Advanced photocatalysts that can utilize solar energy for water purification applications are always needed. The present article reports a facile fabrication of tungsten oxide (WO3)/bismuth oxychloride (BiOCl) immobilized on polyaniline (PAn) (BiOCl/WO3@PAn) heterojunction nanocomposite photocatalyst. designed nanocatalyst was tested 2-chlorophenol (2-CP) decontamination from the aquatic system. Synthesized WO3, BiOCl, and BiOCl/WO3@PAn nanocomposites were distinguished via UV-DSR, photoluminescence, SEM, TEM, XRD, XPS analysis. combination PAn with WO3 BiOCl showed synergistic impact photocatalytic efficiency nanocomposite. synthesized higher visible light absorption behavior bandgap reduction than BiOCl. obtained data shows 2-CP photocatalysis by is controlled degradation time, pH, pollutant amount in solution. highest (99.7%) recorded at pH 5 25 mg/L concentration within 240 min. mechanism active radical scavenging study discovered •O2− •OH, responsible mineralization onto enhanced properties over pristine catalysts. reusability evaluated.

Microbially Induced Carbonate Precipitation (MICP) technology offers an innovative approach for the solidification and stabilization of heavy metal-contaminated soils; However, mechanical strength long-term stability this remediation method have not been thoroughly investigated. This study introduces curing technique using MICP-activated MgO to address geotechnical challenges posed by zinc ion-contaminated soils. To investigate effect ions on soil optimal efficacy in contamination, experiments were conducted zinc-contaminated soils with varying ion concentrations (0.05%, 0.1%, 0.5%, 1.0%), dry densities (1.35, 1.4, 1.45, 1.5 g/cm³), activated admixtures (1%, 2%, 5%, 10%). The effectiveness was evaluated through macroscopic analysis tests, including unconfined compressive direct shear Toxicity Characteristic Leaching Procedure (TCLP). results indicated that disrupted particle cementation, enlarged inter-particle pores, significantly reduced both strength. dosage determined be 10%, resulting 1.196 MPa a Zn2+ leaching concentration 0.1414 mg/L. combined actions facilitated formation alkaline magnesium carbonate, calcium hydroxide. These compounds filled pores soil, encapsulating co-precipitating ions, thereby enhancing soil's stability. findings establish theoretical foundation engineering application
