Here we show the oxidation of black phosphorus (BP) can be fully utilized for osmotic energy conversion, which stands in contrast to using BP for electronic applications where the ambient stability is a major concern. In hypophosphoric acid the phosphorus atoms are identical and joined directly with a P−P bond. Many compounds with luster and electrical conductivity maintain a simple stoichiometric formula; such as the golden TiO, blue-black RuO 2 or coppery ReO 3, all of obvious oxidation state.Ultimately, however, the assignment of the free metallic electrons to one of the bonded atoms has its limits and leads to unusual oxidation states. In the case of phosphorus, the intermediate oxidation states disproportionate into +5 and -3 in both acids and alkalis. Let’s use this number in the following equation to determine the oxidation number of phosphorus. Guangxi Key Laboratory of Information … P = +5.
