An intimate CuPd(100) interface was designed to lower the energy barriers of intermediate reaction (CO2 hydrogenation and C-C coupling) and improve the efficiency of C2 products. The optimal CuPd(100) interface catalyst exhibited a C2 Faradaic efficiency of 50.3%, which was 2.1 times higher than that of Cu catalyst (23.6%) at -1.4 VRHE in 0.1 M KHCO3

Recently a research group from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) performed numerical simulation and experimental demonstration of a pixelated metasurface based on the silicon-on-insulated (SOI) wafer.
Three-dimensional schematic of the pixel unit. The colors are used only for the distinguishment of the image and bear no wavelength information. (F0, F1, F2) and F3 represent linear polarizers and circular polarizer, respectively. Image Credit: Shanghai Institute of Optics and Fine Mechanics.
