In recent years, lanthanum hydroxide (La (OH) 3) material has been widely applied in areas such as heterogeneous catalysis, materials, hydrogen storage materials, electrode materials, and superconducting materials. Its performance largely depends on particle size, aggregation, pore volume and surfac.....

氧化是將石油化學基的原料轉化成更高氧化狀態的通用化學品的核心技術。然而，氧化反應對環境提出了一些極大的挑戰。許多工業氧化方法涉及重金屬或腐蝕性試劑，並且耗能高。例如，對苯二甲酸是前50種化學品之一,年產40萬公噸，也依賴於氧化反應。本發明的目的是, 在進行化學品生產過程中，通過避免使用有毒的試劑，減少或甚至避免使用揮發性有機溶劑, 同時提高能源效率, 盡量減少對環境的負面影響。綠色氧化草案已經成立，它可與現時行業所採用的技術媲美。一個很好的例子，證實進行對二甲苯的氧化生產苯二甲酸時, 可使用水作某介,而不涉及重金屬試劑。
