Headline: Combating carbon footprint: Novel reactor system converts carbon dioxide into usable fuel

■ Release Date: 2024.5.27

■ Published by: Shibaura Institute of Technology

■ Keywords: boilers, greenhouse gas, methane

■ Abstract:

Boilers are a major source of greenhouse gas emissions. In a recent study, researchers developed a method to convert CO2 emissions from small boilers into methane, which makes use of an optimized reactor design that evenly distributes the CO2 feed. This, in turn, results in significantly lower temperature increments and a boost in methane production. This innovative technique could pave the way for reducing greenhouse gas emissions.

Headline: A novel multifunctional catalyst turns methane into valuable hydrocarbons

■ Release Date: 2024.5.29

■ Published by: catalyst, methane, hydrocarbons

■ Keywords: Tokyo Institute of Technology

■ Abstract:

The optimal design of a novel zeolite catalyst enables tandem reaction that turns greenhouse gases into value-added chemicals, report scientists. By tuning the separation between different active sites on the catalyst, they achieved the stepwise conversion of methane into methanol and then to hydrocarbons at mild conditions. These findings will help reduce energy costs and greenhouse gas emissions across various industrial fields.

Headline: Graphene gets cleaned up

■ Release Date: 2024.5.29

■ Published by: Columbia University School of Engineering and Applied Science

■ Keywords: graphene, carbon, oxygen

■ Abstract:

Engineers establish the link between oxygen and graphene quality and present an oxygen-free chemical vapor deposition method (OF-CVD) that can reproducibly create high-quality samples for large-scale production. The graphene they synthesized with their new method proved nearly identical to exfoliated samples and was capable of producing the fractional quantum Hall effect.

Headline: Solving the problems of proton-conducting perovskites for next-generation fuel cells

■ Release Date: 2024.5.29

■ Published by: Tokyo Institute of Technology

■ Keywords: perovskite, fuel cells, proton

■ Abstract:

As a newly developed perovskite with a large amount of intrinsic oxygen vacancies, BaSc0.8W0.2O2.8 achieves high proton conduction at low and intermediate temperatures, report scientists. By the donor doping of large W6+, this material can take up more water to increase its proton concentration, as well as reduce the proton trapping through electrostatic repulsion between the dopant and proton. These findings could pave the way to the rational design of novel perovskites for protonic ceramic fuel cells (PCFCs) and electrolysis cells (PCECs).

Headline: New method makes hydrogen from solar power and agricultural waste

■ Release Date: 2024.5.30

■ Published by: University of Illinois Chicago

■ Keywords: hydrogen gas, solar power, energy

■ Abstract:

Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
