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.

Please rewrite the following paragraphs to make them more logical and highlight the keyword: Photocatalytic degradation tests were performed in a quartz reactor. 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.

You will need to rewrite or cast the expression.

In PostgreSQL, if you encounter the error "You will need to rewrite or cast the expression", it means that the database is unable to implicitly convert or cast the expression to the desired data type.

To resolve this issue, you have a few options:

1. Use explicit casting: If you know the desired data type for the expression, you can use explicit casting to convert it. For example:

   SELECT column_name::desired_data_type FROM table_name;

Replace `column_name` with the actual column name and `desired_data_type` with the appropriate data type, such as `integer`, `text`, etc.

2. Modify the expression: If the expression is not compatible with the desired data type, you might need to modify it. This could involve changing operators, functions, or performing additional calculations to achieve the desired result.

3. Use a different function or operator: If the current function or operator is causing the error, you can try using a different function or operator that is compatible with the desired data type.

It's important to review the specific error message and the context in which it occurs to determine the best course of action. Refer to the PostgreSQL documentation for more information on data type casting and available functions/operators.
