Engineers have developed a catalyst by adding a flat platinum interface to NiFe-layered double hydroxide (LDH). The new catalyst increases hydrogen production efficiency and displays 11.2 times higher activity than conventional catalysts.
Ang butter bread, made by layering butter and red bean spread, creates a new flavor by combining the softness of butter and sweetness of red beans. Hydrogen-generating catalysts can also create synergistic effects when different materials are layered with their unique properties. Recently, a Korean research team has developed a technology to enhance the hydrogen generation efficiency by flattening platinum (Pt) over the surface of NiFe-layered double hydroxide (LDH). Recently published as a supplementary cover of the Journal of the American Chemical Society, this study was conducted by a POSTECH research team led by Professor In Su Lee, Research Professor Soumen Dutta, and Dr. Yu-Rim Hong (of the Department of Chemistry) in collaboration with Professor Si-Young Choi (Department of Materials Science and Engineering) and Professor Jeong Woo Han (Department of Chemical Engineering). Platinum combines well with hydrogen and is often…
