A green approach for the synthesis of novel Ag ₃ PO ₄ /SnO ₂ /porcine bone and its exploitation as a catalyst in the photodegradation of lignosulfonate into alkyl acids

for the decrease in the probability of electron-hole recombination and improved performance in the presence of hierarchical porous porcine bone (hydroxyapatite). This paper also analyzed the change of the molecular weight and structure of sodium lignin sulfonate in the photocatalytic reaction and discussed the possible photocatalytic mechanism of the photocatalyst composite, indicating that the benzene rings of guaiacol were oxidized into different alkyl acids (maleic acid, oxalic acid, formic acid and methoxy acetic acid).
