Introducing an external photo field would effectively enhance electrocatalysis such as electrocatalytic CO2 reduction reaction (CO2RR), but suffering from the limited utilization efficiency of the photo-generated carriers. To address this challenge, a research team led by Professor Yuan-Biao Huang at the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Science, has successfully encapsulated metal halide perovskite quantum dots (e.g. CsPbBr3) with high light-absorption coefficients, into a cobalt-porphyrin-based covalent–organic frameworks (COFs) host (COF-366-Co). The synthesized perovskite-COF composite material, effectively improve the performance of the photocoupled electrochemical CO2RR.
Physicists at the University of Oxford have successfully simulated how light interacts with empty space—a phenomenon once thought to belong purely to the realm of science fiction.
The simulations recreated a bizarre phenomenon predicted by quantum physics, where light appears to be generated from darkness.
The findings pave the way for real-world laser facilities to experimentally confirm bizarre quantum phenomena.
The results have been published today (5 June) in Communications Physics.
Seoul National University College of Engineering announced that the research team of Professors Jeyong Yoon and Jaeyune Ryu from the Department of Chemical and Biological Engineering, in collaboration with Professor Jang Yong Lee’s team from Konkuk University’s Department of Chemical Engineering, has developed a new water electrolysis operation strategy that can produce green hydrogen without complex catalyst manufacturing processes.
The research team presented the possibility of significantly increasing hydrogen production efficiency without the use of precious metal-based catalysts. As a result, this research outcome is expected to be a technological turning point that accelerates the realization of a carbon-neutral society.
These findings were published on May 23th in the world-renowned journal Nature Communications under the title “Dynamic polarization control of Ni electrodes for sustainable and scalable water electrolysis under alkaline conditions.”
