Fe-Based Catalysts Discovered In Light-Driven CO
2 Hydrogenation To Value-Added Hydrocarbons
Chinese researchers recently prepared a series of Fe-containing catalysts from MgFeAl Layered Double Hydroxide (LDH) nanosheet by thermal reduction with H2 at temperatures ranging from 300 °C to 700 °C. The new discovery is applied to the light-driven reduction of CO2 to value-added hydrocarbons for the first time.
This research, published online in Adv. Energy. Mater., was directed by Prof. ZHANG Tierui from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences (CAS).
Catalytic reduction of CO2 to value-added hydrocarbons is one of the most important chemical industrial processes in human society. In the pursuit of low-energy consumption of CO2 hydrogenation, solar-driven photothermal catalysis for the production of solar fuels has been attractive and popular in the past few years.

Abstract:
Lithium is an energy-critical element that is considered to be a geopolitically significant resource. However, the supply of lithium may not be enough to meet continuously increasing demand. As a result, scientists are looking for new ways to extract lithium ions.
Bionic idea boosts lithium-ion extraction

Ion selective membranes have already been used extensively for water treatment and ion sieving in electrodialysis technology. However, conventional membranes exhibit low and useless Li+ selectivity, making them insufficient for meeting industry requirements.
Chinese scientists have recently made progress in the preparation and application of a bioinspired material that is capable of achieving controlled ion transport and sieving, especially for lithium-ion extraction.
