1：Experimental Design and Method Selection:

The study employed a solvothermal synthesis method for Zn2Te3O8 nanocrystals using zinc acetate and tellurium powder in beta-aminoethylamine solvent at 200°C for 6 hours. This method was chosen for its ability to produce highly crystalline materials with controlled defects.

2：Sample Selection and Data Sources:

The samples were synthesized in-house, and characterization data were obtained from various spectroscopic and microscopic techniques.

3：List of Experimental Equipment and Materials:

Equipment included autoclave for synthesis, Rigaku miniplex X-Ray diffractometer for XRD, Zeiss Gemini SEM 300 for SEM, Jasco Spectrophotometer for absorption spectra, Kratos Axis Ultra for XPS, JASCO instrument for Raman spectroscopy, JEOL model JES FA 200 for EPR, Luzchem photocatalytic reactor for degradation studies, and Inlabco orbital shaker for bacterial culture. Materials included zinc acetate, tellurium powder, beta-aminoethylamine, methanol, methylene blue dye, terephthalic acid, nutrient broth, nutrient agar, and Escherichia coli bacteria.

4：Experimental Procedures and Operational Workflow:

Synthesis involved mixing precursors in an autoclave and heating. Characterization included XRD, SEM, EDAX, absorption spectroscopy, XPS, Raman, EPR, and photocatalytic degradation tests using methylene blue dye under Xe lamp irradiation. Antibacterial tests used agar well diffusion method with E. coli.

5：Data Analysis Methods:

Data were analyzed using software like Material Studio 7.0 for crystal structure simulation, linear regression for kinetic studies, and fluorescence spectroscopy for ROS quantification.
