New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

Oceans Lock Away Carbon Slower Than Previously Thought

Cars That Think

Research expeditions conducted at sea using a rotating gravity machine and microscope found that the Earth’s oceans may not be absorbing as much carbon as researchers have long thought. Oceans are believed to absorb roughly 26 percent of global carbon dioxide (CO 2 ) emissions by drawing down CO 2 from the atmosphere and locking it away.

ExxonMobil, UC Berkeley, Berkeley Lab develop new MOF for carbon capture and steam regeneration

Green Car Congress

Scientists from ExxonMobil, University of California, Berkeley and Lawrence Berkeley National Laboratory have developed a new material that could capture more than 90% of CO 2 emitted from industrial sources using low-temperature steam, requiring less energy for the overall carbon capture process.

Multicomponent catalytic system efficiently converts carbon dioxide to methanol

Green Car Congress

Inspired by naturally occurring processes, a team of Boston College chemists used a multi-catalyst system to convert carbon dioxide to methanol at the lowest temperatures reported with high activity and selectivity. It can be produced from hydrogen and carbon dioxide, mitigating greenhouse gas emissions and storing hydrogen in the process.

Leclanché reduces cobalt in NMCA cells from 20 to 5%; 20% higher energy density; water-based production

Green Car Congress

Leclanché SA has reduced the cobalt content in NMCA as cathode material from 20% to 5% and manufacture the electrodes using an environmentally friendly water-based process. In doing so, Leclanché completely dispenses the use of the highly toxic organic solvents (NMP) that are otherwise common in the production process.

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

Researchers from Huazhong University of Science and Technology in China and George Washington University in the US report in a new paper in the ACS journal Accounts of Chemical Research that a range of important carbon nanomaterials can be produced at high yield by molten carbonate electrolysis.

Researchers develop organic semiconductor photocatalyst with enhanced hydrogen evolution

Green Car Congress

However, photocatalysts formed from a single organic semiconductor typically suffer from inefficient intrinsic charge generation, which leads to low photocatalytic activities. They incorporated these materials into organic nanoparticles that can be tuned to absorb more of the visible light spectrum. Bidwell, M, Hyojung, C., Anjum, D.H.,
