Abstract. The surfaces of metal and metal oxide nanomaterials are covered with a large amount of charge, which was responsible for their superb electron properties []. When elements react with oxygen, they form oxides. [1] C Horizon. 000 spezielle materialien für forschung und entwicklung auf lager. The magic reducible oxides properties likely are mainly due to the presence of oxygen defects and their rich surface chemistry, which provide a rational pathway to the emergent of entirely new properties.
