【摘要】 在这项工作中,由许多薄片组装三氧化钨分级结构已被成功地通过简便不含表面活性剂的水热法制备。形貌和合成后产物的微观结构是。已获得的三氧化钨分级结构通过调节反应时间和硫酸钠的用量,提出可能的生长机理。所制备的产品被作为一种光催化剂,降解有毒有机染料,如:亚甲基蓝,曙红和刚果红。此外,三氧化钨分层结构研究不同形貌对亚甲基蓝降解率进行研究,揭示了分级结构的三氧化钨具有较好的光催化性能。表明所制备的产品可能会在废水的净化,拥有广阔的应用前景。更多还原

【Abstract】 In this work,WO₃ hierarchical structures assembled by many nanosheets have been successfully fabricated through a facile and surfactant-free hydrothermal method.A possible growth mechanism of the as-obtained WO₃ hierarchical structures is proposed by adjusting reaction time and the dosage of Na₂SO₄.The as-prepared WO₃ products are further regarded as a kind of photocatalyst for the photocatalytic degradation of three toxic organic dyes,Methylene Blue（MB）,Eosin Red（ER） and Congo Red（CR）.In addition,degradation efficiencies of WO₃products with different morphologies towards MB are also investigated,revealing that hierarchical WO₃ structures possess preferable photocatalytic performance.It demonstrated that the as-prepared products may be promising application in wastewater purification.更多还原
