摘要：NOVELTY - Constructing silver phosphate-based composite catalyst unit bond comprises e.g. preparing silver phosphate ordered structure, establishing membrane transport system, in semipermeable membrane binding activity of small organic molecules complex template, through membrane transport controlling nucleation formation number and crystal growth rate, utilizing composite template containing -OH, -COOH, achieving crystal growth orientation control, semi-permeable membrane containing pore canal structure, can for crystal growth to space confinement effect to obtain different morphologies. USE - The method is useful for constructing silver phosphate-based composite catalyst unit bond (claimed). ADVANTAGE - The catalyst has excellent light catalyze activity and high degrading effect. The method greatly decreases use amount of phosphoric acid silver and cost. DETAILED DESCRIPTION - Constructing silver phosphate-based composite catalyst unit bond comprises (i) preparing silver phosphate ordered structure, establishing membrane transport system, in semipermeable membrane binding activity of small organic molecules complex template, through membrane transport controlling nucleation formation number and crystal growth rate, utilizing composite template containing -OH, -COOH and other active groups, achieving crystal growth orientation control, semi-permeable membrane containing pore canal structure, can for crystal growth to space confinement effect to obtain different morphologies with different pore size and distribution of phosphoric acid silver base material, (ii) silver phosphate crystal surface composite thickness is nanoscale anatase titanium dioxide, i.e. placing step (i) phosphoric acid silver base material in N-butyl titanate aqueous solution, adding ethyl alcohol, carrying out hydrolysis to obtain hydroxide, produced hydroxy again and silver phosphate-containing surface hydroxy groups, carboxy group through hydrogen and other bond cooperation binding, heating dehydration process, binding titanium dioxide to surface of silver phosphate crystals obtaining porous phosphoric acid silver base composite catalyst unit.
