Please rewrite the following paragraphs to make them more logical and highlight the keyword:Subsequently, we also investigated the photocatalytic degradation of the precursor material of the best material PCN-134/PCN-134-1.33 to NZT, and found that the catalytic efficiency of Zr-BTB/PCN-134-1.33 (59.52%) was the best. From the above results, PCN-134/PCN-134-1.33 had the best catalytic performance, so it was named PCN-134/PCN-134 and used for subsequent research.

Following our initial investigation, we conducted a photocatalytic degradation study on the precursor material of the top-performing material, PCN-134/PCN-134-1.33, to NZT. The results showed that PCN-134/PCN-134-1.33 with Zr-BTB as the catalyst displayed the highest efficiency at 59.52%. Based on these findings, it was concluded that PCN-134/PCN-134-1.33 exhibited the best photocatalytic performance and was thus named PCN-134/PCN-134 for future research.

Ten mg of PCN-134/PCN-134 was weighed and dispersed in 100 mL of 40 mg/L NZT solution, stirred at 400 rpm on a magnetic stirrer and placed under a 500 W xenon lamp (Beijing Pulinsaisi, China) before the reaction started. At regular intervals, 3 mL of the mixed solution was removed and filtered through a 0.22μm nylon filter tip and subsequently measured by UV-Vis spectrophotometer at 314 nm. The photocatalytic performance of PCN-134/PCN-134 for NZT in the presence of different pH, anions and dissolved organic matter (DOM) was then investigated. The photocatalytic performance of PCN-134/PCN-134 was investigated after 5 times of repeated use.

In the quartz reactor, photocatalytic degradation tests were conducted using PCN-134/PCN-134. The process involved weighing 10 mg of PCN-134/PCN-134 and mixing it with 100 mL of a 40 mg/L NZT solution, which was stirred at 400 rpm using a magnetic stirrer. The reaction was initiated by exposing the mixture to a 500 W xenon lamp (Beijing Pulinsaisi, China). Samples were collected at regular intervals by removing 3 mL of the mixture, which was then filtered through a 0.22μm nylon filter tip and analyzed using a UV-Vis spectrophotometer at 314 nm to evaluate the photocatalytic performance of PCN-134/PCN-134 for NZT in various conditions such as different pH levels, the presence of anions and dissolved organic matter (DOM). Additionally, the photocatalytic performance of PCN-134/PCN-134 was re-evaluated after 5 repeated uses.
