Presenter (Male)

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.

大家早上好，感谢各位的到来。今天，我将介绍我们关于新型光催化剂在环境修复方面的研究。让我们直接进入研究方法部分。

Presenter (Male)

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.

在合成方面，我们采用了水热法，随后进行了煅烧，正如大家从这张幻灯片上所看到的，这产生了高结晶度的材料。我们仔细优化了反应参数，如温度和时间，以确保最高的纯度和产率。

Observer 1 (Female)

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

这很有趣。您能再详细说明一下在这些高结晶度材料的受控合成过程中遇到的具体挑战吗？

Presenter (Male)

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.

当然。主要的挑战是如何在保持高结晶度的同时防止颗粒的无序生长。我们通过引入精确量的封端剂来解决这个问题，这使我们能够微调晶体尺寸分布。

Presenter (Male)

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.

接下来看实验结果，这里展示了在紫外线照射下各种有机污染物的降解效率。正如图表清晰所示，我们用红色标记的新型催化剂，持续优于商业标准。

Observer 2 (Male)

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

性能令人印象深刻。您采用了哪些分析技术来量化降解产物并确保完全矿化，而不仅仅是转化？

Presenter (Male)

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.

问得好。我们利用气相色谱-质谱联用仪（GC-MS）来识别中间产物，并使用总有机碳（TOC）分析来确认污染物完全矿化为二氧化碳和水。特别是TOC结果非常令人鼓舞。

Presenter (Male)

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.

最后，关于数据分析，所有实验均进行了三次重复，误差条表示标准差，确保了统计的稳健性。我们还进行了动力学建模，以确定反应级数和速率常数。
