Abstract

Photodecomposition of polyvinylpyrrolidone in solutions of metal nitrates is studied. This polymer oxidates in metal nitrate solutions under UV irradiation by reacting with reactive oxygen species and thus inhibits photodecomposition of other organic materials. UV irradiation of polyvinylpyrrolidone-stabilized ZnO nanoparticles leads to removal of polyvinylpyrrolidone and growth of nanoparticles.

聚乙烯吡咯烷酮在金属硝酸盐水溶液中的光解

摘要

研究了聚乙烯吡咯烷酮在金属硝酸盐溶液中的光分解。该聚合物在紫外线辐射下与活性氧发生反应，在金属硝酸盐溶液中氧化，从而抑制了其他有机材料的光分解。聚乙烯吡咯烷酮稳定的ZnO纳米粒子的紫外线照射导致聚乙烯吡咯烷酮的去除和纳米粒子的生长。
