摘要: 通过引入氨辅助浸渍和载体预处理等关键变量，对综合化学实验“负载型镍基催化剂上的甲烷选择氧化反应”进行了系统优化。通过催化剂制备、性能评价、程序升温还原表征以及物理/化学吸附测试等完整实验流程，让学生在实验过程中深刻体验酸洗载体消减杂质和氨辅助浸渍提高金属分散度对Ni/SiO₂催化性能的显著提升作用，全面认识影响催化性能的多重因素，激发深入研究催化化学复杂作用机制的兴趣。改进后的实验有效克服了传统实验内容单一、缺乏对比维度等不足，在教学实践中取得了良好的效果。

Abstract: The comprehensive chemistry experiment titled “Selective Oxidation of Methane over Supported Nickel-Based Catalysts” has been systematically optimized through the introduction of key variables, including ammonia-assisted impregnation and support pretreatment. Through a complete experimental workflow encompassing catalyst preparation, performance evaluation, temperature-programmed reduction characterization, and physical/chemical adsorption measurements, students gain practical insights into how support purification via acid-washing and ammonia-assisted impregnation for enhanced metal dispersion significantly improves the catalytic performance of Ni/SiO₂. This approach enables students to comprehensively understand the multifaceted factors influencing catalytic performance and stimulates their interest in exploring the complex mechanisms of catalytic chemistry. The enhanced experiment effectively addresses the limitations of traditional experiments, such as content monotony and insufficient comparative dimensions, demonstrating excellent efficacy in teaching practice.
