NEW ADVANCES IN CO2 PHOTOREDUCTION VI ARTIFICIAL PHOTOSYNTHESIS

MOLECULAR SURFACE COATINGS FOR APPLICATIONS IN ARTIFICIAL PHOTOSYNTHESIS

Applications of artificial intelligence - Wikipedia

The replacement of fossil fuels by a clean and renewable energy source is one of the most urgent and challenging issues our society is facing today, which is why intense research is devoted to this topic recently. Nature has been using sunlight as the primary energy input to oxidize water and generate carbohydrates (a solar fuel) for over a billion years. Inspired, but not constrained, by nature, artificial systems can be designed to capture light and oxidize water and reduce protons or other organic compounds to generate useful chemical fuels. Significant progress has been made recently in artificial photosynthesis based on molecular chemistry and material science. However, developments in these two areas have occurred more independently than what is perhaps desired. In the present meeting, we will bring together researchers in these two scientific communities to explore possible synergistic effects of “fusion” between molecular and materials systems.

This conference will appeal to researchers from both molecular and materials communities interested in the latest findings for artificial photosynthesis. We expect to see attandance from Professors, Postdocs and Graduate Students from across these disciplines.

AB - In order for solar energy to serve as a primary energy source, it must be paired with energy storage on a massive scale. At this scale, solar fuels and energy storage in chemical bonds is the only practical approach. Solar fuels are produced in massive amounts by photosynthesis with the reduction of CO2 by water to give carbohydrates but efficiencies are low. In photosystem II (PSII), the oxygen-producing site for photosynthesis, light absorption and sensitization trigger a cascade of coupled electron-proton transfer events with time scales ranging from picoseconds to microseconds. Oxidative equivalents are built up at the oxygen evolving complex (OEC) for water oxidation by the Kok cycle. A systematic approach to artificial photo synthesis is available based on a "modular approach" in which the separate functions of a final device are studied separately, maximized for rates and stability, and used as modules in constructing integrated devices based on molecular assemblies, nanoscale arrays, self-assembled monolayers, etc. Considerable simplification is available by adopting a "dye-sensitized photoelectrosynthesis cell" (DSPEC) approach inspired by dye-sensitized solar cells (DSSCs). Water oxidation catalysis is a key feature, and significant progress has been made in developing a single-site solution and surface catalysts based on polypyridyl complexes of Ru. In this series, ligand variations can be used to tune redox potentials and reactivity over a wide range. Water oxidation electrocatalysis has been extended to chromophore-catalyst assemblies for both water oxidation and DSPEC applications.

N2 - Artificial photosynthesis using LiNbO3 as a photocatalyst has emerged as an important technology leading to the formation of eco-friendly end products. An interesting part of this technology is its ability to directly convert pollutants into the harmless substances in the contaminant source. This technology possesses enormous potential for the reduction of "global warming." This article reviews recent developments and future potential applications of this emerging technology and provides information on the parameters that control its process. The effects of the photosynthetic reaction of LiNbO3 on cementations materials and indoor air conditioning are also reviewed in this article.
