Effect of the synthesis variables of TiO2 on the photocatalytic activity towards the degradation of water pollutants

In this work, TiO2 photocatalysts were synthesized using a conventional sol-gel and hydrothermal synthesis methods with steam pressure treatment.Photocatalysts were characterized by X-ray diffraction (XRD), diffuse reflectance spectra Diapers (DRS) and N2 adsorption-desorption.The photoactivity of the samples was analyzed towards the photooxidation

Biogeographic distribution of autotrophic bacteria was more affected by precipitation than by soil properties in an arid area

IntroductionAutotrophic bacteria play an important role in carbon dioxide fixation and are widespread in terrestrial ecosystems.However, the biogeographic patterns of autotrophic bacteria and the driving factors still remain poorly understood.MethodsHerein, we conducted a 391-km north to south transect (mean annual precipitation <600 mm) survey
