Discontinuous cobalt manganese oxyhydroxide (CMOH) film shows much higher atom efficiency and performance in the oxygen evolution reaction (OER) than the completely continuous ones. In article number 1903363, Jiaxing Huang, and Chun‐Hu Chen, and co‐workers prove that the heterojunction edges are responsible for the OER enhancement with facilitated charge transport and kinetics. This concept is highly...
Thin film electrocatalysts allow strong binding and intimate electrical contact with electrodes, rapid mass transfer during reaction, and are generally more durable than powder electrocatalysts, which is particularly beneficial for gas evolution reactions. In this work, using cobalt manganese oxyhydroxide, an oxygen evolution reaction (OER) electrocatalyst that can be grown directly on various electrodes...
The transparent TiO2 thin films coated on fused-SiO2 substrates were prepared by the sol–gel method and spin-coating technique. Effects of calcination temperature on crystal structure, grain size, surface texture, and light transmittance of the films were investigated. After calcining at 600–1,200 °C, the thicknesses of the TiO2 films were all around 80 nm and the molecular structures of the films...
TiO2 films deposited on GaN layers at room temperature through a simple and low-cost liquid-phase deposition (LPD) method are investigated. The deposition rate is 70 nm/hr. X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) are used to analyze chemical composition. Upon annealing under an atmosphere of high purity N2, the crystalline phase of TiO2 is transformed from the...
