摘要：基于提升本科生创新实践能力的培养目标,设计综合实验"钼酸银/溴化银/银纳米复合材料的制备及催化性能研究"。实验通过水热法合成钼酸银球状晶,根据溶度积常数的差异实现钼酸银-溴化银的原位复合,再引入感光技术在二元复合材料表面进一步沉积纳米银颗粒,利用单质银的等离子体共振效应显著提高材料的光催化性质。该综合实验将复合材料制备、性能研究和实际应用有机结合,通过模拟科研全流程,改革教学方式方法,激发学生的学习兴趣和研究热情,拓展学生的科学视野,培养学生的创新思维和科研素养,增强学生解决实际问题的能力,从而有效提高教学质量。
Based on the training purposes of promoting the innovation ability of undergraduates, the research results of "preparation, characterization and photocatalytic performance of Ag@Ag2MoO4-AgBr nanocomposite" were adapted to a comprehensive experiment. According to the difference of solubility product of AgBr and Ag2MoO4 crystals, the Br- replaced the MoO 2- 4 in a crystal lattice node of Ag2MoO4 which was prepared via hydrothermal route to in-situ form the Ag2MoO4-AgBr composites which could exhibit new characteristics. Then the silver nanoparticles were coated on the surface of Ag2MoO4-AgBr composite through photo-deposition. The silver nanocrystals on the surface of Ag2MoO4-AgBr could generate the surface plasmon resonance (SPR) under visible light irradiation and produce photo-excited species, which could degrade dyes efficiently. This comprehensive experiment covers the synthesis, characterization and performance of the functional materials, as well as their practical applications, which could simulate the whole process of scientific research. This beneficial trial can improve the professionalism, innovation, interests and enthusiasm for research of undergraduates as well as enhance their scientific literacy and the ability to solve practical problems, which helps to enhance the quality of teaching in the end.
