X-ray diffraction analysis confirmed that crystalline nanoparticles (NPs) are face centered cubic structure.
However Bragg reflections with 2θ values of 37.72°, 44.18° and 64.42° correspond to the (111), (200) and (220) sets of lattice planes observed which may be indexed as the band for face centered cubic structures of both monometallic and bimetallic of silver and gold.

Therefore, in the high temperature, pressure and thermal load conditions, supercritical unit has higher demands on steam-water quality in operation, and appropriate water chemistry condition must be adopted to control the corrosion of feed-water system, especially flow accelerated corrosion (FAC), during both stable and variable operation, to ensure safe and economic operation for power plant.
Dissolved oxygen in steam affects the structure characteristics of oxide scale and its hierarchical structure.
