Tribocatalysis is a method that converts mechanical energy into chemical energy. In this study, we synthesized tungsten bronze structured BaSrNbTaO ferroelectric ceramic submicron powder using a traditional solid-state route, and the powder exhibited excellent performance in tribocatalytic water splitting for hydrogen production. Under the friction stirring of three polytetrafluoroethylene (PTFE) magnetic stirring bars in pure water, the rate of hydrogen generation by the BaSrNbTaO ferroelectric submicron powder is 200 μmol h g, and after 72 hours, the accumulated hydrogen production reaches 15 892.8 μmol g. Additionally, this ferroelectric tungsten bronze ferroelectric material also exhibits excellent tribocatalytic degradation ability toward RhB dyes, with degradation efficiency reaching 96% in 2 hours. The study of tribocatalysis based on tungsten bronze ferroelectric materials represents a significant step forward in versatile energy utilization for clean energy and environmental wastewater degradation.
摩擦催化是一种将机械能转化为化学能的方法。在本研究中，我们采用传统的固态路线合成了钨青铜结构的BaSrNbTaO铁电陶瓷亚微米粉末，该粉末在摩擦催化水分解制氢方面表现出优异的性能。在纯水中由三根聚四氟乙烯（PTFE）磁搅拌棒进行摩擦搅拌的情况下，BaSrNbTaO铁电亚微米粉末的产氢速率为200 μmol h g，72小时后，累积产氢量达到15892.8 μmol g。此外，这种铁电钨青铜铁电材料对RhB染料也表现出优异的摩擦催化降解能力，2小时内降解效率达到96%。基于钨青铜铁电材料的摩擦催化研究在清洁能源的多功能能源利用和环境废水降解方面迈出了重要的一步。
