. Scienze fisiche e Naturali. In this paper, we briefly discuss some recent results concerning the use of solar energy by artificial photochemical reactions for four important applications: i conversion of solar energy into fuels or ii conversion of sunlight into electrical energy, iii use of solar energy to perform organic synthesis that cannot be obtained by conventional chemistry, and iv photochemical reactions to reduce pollution. Mankind is exploiting without respite the limited resources of our planet.

Current challenges in photosynthesis: From natural to artificial

B Corresponding author. Email: ann. Her research includes manganese- and ruthenium-manganese complexes aimed at artificial photosynthesis, as well as the photosynthetic enzymes of nitrogen fixing cyanobacteria. His research concerns the water oxidizing enzyme Photosystem II, as well as development of solar fuels using synthetic manganese-, cobalt- and ruthenium-manganese complexes for artificial photosynthetic oxidation of water.

Wrighton directs a laboratory at the Massachusetts Institute of Technology's Chemistry Department, where active research into the development of workable laboratory synthesis of the process is under way. As chemists have known for many decades, the chemical energy he referred to comes from the breakdown of carbon dioxide CO 2 and water H 2 O , driven by photons of light, and leads to production of carbohydrates that nourish plants and of oxygen O 2 , which is vital to aerobic organisms.

Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis to convert sunlight , water , and carbon dioxide into carbohydrates and oxygen. The term artificial photosynthesis is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel a solar fuel. Photocatalytic water splitting converts water into hydrogen and oxygen and is a major research topic of artificial photosynthesis. Light-driven carbon dioxide reduction is another process studied that replicates natural carbon fixation.

The new gold rush in the digital world is all about renewable energy. But more than that, it is about making this energy reliable, which means finding ways to not just generate it but to store it when it is not needed and release it when it is needed.

 Клянусь, - сказал. Она смотрела на него с недоумением. - Надеюсь, это не уловка с целью заставить меня скинуть платье.

Сьюзан попробовала что-то сказать, но Джабба ее перебил: - Чего вы ждете, директор. Позвоните Танкадо.

Сьюзан была озадачена. - Это по-латыни, - объяснил Хейл.  - Из сатир Ювенала. Это значит - Кто будет охранять охранников?.

 - Женщина улыбнулась и протянула ему тонкую изящную руку. - Дэвид Беккер.  - Он пожал ее руку.

    Under certain conditions, photosynthetic organisms can also produce hydrogen gas which is one of the cleanest sources of energy. About the Author. REZA.

    Solar energy is the only renewable energy source that has sufficient capacity for the global energy need as well as that addresses the issues of energy crisis and global climate change.
