摘要: Abstract Besides the common usage of TiO2-based photocatalyst in photodegradation organic pollutants and water photosplitting, these interesting semiconductors materials could be invoked this study to hydrolyze ammonium phosphate release hydrogen. In other words, phosphates utilized as hydrogen storage materials. Stoichiometrically, mono-, di- tri-ammonium can lead evolve 3.875, 7.867 11.903 equivalent, respectively. Briefly, Ag-, Cd- Zn-doped TiO2 nanofibers with different doping content (0, 0.5, 1.0 1.5 wt%) have been synthesized by electrospinning process. Generally, increasing dopant leads enhance photohydrolysis all formulations produce more Compared two formulations, Ag-doped (1.5 wt% Ag) showed best photocatalytic activity obtained was 41, 37 35 ml from 1 mmol phosphate, Analyzing gases GC confirms evolution pure Moreover, ion chromatography detects nitrate nitrite ions liquid which indicates hydrolysis phosphate. Overall, opens promising avenue develop new photocatalysts
