摘要: The article considers the influence of acid–base and structural-adsorption properties on photocatalytic activity TiO2 TiO2–SnO2 nanocomposites obtained by hydrolytic (HL) hydrothermal (HT) synthesis methods. Acid–base were evaluated Hammett indicator method. Structural-adsorption studied using Brunauer–Emmett–Teller surface analysis (BET). Photocatalytic was determined photodegradation methylene blue (MB) Congo red (CR) organic dyes. Synthesized materials also characterized X-ray fluorescence (XRF), powder diffraction (PXRD), high-resolution transmission electron microscopy (HRTEM), scanning (SEM), Raman spectroscopy photoelectron (XPS). All synthesized photocatalysts are mesoporous with developed area. results demonstrated that HT series samples both acidic basic sites Bronsted type universal sorbents effectively remove cationic anionic HL composites only selective towards improved performance sample containing 1% SnO2 may attribute to increased area high content different types.
