Electrocatalytic CO2 Reduction

2021
In recent years, the Goddard group has turned to electrocatalysts as ideal systems for catalyst design where one can combine anode and cathode electrodes, with electrolytes, and applied fields to provide the flexibility to control complex reactions. In addition to the oxygen reduction reaction (ORR) at the cathode of the hydrogen fuel cell discussed in

Relays for CO2 Reduction

ATZelektronik worldwide, 2010
The major challenge is to reduce the power consumption in the vehicle in such a manner that the customer does not notice. It is possible to take a step closer to this goal by using bistable relays with a low power consumption that do not consume any holding current, Tyco Electronics explains.

CO2 Reduction and Utilization

2015
As CO2 capture technology is employed extensively, the volume of CO2 that is released through various processes has potential to surpass the limited amount of storage capacity. One sustainable way to deal with CO2 is to convert it into a usable form, such as for energy.

Photocatalytic CO2 Reduction

2015
In the context of finding sustainable and environmentally neutral alternatives to fossil fuels, there is much current interest in the production of chemicals that can be used as fuels using solar light (solar fuels). In the present chapter, we describe the fundamentals and the current state of the art for the photocatalytic reduction of CO2, making ...

Photocatalytic Reduction of CO2

2017
As compared to other methods for CO2 reduction, the photocatalytic conversion of CO2 has a unique advantage of direct utilization of solar energy. In this sense, this pathway is similar to the biological photosynthesis. However, despites decades of quite intensive research, mechanisms of the catalytic photoreduction of CO2 are still not well ...

Modeling CO2 reduction on Pt(111)

Physical Chemistry Chemical Physics, 2013
Density functional theory was used to model the electrochemical reduction of CO2 on Pt(111) with an explicit solvation layer and the presence of extra hydrogen atoms to represent a negatively charged electrode. We focused on the electronic energy barriers for the first four lowest energy proton-electron transfer steps for reducing CO2 on Pt(111 ...

Electrocatalytic Reduction of CO2

2017
Renewable sources, such as solar and wind electricity, are attractive alternatives to fossil energy, because they are CO2 neutral and, therefore, do not contribute to the greenhouse effect. However, these types of renewable energy are not available on demand due to their transient character.

Mission CO2 Reduction

2016
In the race to achieve global CO2 targets, longer gear ratios helps to reduce fuel consumption in significant extent. The operating point of the internal combustion engine then shifts to lower speeds and specific torque is increased. Both measures lead to more pronounced rotational irregularity, however.

CO2 Reduction by Photoelectrochemistry

2016
CO2 reduction using sunlight energy is one of the ultimate methods for addressing issues related to global warming and a fossil fuel shortage, and constructing a carbon-neutral society in the future. Therefore, the amount of research in this field has been increasing in the 2010s.

Reductive activation of CO2 by formate dehydrogenases

2018
Two factors, climate change brought on by rising atmospheric CO2 levels and the accelerating shift toward renewable energy sources, have together worked to heighten interest in understanding how biological catalysts so effectively bring about the reduction of CO2 to formate, with potential applications for both bioremediation and energy storage.
