Abstract
The catalytic conversion of CO2 is a
key component for the reintegration of secondary products like CO2 or
H2 into the energy supply. The “power to gas” concept is one
example, involving the conversion of CO2 into CH4. The CO2
is transferred into a carrier of chemical energy, making it possible to feed
the produced CH4 into the existing natural gas network.
Authors
report on the experimental setup in laboratory scale, which enables an advanced
characterization of the catalytic performance, including thermodesorption
measurements at atmospheric pressure in order to determine the amount of
adsorbed CO2 under real conditions. They also present data for
activation energies, the catalytic performance as function of temperature and
the long time stability of a commercial Ru-based catalyst.

Abstract
CO2 is the key molecule in the effort to replace part of fossil fuel consumption by renewable energy. Authors describe the routes, opportunities and barriers to increasing the share of renewable energy by using CO2 reaction and their impact on the chemical and energy value chains. They focus on the catalytic aspects of the chemistries involved, an analyze the state-of-the-art, perspectives and targets to be developed.
They discuss the production of short-chain olefins from CO2, and the conversion of carbon dioxide to syngas, formic acid, methanol and dimethyl ether, hydrocarbons via Fischer–Tropsch synthesis and methane. They conclude by presenting a possible scenario for CO2 as an intermediary for the incorporation of renewable energy in the process industry, with a roadmap for catalysis needs and barriers to reaching this goal.

Abstract
Presents an innovative hybrid technology that employs renewable hydrogen (H2) and carbon dioxide (CO2) sequestered from large point sources to produce fuels and chemicals. Researchers studied the feasibility of using two acetogenic bacteria to metabolize H2 and CO2 for the production of ethanol.
They performed three experiments in small scale reactors to select a bacterium, feed gas composition and nutrient medium source to produce ethanol. Results suggested that Clostridium carboxidivorans produced 33% more ethanol and 66% less acetic acid compared to Clostridium ragsdalei. This makes C. carboxidivorans the better candidate for ethanol production. The study highlights the significant role that acetogenic microbes can play in CO2 conversion into valuable fuels and chemicals.

Abstract
Describes preparation of well-dispersed g-C3N4 nanophases in SBA-15 mesochannels using a two-step vapor condensation of dicyandiamide. Defect-containing g-C3N4 nanophases were active catalysts for CO2 activation. Activated CO2 species were steadily converted to target compounds with a high selectivity. Doped metal ions promoted the catalytic activity and selectivity significantly.
Zn2+-doped g-C3N4/SBA-15 exhibited a high activity in transferring CO2 to epoxides. Fe3+-doped g-C3N4/SBA-15 was an efficient catalyst for the direct oxidative cycloadditon of CO2 to olefins. Styrene was converted into 4-phenyl-1, 3-dioxolan-2-one. The process conversion was 34.1% and the selectivity to the oxidative cycloaddition product reached 93%.
