文摘

PdAg/SiO2-NH2 catalyst for catalytic nitrate reduction with HCOOH as reducing agent. The closed reaction system enhanced catalytic nitrate reduction activity. Surface -NH2 modification enhanced nitrate reduction efficiency. PdAg/SiO2-NH2 demonstrated better nitrate reduction efficiency than PdCu/SiO2-NH2. Different optimal Ag contents for catalytic HCOOH decomposition and nitrate reduction.
