Abstract The development of efficient electrocatalysts based on non-noble metals for oxygen evolution reaction (OER) remains an important and challenging task. Multinuclear transition-metal clusters with high structural stability are promising OER catalysts but their catalytic role is poorly understood. Here we report the crystallographic observation activity over robust {Ni 12 }-clusters immobilised in a porous metal-organic framework, NKU-100, by single-crystal X-ray diffraction as...
Three-dimensional hierarchical tin oxide microspheres (HM-SnO2) are successfully synthesized by hydrothermal treatment. The SnO2 with diameter of 1–4 μm pure rutile phase and consist nanosheets. two-dimensional nanosheets ensure fast electron transport slow charge carrier recombination. Due to their large particle size, the HM-SnO2 films can scatter light efficiently enhance harvesting. Because above advantages, a dye-sensitized solar cell (DSSC) based on photoanode shows an energy...
The reduction of hematite with ammonia is a potentially environmentally friendly method ironmaking. Previous studies on pellets typically involved samples weighing only 2.8 g and lacked detailed activation energy analysis for the ammonia-hydrogen co-reduction pellets. Therefore, to further investigate thermodynamics kinetics NH3–H2 pellets, this study uses 50 experiments. By increasing pellet mass, expands scope kinetic research results indicate that nitrogen gas produced from decomposition...
