阐述研究方法与结果

Good morning, everyone. Thanks for coming. Today, I'll be presenting our research on novel photocatalysts for environmental remediation. Let's dive right into our methodology.

For our synthesis, we employed a hydrothermal method followed by calcination, which, as you can see from this slide, yielded highly crystalline materials. We carefully optimized reaction parameters such as temperature and time to ensure maximum purity and yield.

That's interesting. Could you elaborate a bit more on the specific challenges you faced during the controlled synthesis of these highly crystalline materials?

Certainly. The primary challenge was preventing uncontrolled particle growth while maintaining high crystallinity. We mitigated this by introducing a precise amount of capping agent, which allowed us to fine-tune the crystal size distribution.

Moving on to the results, here we have the degradation efficiency of various organic pollutants under UV irradiation. As the graph clearly illustrates, our novel catalyst, marked in red, consistently outperformed the commercial standard.

Impressive performance. What analytical techniques did you employ to quantify the degradation products and ensure complete mineralization, not just transformation?

Great question. We utilized Gas Chromatography-Mass Spectrometry, or GC-MS, for identifying intermediate products, and Total Organic Carbon, or TOC, analysis to confirm the complete mineralization of pollutants into CO2 and water. The TOC results, in particular, were very encouraging.

Finally, for the data analysis, all experiments were conducted in triplicate, and the error bars represent the standard deviation, ensuring statistical robustness. We also performed kinetic modeling to determine the reaction order and rate constants.
